"Is the Relationship Between Numbers of References and Paper Lengths the Same
for All Science". Journal of the American Society for Information
Science and Technology, Vol. 53, No. 13, 2002, pp. 1106-1113.

Resumen: It has been shown in the physical sciences that a paper's
length is related to its number of references in a linear manner. Abt and
Garfield here look at the life and social sciences with the thought that if the
relation holds the citation counts will provide a measure of relative importance
across these disciplines. In the life sciences 200 research papers from
1999-2000 were scanned in each of 10 journals to produce counts of 1000 word
normalized pages. In the social sciences an average of 70 research papers in
nine journals were scanned for the two-year period. Papers of average length in
the various sciences have the same average number of references within plus or
minus 17%. A look at the 30 to 60 papers over the two years in 18 review
journals indicates twice the references of research papers of the same
length.

Special Reference to Pearson's Correlation Coefficient". Journal of
the American Society for Information Science and Technology, Vol. 54, No. 6,
2002, pp. 549-568 .
Descriptores: Análisis de citas/Bibliometría
Resumen: Ahlgren, Jarneving, and. Rousseau review accepted
procedures for author co-citation analysis first pointing out that since in the
raw data matrix the row and column values are identical i,e, the co-citation
count of two authors, there is no clear choice for diagonal values. They suggest
the number of times an author has been co-cited with himself excluding self
citation rather than the common treatment as zeros or as missing values. When
the matrix is converted to a similarity matrix the normal procedure is to create
a matrix of Pearson's r coefficients between data vectors.

Resumen: In this study scientists were asked about their own publication
history and their citation counts. The study shows that the citation counts of
the publications correspond reasonably well with the authors' own assessments of
scientific contribution. Generally, citations proved to have the highest
accuracy in identifying either major or minor contributions. Nevertheless,
according to these judgments, citations are not a reliable indicator of
scientific contribution at the level of the individual article. In the
construction of relative citation indicators, the average citation rate of the
subfield appears to be slightly more appropriate as a reference standard than
the journal citation rate. The study confirms that review articles are cited
more frequently than other publication types. Compared to the significance
authors attach to these articles they appear to be considerably 'overcited.'
However, there were only marginal differences in the citation rates between
empirical, methods, and theoretical contributions.

Resumen: O artigo tem por objetivo levantar e discutir as relações entre
a arqueologia do saber de Michel Foucault e a bibliometria. Propõe categorias de
análise comuns entre ambas as áreas. Reflete sobre temas de interesse comum
entre as duas disciplinas, tais como intertextualidade, citações, pragmática,
categorização dos discursos. Apresenta possibilidades de superação de limites
teórico-epistemológicos da bibliometria, tais como o problema da dificuldade de
se aferir a 'cientificidade' dos discursos selecionados para os estudos
bibliométricos, assim como a incorporação de categorias que permitam superar as
tendências de reificação identificadas nas pesquisas da ciência da informação.

Resumen: Se exponen los 50 artículos cubanos más citados en ciencias
biomédicas en el Web of Science. Se explican las ventajas y problemas de los
análisis de citas. Se utilizó como estrategia de búsqueda la palabra 'Cuba' en
el campo 'Author Address'. Se obtuvieron 7 141 artículos escritos por autores
cubanos o con su colaboración , entre 1988 y 2003; de ellos, se citó al menos
una vez el 50,8%. El promedio de citas por cada artículo fue de 2.68. El 78% de
los artículos fue generado con ayuda internacional. Se analizan brevemente los
campos temáticos tratados por los 50 artículos más citados, así como las
instituciones mejor representadas. Se concluye que los artículos compilados
pueden considerarse como los que mayor influencia han ejercido sobre la
comunidad científica internacional, si se considera su reconocimiento en la
literatura médica indizada en la más importante base de datos bibliográfica en

seleccionaron 34 revistas especializadas en la materia e indizadas por el
Institute for Scientific Information de Philadelphia, y se consultaron los
Journal Citation Report correspondientes al período evaluado para determinar el
factor de impacto promedio, así como el índice de incremento del factor de
impacto de cada una de ellas. Se calculó además el factor de impacto promedio
general de las revistas de 1992 a 1999, y se determinó el índice de incremento
general del factor de impacto promedio. Los resultados fueron graficados, y se
registraron las 10 mejores revistas de acuerdo con el factor de impacto promedio
más elevado, el mayor índice de incremento de su factor de impacto y los mayores
factores de impacto conseguidos en el período evaluado. Finalmente, se
comentaron las aplicaciones principales de la informática en la Biomedicina y se
destacó la utilidad de los análisis de citas realizados por el Institute for
Scientific Information para evaluar el comportamiento de una disciplina
biomédica.

Resumen: Tradicionalmente las revistas científicas utilizadas por los
investigadores universitarios se han encontrado ubicadas físicamente en la sede
de los distintos Departamentos, lo que ha producido la dispersión de títulos y
la variación de condiciones en cuanto a su accesibilidad. El objeto del presente
trabajo es racionalizar la accesibilidad a la información disponible. Con este
fin hemos analizado los usos de revistas por los distintos departamentos
basándonos en las citas recibidas en los trabajos realizados (ponderadas por el
número de autores de cada trabajo).Para este análisis hemos utilizado el
algoritmo de Kohonen, un modelo de red neuronal artificial, capaz de clasificar
las entradas (las revistas). La ventaja que tiene este método sobre otros de
reducción de la dimensión radica en la posibilidad de clasificar y representar
un gran número de revistas junto a los departamentos en un espacio
bidimensional.

Descriptores: Préstamo interbibliotecario/Publicaciones

Resumen: Bensman, prior to his own reanalysis of the data, takes an
historical look at the controversy over the apparent conflict between Urquart's
contention that interlibrary loan demand for a journal is a measure of its total
use and Garfield's contention that a small core of highly cited journals will
provide the necessary communication channel for science. In 1976 Garfield's
citation data was compared by Scales to National Lending Library for Science and
Technology's use survey data for 1967 to 1969 excluding any titles not in the
SSCI source journals using the Spearman rank correlation coefficient. It was
necessary to consider 250 titles before 50 common titles occurred and most
correlations were not significant. These results were criticized on the basis
that the lending library's loans were for material typical libraries did not
collect, and were thus unlikely to be for core materials, but Urquart and Line
argued that borrowing was from libraries that were not University libraries but
special libraries that did not buy the core. Line later rejected any generalized
use study whether based on citation or lending as not reflecting unique local
needs. Brooks' statistical analysis of the Scales study pointed out the
inappropriate design and left the question unanswered.

Resumen: This paper reviews the work of the Chemoinformatics Research
Group in the Department of Information Studies at the University of Sheffield,
focusing particularly on the work carried out in the period 1985-2002. Four
major research areas are discussed, these involving the development of methods
for: substructure searching in databases of three-dimensional structures,
including both rigid and flexible molecules; the representation and searching of
the Markush structures that occur in chemical patents; similarity searching in
databases of both two-dimensional and three-dimensional structures; and compound
selection and the design of combinatorial libraries. An analysis of citations to
321 publications from the Group shows that it attracted a total of 3725 residual
citations during the period 1980-2002. These citations appeared in 411 different
journals, and involved 910 different citing organizations from 54 different
countries, thus demonstrating the widespread impact of the Group's
work.

journals that provide 80% of the sample's article citations. The bibliometric
concept of 'success-breeds-success ' is reviewed, and its application to this
sample of journals is quantified. The special problems of defining a core
collection in a multidisciplinary field are discussed. Data is also provided on
the types of publications cited and the age distribution of cited
journals.

Resumen: The Matthew effect for countries (MEC) consists of the
systematic deviation in the number of actual (observed) citations from the
number of expected citations: A few countries, expecting a high impact (i.e., a
high number of cites per paper) receive a surplus of citations, while the
majority of countries, expecting a lower impact, lose citations. The MEC is
characterized by numerous facets, but two are the most impressive. The first is
the possibility of ranking the science nations by their overall efficiency of
scientific performance, thus making the MEC attractive for science policy. The
second is the concentration of the MEC in a small number of scientific journals
which happen to be the most competitive markets for scientific papers and,
therefore, are of interest to librarians as well as scientists.

Resumen: Why devote an ARIST chapter to scholarly communication and bib-
liometrics, and why now? Bibliometrics already is a frequently covered ARIST
topic, with chapters such as that by White and McCain (1989) on bibliometrics
generally, White and McCain (1997) on visualization oflit- eratures, Wilson and
Hood (2001) on informetric laws, and Tabah (2001) on literature dynamics.
Similarly, scholarly communication has been addressed in other ARIST chapters
such as Bishop and Star (1996) on social informatics and digital libraries,
Schamber (1994) on relevance and information behavior, and many earlier chapters
on information needs and uses. More than a decade ago, the first author
addressed the intersection of scholarly communication and bibliometrics with a
journal special issue and an edited book (Borgman, 1990; Borgman & Paisley,
1989), and she recently examined interim developments (Borgman, 2000a, 2000c).
This review covers the decade (1990-2000) since the com- prehensive 1990 volume,
citing earlier works only when necessary to explain the foundation for recent
developments.

conducted in traditional fashion by Howard White and Katherine McCain (1997,
1998), this survey not only reviews emerging techniques in interactive data
analysis and information visualization, but also depicts the bibliographical
structure of the field itself. The chapter starts by reviewing the history of
knowledge domain visualization. We then present a general process flow for the
visualization of knowledge domains and explain commonly used techniques. In
arder to visualize the domain reviewed by this chapter, we introduce a
bibliographic data set of considerable size, which includes articles from the
citation analysis, bibliometrics, semantics, and visualization literatures.
Using tutorial style, we then apply various algorithms to demonstrate the
visualization effects produced by different approaches and compare the
results.

Resumen: Digital libraries stand to benefit from technology
contributions from the fields of information visualization, human-computer
interaction, and cognitive psychology, among others. However, the current state
of interaction between these fields is not well understood. We have used our
knowledge visualization tool, VxInsight®, to provide several domain
visualizations (science maps) of the overlap between these fields. Relevant
articles were extracted from the Science Citation Indexes (SCI and Social SCI)
using keyword searches. An article map, a semantic (co-term) map, and a
co-author network have been generated from the data. Analysis reveals that while
there are overlaps between fields, they are not substantial. However, the most
recent work suggests areas where future collaboration could have a great impact
on digital libraries of the future.

Resumen: CrossRef, the only full-blown application of the Digital Object

started as a cooperative effort among publishers and technologists to prototype
DOI-based linking of citations in e-journals evolved into an independent,
non-profit enterprise in early 2000. We have made considerable headway during
our first year, but there is still much to be done. When CrossRef went live with
its collaborative linking service last June, it had enabled reference links in
roughly 1,100 journals from a member base of 33 publishers, using a functional
prototype system. The DOI-X prototype was described in an article published in
D-Lib Magazine in February of 2000. On the occasion of CrossRef's first birthday
as a live service, this article provides a non-technical overview of our
progress to date and the major hurdles ahead.

Resumen: The use of citation counts to assess the impact of research
articles is well established. However, the citation impact of an article can
only be measured several years after it has been published. As research articles
are increasingly accessed through the Web, the number of times an article is
downloaded can be instantly recorded and counted. One would expect the number of
times an article is read to be related both to the number of times it is cited
and to how old the article is. The authors analyze how short-term Web usage
impact predicts medium-term citation impact. The physics e-print archive -
arXiv.org - is used to test this.

Resumen: Examination of the role of e-prints in physics literature was
conducted by citation analysis. Two databases were analyzed. Citation analysis
was performed on e-prints from the Los Alamos e-print archive, arXiv.org, using
the Stanford Public Information Retrieval System's High Energy Physics
(SPIRES-HEP) and the Institute for Scientific Information's SciSearch databases.
The SPIRES-HEP data represents citations to e-prints by e-prints while SciSearch
data represents citations to e-prints by journal articles. Citations from 1991
to 1999 were examined. E-prints in the SPIRES-HEP database were cited
approximately 10 times each by other e-prints, while those found in SciSearch
were cited approximately 0.5 times each by journal articles. Despite this
difference, the citation patterns were similar for both e-prints and journal
articles. The citation rate by both e-prints and journals was highest from the
high energy particle physics archives. The data from SPIRES-HEP indicates that
e-prints are used to a greater extent by physicists than previously measured and
that e-prints have become an integral and valid component of the literature of
physics.

Descriptores: Comunicación científica/Física /Análisis de

Resumen: To learn how e-prints are cited, used, and accepted in the
literature of physics and astronomy, the philosophies, policies, and practices
of top-tier physics and astronomy journals regarding e-prints from the Los
Alamos e-print archive, arXiv.org, were examined. Citation analysis illustrated
e-prints were cited with increasing frequency by a variety of journals in a wide
range of physics and astronomy fields from 1998 to 1999. The peak e-print
citation rate of 3 years observed was comparable to that of print journals,
suggesting a similarity in citation patterns of e-prints and printed articles.
The number of citations made to 37 premier physics and astronomy journals
and their impact factors have remained constant since arXiv.org's inception in
1991, indicating that e-prints have yet to make an impact on the use of the
printed literature. The degree of acceptance stated by the journals' editors and
the policies given in the journal's instructions to authors sections concerning
the citing of e-prints and subsequent publication of papers that have appeared
as e-prints differed from journal to journal, ranging from emphatically
unacceptable to why not? Even though the use of the traditional literature has
not changed since arXiv.org began and the policies concerning e-print citation
and publication were inconsistent, the number of citations (35,928) and
citations rates (34.1%) to 12 arXiv.org archives were found to be large and
increasing. It is, therefore, evident that arXiv.org e-prints have evolved into
an important facet of the scholarly communication of physics and astronomy.

Resumen: Brown uses 197 e-prints from Elsevier's Chemistry Preprint
Server, CPS, for citation analysis to determine if they are cited in the
chemical literature, as well as surveys of the 116 CPS authors and leading
chemical journal editors ( as shown in Journal Citation Reports) to determine
the use and influence of the e-print in chemistry. The highest
viewed and discussed e-prints in July of 2001 were checked for appearance as
printed papers in December of 2001. Of these, 32% later appeared in the regular
journal literature. The 28% of editors responding, with one exception, did not
accept papers in the CPS or had no policy. On the acceptance of citations to
e-prints, 27% said yes, 36% no, and 36% chose the other category. The 60
responding authors (52%) reported the submission of 1.7 papers to CPS, visit the
site regularly, and 78% indicated they also contribute to peer reviewed
journals. No citations to e-prints were found in the Web of Science from
2000 to 2001. The only citations to CPS documents from CPS documents were two
self citations. While CPS is utilized and valued by its users, it is not
integrated into the web of chemistry citation.

Future Citation Behavior". Journal of the American Society for

Descriptores: Análisis de citas/Conducta
Resumen: Burrell predicts the future citation behavior for sources in an
homogeneous set of papers each having a given number of current citations
with the thought that the estimate of a paper's total future citations is an
indicator of its impact. Each paper is assumed to have a latent rate at which
citations may be acquired which constitutes a random variable over the
collection. Obsolescence is represented by a cumulative distribution function on
time, and the number of total citations at a given time as a Poisson
distribution, the mean of which increases with time to a finite limit. The
distribution of the additional number of citations to a paper during an interval
of time can then be found permitting the computation of an expected total number
of citations. The latent rate distribution may be adequately modeled by the
gamma distribution, leading to a negative binomial distribution for the
conditional distribution of citations, and a proof that the mean number of
additional citations is a linear function of the current number of citations,
which expresses the success breeds success principle. It is also possible to
find the probability that an un-cited paper will be cited in a given time
interval, or that a paper having received a given number of citations will
receive no more in such an interval. It is not totally clear how to estimate the
gamma distribution parameters, and there is currently no empirical evidence to
support the model.

Resumen: Research patterns could enhance understanding of the
Information Systems (IS) field. Citation analysis is the methodology commonly
used to determine such research patterns. In this study, the citation
methodology is applied to one of the top-ranked Information Systems
conferences-international Conference on Information Systems (ICIS). Information
is extracted from papers in the proceedings of ICIS 2000 to 2002. A total of 145
base articles and 4,226 citations are used. Research patterns are obtained using
total citations, citations per journal or conference, and overlapping citations.
We then provide the citation ranking of journals and conferences. We also
examine the difference between the citation ranking in this study and the
ranking of IS journals and IS conferences in other studies. Based on the
comparison, we confirm that IS research is a multidisciplinary research area. We
also identify the most cited papers and authors in the IS research area, and the
organizations most active in producing papers in the top-rated IS conference. We
discuss the findings and implications of the study.

Infurmation Europe Ltd, a UK-based commercial organisation. In order to measure
the impact of these conferences on the library and information science
literature in general, a concept of conference impact factor (CIF) is explored
for the first time. Following the pattern of journal impact factor (JIF), the
study presents a methodology for exploring the characteristics of a core
international conference and measuring its impact. The study used the online
citations databases in DIALOG, as well as the CD-ROM version of Library and
Infonnation Science Abstracts LISA. Through statistical and bibliometric
anaiysis, the paper provides quantitative information about geographic
distribution of members of Organising Committees, Referee Panels, authors,
delegates and citations. Knowledge export of the conference is measured by the
subject categories of citing journals. A list of the top must cited papers of
the Proceedings is presented, as well as the names of the citing authors and

Resumen: The idea of a unified citation index to the literature of
science was first outlined by Eugene Garfield [1] in 1955 in the journal
Science. Science Citation Index has since established itself as the gold
standard for scientific information retrieval. It has also become the database
of choice for citation analysts and evaluative bibliometricians worldwide. As
scientific publication moves to the web, and novel approaches to scholarly
communication and peer review establish themselves, new methods of citation and
link analysis will emerge to capture often liminal expressions of peer esteem,
influence and approbation. The web thus affords bibliometricians rich
opportunities to apply and adapt their techniques to new contexts and content:
the age of ‘bibliometric spectroscopy’ [2] is dawning.

other, or unidentifiable. Web source citations were verified online to see if
they still existed and were classed as: found directly, not found directly but
found elsewhere, found after correcting a typographical error, and not found
(after a site and Google search). The average number of citations increased form
11.6 in 1996 to 11.9 in 1999. The mean number of journals and magazines did not
change significantly. Overall median citations increased form 10 to 12. Book
citations dropped from 30% to 19%, Web citation went from 9% to 21%, and
newspapers increased form 7% to 16%. There was a significant decline in the use
of books and journals in favor of the use of newspapers and magazines
interpreted as a decline in the use of scholarly materials. For 1999 URLs, 55%
went directly to a cited document, 19% were found elsewhere, and 10% contained
errors. 16% were not found. Of the 1996 citations only 18% of the URLs still led
directly to the cited document, 26%were found elsewhere, 3% had errors and 53%
could not be found. The authors believe stricter guidelines for acceptable
citations are called for, as is the creation of scholarly portals, and increased

the association strengths of terms representative of relevant publications or
other texts produced in IR field. Data were collected from Science Citation
Index (SCI) and Social Science Citation Index (SSCI) for the period of
1987¯1997. In addition to the keywords added by the SCI and SSCI databases,
other important keywords were extracted from titles and abstracts manually.
These keywords were further standardized using vocabulary control tools. In
order to trace the dynamic changes of the IR field, the whole 11-year period was
further separated into two consecutive periods: 1987¯1991 and 1992¯1997. The
results show that the IR field has some established research themes and it also
changes rapidly to embrace new themes.

rather informetric artifact. The relationship between the fraction of
multinational publications of a country and the country's fractional score is
also shown to be probabilistic in nature. However, the relationship between the
Price index and median age requires both probabilistic and informetric
explanation, and the cumulative first citation distribution seems best explained
with a curve incorporating Lotka's exponent and thus has high informetric value.

Resumen: Measurement of the degree of interconnectedness in graph like
networks of hyperlinks or citations can indicate the existence of research
fields and assist in comparative evaluation of research efforts. In this
issue we begin with Egghe and Rousseau who review compactness measures and
investigate the compactness of a network as a weighted graph with dissimilarity
values characterizing the arcs between nodes. They make use of a generalization
of the Botofogo, Rivlin, Shneiderman,( BRS ) compaction measure which treats the
distance between unreachable nodes not as infinity but rather as the number of
nodes in the network. The dissimilarity values are determined by summing the
reciprocals of the weights of the arcs in the shortest chain between two nodes
where no weight is smaller than one. The BRS measure is then the maximum value
for the sum of the dissimilarity measures less the actual sum divided by the
difference between the maximum and minimum. The Wiener index, the sum of
all elements in the dissimilarity matrix divided by two, is then computed for
Small's particle physics co-citation data as well as the BRS measure, the
dissimilarity values and shortest paths. The compactness measure for the
weighted network is smaller than for the un-weighted. When the
bibliographic coupling network is utilized it is shown to be less compact than
the co-citation network which indicates that the new measure produces results
that confirm to an obvious case.

Resumen: Purpose - The purpose of this paper is to clarify earlier work
on journal diffusion metrics. Classical journal indicators such as the Garfield
impact factor do not measure the breadth of influence across the literature of a
particular journal title. As a new approach to measuring research influence, the
study complements these existing metrics with a series of formally described
diffusion factors. Design/methodology/approach - Using a publication-citation
matrix as an organising construct, the paper develops formal descriptions of two
forms of diffusion metric: 'relative diffusion factors' and 'journal diffusion
factors' in both their synchronous and diachronous forms. It also provides
worked examples for selected library and information science and economics
journals, plus a sample of health information papers to illustrate their
construction and use. Findings - Diffusion factors capture different aspects of
the citation reception process than existing bibliometric measures. The paper
shows that diffusion factors can be applied at the whole journal level or for
sets of articles and that they provide a richer evidence base for citation
analyses than traditional measures alone. Research limitations/implications -
The focus of this paper is on clarifying the concepts underlying diffusion
factors and there is unlimited scope for further work to apply these metrics to
much larger and more comprehensive data sets than has been attempted here.
Practical implications - These new tools extend the range of tools available for
bibliometric, and possibly webometric, analysis. Diffusion factors might find
particular application in studies where the research questions focus on the
dynamic aspects of innovation and knowledge transfer. Originality/value - This
paper will be of interest to those with theoretical interests in informetric
distributions as well as those interested in science policy and innovation
studies.

Resumen: In this issue we begin with the Frohlich and Resler
report on the evaluation of research productivity at the University of Texas
Institute for Geophysics by bibliometric indicators using a four part
categorization of journals into mainstream, archival, proceedings and other, and
five different journal halflife computations. Halflife computations are drawn
from work on earthquakes, which like citations do not decay strictly
exponentially, requiring formulations avoiding such features. Weighting to
emphasize points with more numerous and reliable data seem called for in both
instances, and in both the discrete period of reporting can bias the results.
This implies ignoring very high and low magnitude data as found in the first
year or two of citation and data older than some point, weighting data with more
observations more strongly when fitting, and perhaps correcting for the interval
problem. A sequence of rates by year will yield a median age of citation, or by
dividing 10 log2 by the difference in the logs of two rates, commonly the second
and twelfth year rates, a two point halflife. If one determines the slope of the
same 11 points, weighting each number by the number of articles used to
determine the rate, a negative log2 divided by this slope will provide a
weighted least squares halflife. If the sum of the products of the rates and
their times in years is divided by the sum of the rates we get a rate averaged
time and the maximum likelihood half life is natural log2 times the difference
between the rate average time and the minimum rate time. This relatively easily
computed method is in common use in earthquake analysis. A ratio method is also
possible where the sum of the rates for a given period of years are divided by
the sum of the rates for an equal period of years following.

Resumen: Purpose - This paper seeks to address the question: should the
world's top universities be led by top researchers, and are they?
Design/methodology/approach - The lifetime citations are counted by hand of the
leaders of the world's top 100 universities identified in a global university
ranking. These numbers are then normalised by adjusting for the different
citation conventions across academic disciplines. Two statistical measures are
used - Pearson's correlation coefficient and Spearman's p. Findings - This study
documents a positive correlation between the lifetime citations of a
university's president and the position of that university in the global
ranking. Better universities are run by better researchers. The results are not
driven by outliers. That the top universities in the world - who have the widest
choice of candidates L systematically appoint top researchers as their vice
chancellors and presidents seems important to understand. This paper also shows
that the pattern of presidents' life-time citations follows a version of Lotka's
power law. Originality/value - There are two main areas of contribution. First,
this paper attempts to use bibliometric data to address a performance-related
question of a type not seen before (to the author's knowledge). Second, despite
the importance of research to research universities - as described in many
mission-statements - no studies currently exist that ask whether it matters if
the head of a research university is himself or herself a committed researcher.
Given the importance of universities in the world, and the difficulty that many
have in appointing leaders, this question seems pertinent.

Resumen: A citation analysis of dissertations accepted in the Department
of Chemistry at The Ohio State University between 1996-2000 was performed as a
way to determine material use. The 30 dissertations studied generated a total of
3,704 citations. Types of materials cited, currency of literature, and
dissertation topics were all analyzed. The current results corroborate past
research by other authors. Journal articles were cited more frequently than
monographs: 85.8% of the citations were journal articles and 8.4% of the
citations were monographs. The results of this study may be used to assist OSU
and other universities in chemistry collection development.

Resumen: The Web is revolutionizing the entire scholarly communication
process and changing the way that researchers exchange information. In this
paper, we analyze two views of information production and use in
computer-related research based on citation analysis of PDF and Postcript
formatted publications on the Web using autonomous citation indexing (ACI), and
a parallel citation analysis of the journal literature indexed by the Institute
for Scientific Information (ISI) in SCISEARCH. Our goal is to establish a
baseline profile of computer science 'literature' as it appears in the published
journals and as it appears on the publicly available Web. From this starting
point, we hope to identify additional research areas dealing with information
dissemination and citation practices in computer science and the utility of
autonomous citation indexing on the Web as an adjunct to commercial
indexing

Resumen: The very nature of scholarly research has fundamentally changed
with the increased availability of reference or citation linking. With the
ubiquity of the Web, it seems natural to users and information professionals
alike that they be able to link painlessly among full-text articles, abstracting
and indexing (A&I) bibliographic information, and article reference lists.
In a perfect world, such linking would occur seamlessly. However, in reality,
technical obstacles, as well as organizational concerns, blur the vision of
perfect, seamless reference linking. Information professionals need to be aware
of the technical and organizational interests and obstacles associated with
reference linking in order to better serve their users.

Resumen: In this article the first-citation process is
investigated. Former studies led to two double exponential models for this
process. The first model resulted in a concave function, the other one in a
function with an inflection point (an S-shaped function). Real data using a year
as time unit could best be described by the first model, data using two weeks as
a unit could best be described by the second one. In this note we show that for
a group of nine related data sets in the field of population genetics, using one
year as a unit, the first observation is confirmed: the concave model can
adequately describe such data.

Resumen: This study assesses the ways in which citation searching of
scholarly print journals is and is not analogous to backlink searching of
scholarly e-journal articles on the WWW, and identifies problems and issues
related to conducting and interpreting such searches. Backlink searches are
defined here as searches for Web pages tat link to a given URL. Backlink
searches were conducted on a sample of 39 scholarly electronic journals. Search
results were processed to determine the number of backlinking pages, total
backlinks, and external backlinks made to the e-journals and to their
articles. The results were compared to findings from a citation study
performed on the same e-journals in 1996. A content analysis of a sample of the
files backlinked to e-journal articles was also undertaken. The authors identify
a number of reliability issues associated with the use of 'raw' search engine
data to evaluate the impact of electronic journals and articles. No correlation
was found between backlink measures and ISI citation measures of e-journal
impact, suggesting that the two measures may be assessing something quite
different. Major differences were found between the types of entities that cite,
and those that backlink, e-journal articles, with scholarly works comprising a
very small percentage of backlinking files. These findings call into question
the legitimacy of using backlink searches to evaluate the scholarly impact of
e-journals and e-journal articles (and by extension, e-journal authors).

Resumen: The reference lists of forty-three education
dissertations on curriculum and instruction completed at the University of
Minnesota during the calendar years 2000-2002 were analyzed to inform collection
development. As one measure of use of the academic library collection, the
citation analysis yielded data to guide journal selection, retention, and
cancellation decisions. The project aimed to ensure that the most frequently
cited journals were retained on subscription. The serial monograph ratio for
citation also was evaluated in comparison with other studies and explored in the
context of funding ratios. Results of citation studies can provide a basis for
liaison conversations with faculty in addition to guiding selection decisions.
This research project can serve as a model for similar projects in other
libraries that look at literature in education as well as other
fields.

Initiative
Resumen: The speed of scientific communication the rate of ideas
affecting other researchers' ideas is increasing dramatically. The factor
driving this is free, unrestricted access to research papers. Measurements of
user activity in mature eprint archives of research papers such as arXiv have
shown, for the first time, the degree to which such services support an evolving
network of texts commenting on, citing, classifying, abstracting, listing and
revising other texts. The Open Citation project has built tools to measure this
activity, to build new archives, and has been closely involved with the
development of the infrastructure to support open access on which these new
services depend. This is the story of the project, intertwined with the
concurrent emergence of the Open Archives Initiative (OAI). The paper describes
the broad scope of the project's work, showing how it has progressed from early
demonstrators of reference linking to produce Citebase, a Web-based citation and
impact-ranked search service, and how it has supported the development of the
EPrints.org software for building OAI-compliant archives. The work has been
underpinned by analysis and experiments on the semantics of documents (digital
objects) to determine the features required for formally perfect linking
instantiated as an application programming interface (API) for reference
linking that will enable other applications to build on this work in
broader digital library information environments.

Resumen: Van Hooydonk notes that a large part of the observed
impact factor of a journal, or impact of a discipline, is dependent on the
number of publications therein. If we use the number of publications on a topic
to predict an expected impact factor, the ratio of the observed factor to the
expected factor can be used to provide a topically relative impact measure. In
the 55 sub-disciplines of science in the Institute of Scientific Information
database about 80% of the impact factor is correlated with disciplinary
publication level. The removal of disciplinary differences leads to changed
journal rankings, which should better indicate quality of research.

Resumen: Hyland examines self referencing practices by analyzing
their textual uses in 240 randomly chosen research papers and 800 abstracts
across 80 expert selected journals from 1997 and 1998 in eight disciplines, as a
key to their author's assumptions as to their own role in the research process
and to the practices of their disciplines. Scanned texts produced a corpus of
nearly 1.5 million words which was searched using WordPilot for first person
pronouns and all mentions of an author's previous work. There were 6,689
instances of self reference in the papers and 459 in the abstracts; on the
average 28 cases per paper, 17% of which were self citations. There was one self
mention in every two abstracts. Nearly 70% of self reference and mention
occurred in humanities and social science papers, but biologists employed the
most self citation overall and 12% of hard science citations were found to be
self citations. Interviews indicated that self citation was deemed important in
establishing authority by fitting oneself into the research framework. Self
mention arises in four main contexts: stating the goal or the structure of the
paper, explaining a procedure, stating results or a claim, and elaborating an
argument.

Descriptores: Ciencias sociales/Análisis de citas/Producción científica
/Bibliometría/Indicadores/Social citation index
Resumen: The paper investigates the advantages of graphical mapping of
national research publication and citation profiles from scientific fields in
order to provide additional information with respect to research performance. By
means of multi-dimensional scaling techniques national social science profiles
from seventeen OECD countries and two periods, 1989-1993 and 1994-1998, are
mapped, each profile represented by a vector of either publication volumes or
citation values for nine social science fields. Aside from demonstrating the
developments of publication volumes and citedness ranges as well as patterns,
the graphical maps display clusters and similarities of national profiles over
time. Combined with international rankings of averaged national impact factors
(NIF) relative to the average world impact of field (WIF) for the same number of
fields and periods, the graphical display supplies additional otherwise
concealed information of the differences in research patterns between countries
- even when the NIFs are quite similar. The analyses show that low Pearson
correlation coefficients can be applied to flag extraordinary instances of
either high or low national citation impacts during a period. Most importantly,
the graphical maps make a strong case for adjusting or tuning the baseline
impact to the actual national publication profiles when comparing NIFs of
different countries. A new indicator, the Tuned Citation Impact Index (TCII) is
proposed. It is constructed from the amount of expected citations a country
ought to have received in each research field aggregated over its true profile.
Common baseline profiles, like those of the world or EU, are consequently not
regarded as the ideal benchmark.

Resumen: Texas Tech University is a part of the Texas State University
System which opened its doors in 1925. The current enrollment is about 24,000
dispersed among six colleges. The Mathematics Department is one of thirteen in
the College of Arts and Sciences with a Ph.D. program. One of those programs is
in statistics. Seven faculty members were identified from that program. Their
contribution to published research for 1993 and the first half of 1994 was
collected and a citation analysis was conducted and subsequently applied to the
collection development process at the University Library, where distinct
discipline based collection development policies are now being formulated. Two
citation patterns were identified: bibliographic and non-bibliographic
citations. Bibliographic citations (from the bibliography) numbered 394 from 122
titles. Journals and monographs were the two formats most frequently cited,
46.7% and 36.9%, respectively. The average age of a citation was 12.3 years. The
two most frequently cited journal titles were: Journal of Time Series Analysis
and Stochastic Processes and Their Applications. Non-bibliographic citations
(not found in the bibliography) were used to identify the more important
research topics to this population of faculty: Hermitian operators, Appel
polynomials, Laplace transform, Euclidean space, Drichlet polynomials, Lebesgue
measure, Hilbert space, and Taylor expansion. Since the conclusion of this
study, the most frequently cited journals and monographs have been acquired or
recommended for acquisition in conjunction with the Library's collection
development policy for Mathematics.

The purpose of this study is to characterize the citation patterns of the
interdisciplinary field of environmental and human health as compared with other
disciplines and to apply the results to collection development. Twenty-four
articles were selected from 1996 and 1997 with over 1600 citations to more than
950 listed references. The average age of citations was 10.5 years for
journals and 9.4 years for books. On average, journals were cited 67% of the
time while books were cited 17% of the time. Proceedings, theses, and technical
reports were also cited but that data was not applied to collection development.
The impact on collection development has been to identify a small number of
specific books which were frequently cited but were not in the collection and to
identify important subject terms with which to guide the selection of related
books. Finally, 12 new subscriptions to frequently.

it is important for librarians with humanities collection development
responsibilities to consider each field separately when making collection
development decisions. The authors investigated the language of sources cited in
each field. Foreign language citations continue to be dominated by French and
German. This study also confirms that, in most humanities disciplines,
monographs remain the dominant format of cited sources, although some fields

Descriptores: Duplicación de registros/Análisis de citas
Resumen: Four cases, illustrated by four examples, of duplicate or
highly related publications can be distinguished and are analyzed here using
citation data obtained from the Science Citation Index (SCI): (1) publication by
different authors in the same journal; (2) the same author(s) publishing in
different journals; (3) publication by different authors in different journals;
(4) the same author(s) publishing highly related papers simultaneously in the
same journal, often as part of a series of papers. Example 1, illustrating case
1, is an occurrence of highly related publications in mechanistic organic
chemistry. Example 2, from analytical organic chemistry, contains elements of
cases 2 and 3. Example 3, dealing solely with case 3, discusses two time-delayed
publications from analytical biochemistry, which were highlighted by Garfield
several times in the past to show how the SCI could be utilized to avoid
duplicate publication. Example 4, derived from synthetic organic chemistry
(total syntheses of taxol), contains elements of cases 1, 3, and 4 and, to a
lesser extent, case 2. The citation records of the highly related or duplicate
publications can deviate considerably from the journal impact factors; this was
observed in three of the four examples relating to cases 2, 3, and 4. The
examples suggest that citation of a paper may depend significantly on the
journal in which it is published. As an indicator of this dependence, the
journals in which the papers used in the present examples appeared were
examined. Other factors such as key words in the paper title may also play a
role.

Resumen: In order to determine the impact of specific published research
on varied disciplines and to determine research user characteristics, Kostoff,
et alia, test the viability of analyzing the free text fields of about 300
Science Citation Index records of papers that cited a fundamental paper on sand
pile vibration. Abstracts were collected and a taxonomy of phrases and terms was
created by manually analyzing the single words, word pairs and word triples
extracted from the records. The same phrases were automatically clustered by the
Mutual Information Index (co-occurrence frequency over the squared product of
frequencies) for the high frequency phrases; and for the low frequency phrases
those phrases associated with each high frequency phrase whose co-occurrence
divided by its total occurrence exceeded .5. Extra-discipline basic research
papers range from 15% to 25% of total citing papers each year with no evident
latency period. There is a four year latency period for applications
papers.

Resumen: The aggregated journal-journal citation matrix derived from
Journal Citation Reports 2001 can be decomposed into a unique subject
classification using the graph-analytical algorithm of bi-connected components.
This technique was recently incorporated in software tools for social network
analysis. The matrix can be assessed in terms of its decomposability using
articulation points which indicate overlap between the components. The
articulation points of this set did not exhibit a next-order network of 'general
science' journals. However, the clusters differ in size and in terms of the
internal density of their relations. A full classification of the journals is
provided in the Appendix. The clusters can also be extracted and mapped for the
visualization.

Resumen: The concept of ‘modes of knowledge production’ was used by
Gibbons et al. (1994) [1] to distinguish between transdisciplinary (‘Mode 2’)
R&D and more traditional (‘Mode 1’) research. This paper explores whether
the Internet provides a means to operationalize ‘Mode 2’ knowledge production as
containing a differently codified communication pattern which can be compared to
co-word and citation patterns in scientometric databases (‘Mode 1’). Innovations
on the drugs market, for example, can be indicated at the commercial end by
using the trade names of the drugs (e.g., Evista), while the very same
innovation can be retrieved in the patent and science citation databases using
the generic names of the active substances involved (in this case, raloxifene).
By using the generic names the new drugs can be traced back into their
respective knowledge bases.

Resumen: The aggregated citation relations among journals included
in the Science Citation Index provide us with a huge matrix, which can be
analyzed in various ways. By using principal component analysis or factor
analysis, the factor scores can be employed as indicators of the position of the
cited journals in the citing dimensions of the database. Unrotated factor scores
are exact, and the extraction of principal components can be made stepwise
because the principal components are independent. Rotation may be needed for the
designation, but in the rotated solution a model is assumed. This assumption can
be legitimated on pragmatic or theoretical grounds. Because the resulting
outcomes remain sensitive to the assumptions in the model, an unambiguous
classification is no longer possible in this case. However, the factor-analytic
solutions allow us to test classifications against the structures contained in
the database; in this article the process will be demonstrated for the
delineation of a set of biochemistry journals.

Resumen: All libraries have to make decisions on what to acquire and
what to dispose of. For books, there are few useful statistical aids. For
journals, the most valid measure of what to continue or cease acquiring is
actual usage; for what new to acquire, demand from and use of other sources
provide some useful data. Citation data have been advocated as a surrogate
for use data, and are much easier to collect. However, in spite of a good
general correlation between citations and supralibrary use, they have to be used
with caution in individual libraries, and are of little help in with marginal
decisions. Once data are collected, the most valid measure for purchase
decisions is the number of uses per unit of cost per journal per year; for
disposal decisions, use per unit of shelf space occupied. Data collection, which
can be confined to journals that are not clear purchases, can be done by a
variety of methods. In the future, if articles become the key unit rather than
journals, the identification of most used articles might prove to have some
practical value. A set of studies comparing uses with citations and other
possible surrogates would be desirable.

Resumen: Using the 1996 Journal Citation Reports and the
1992 to 1998 issues of six journals suggested by a software engineer and
supplemented with a journal focused on the objectoriented approach, Marion and
McCain identified parent journals providing 25% of the cites by the seed journal
authors, and child journals that generated 50% of cites to the seed group.
Other candidate core lists came from journals frequently indexed by a set of
INSPEC Thesaurus terms and codes, derived by ranking the terms and codes used to
describe the papers in the seed journals and collecting two groups, each of
whose disjunction was searched on the INSPEC database and the resulting journal
lists ranked as to frequency. The associated codes, intersected with the term
``software engineering'' were also searched, and the titles ranked, to produce
two more candidate lists. The union of all the JCR journals and the top twenty
on each INSPEC list yielded 32 journals. Cocitation counts were collected and
journals retained with a mean cocitation rate of seven or more.

Resumen: Purpose - The purpose of this article is to describe Maurice
Line ' s continuing interest in bibliometrics and in its possible application to
library problems since the 1970s. He has especially emphasized two strands. One
is the concept of obsolescence and how it applies in practice. The other is
citation studies of the social sciences, which tend to have been ignored in
comparison with the sciences. He has particularly explored the limitations that
need to be taken into account when trying to apply bibliometric ideas in
practical contexts. Design/methodology/approach - An analysis of Line ' s
publications on bibliometrics led to a selection of major themes in his
writings. A subsequent study of the publications of others who wrote on this
topic over the same period provided a framework for assessing his work. Findings
- Maurice Line played an important role in the development of this area of
bibliometrics, though he slightly modified some of his early ideas as time has
passed. Originality/value - Provides a background to Maurice Line ' s interest
in bibliometrics since the 1970s.

Resumen: The 1960s saw the birth of what is now called 'scientometrics'.
One of the queries that arose then related to citations of previous literature.
Was recent literature cited proportionately more than older literature? Studies
by Price, along with that reprinted here, seemed to indicate that the answer was
'yes'. This 'immediacy effect', as it was labelled, could be measured in
quantitative terms, but how to do so required some thought. For example, what
was the best form of index for representing immediacy, and what errors were
involved in estimating the effect? Discussions of the usage of past literature
could have practical implications for libraries. One question, therefore, was
what implications, if any, citation studies had for the provision of journals to
library users. On the scientometrics side, there were such questions as why an
immediacy effect occurred and to what extent it could be discerned in different
subject areas. This article surveys attempts to examine questions like these
over the period from the 1960s to the present day, updating an article published
in Journal of Documentation in 1967.

Resumen: This research is a part of ongoing study to better understand
citation analysis on the Web. It builds on Kleinberg's research (J. Kleinberg,
R. Kumar, P. Raghavan, P. Rajagopalan, A. Tomkins, Invited survey at the
International Conference on Combinatorics and Computing, 1999) that hyperlinks
between web pages constitute a web graph structure and tries to classify
different web graphs in the new coordinate space: out-degree, in-degree. The
out-degree coordinate is defined as the number of outgoing web pages from a
given web page. The in-degree coordinate is the number of web pages that point
to a given web page. In this new coordinate space a metric is built to classify
how close or far are different web graphs. Kleinberg's web algorithm (J.
Kleinberg, Proceedings of the ACM-SIAM Symposium on Discrete Algorithms, 1998,
pp. 668¯677) on discovering 'hub web pages' and 'authorities web pages' is
applied in this new coordinate space. Some very uncommon phenomenon has been
discovered and new interesting results interpreted. This study does not look at
enhancing web retrieval by adding context information. It only considers web
hyperlinks as a source to analyze citations on the web. The author believes that
understanding the underlying web page as a graph will help design better web
algorithms, enhance retrieval and web performance, and recommends using graphs
as a part of visual aid for search engine designers.

tool that generates networks of links within and across hyper-textbooks through
a completely automatic and unsupervised procedure is described. The design is
based on statistical techniques. The overall methodology is presented together
with the results of a case study reached through a working prototype that shows
that connecting hyper-textbooks is an efficient way to provide an effective

Resumen: Statistical relationships between downloads from ScienceDirect
of documents in Elsevier's electronic journal Tetrahedron Letters and citations
to these documents recorded in journals processed by the Institute for
Scientific Information/Thomson Scientific for the Science Citation Index (SCI)
are examined. A synchronous approach revealed that downloads and citations show
different patterns of obsolescence of the used materials. The former can be
adequately described by a model consisting of the sum of two negative
exponential functions, representing an ephemeral and a residual factor, whereas
the decline phase of the latter conforms to a simple exponential function with a
decay constant statistically similar to that of the downloads residual factor. A
diachronous approach showed that, as a cohort of documents grows older, its
download distribution becomes more and more skewed, and more statistically
similar to its citation distribution. A method is proposed to estimate the
effect of citations upon downloads using obsolescence patterns. It was found
that during the first 3 months after an article is cited, its number of
downloads increased 25% compared to what one would expect this number to be if
the article had not been cited. Moreover, more downloads of citing documents led
to more downloads of the cited article through the citation. An analysis of
1,190 papers in the journal during a time interval of 2 years after publication
date revealed that there is about one citation for every 100 downloads. A
Spearman rank correlation coefficient of 0.22 was found between the number of
times an article was downloaded and its citation rate recorded in the SCI. When
initial downloads - defined as downloads made during the first 3 months after
publication - were discarded, the correlation raised to 0.35. However, both
outcomes measure the joint effect of downloads upon citation and that of
citation upon downloads. Correlating initial downloads to later citation counts,
the correlation coefficient drops to 0.11. Findings suggest that initial
downloads and citations relate to distinct phases in the process of collecting
and processing relevant scientific information that eventually leads to the
publication of a journal article.

Resumen: Purpose - The purpose of this paper is to propose a multiple
set of journal evaluation indicators using methods and theories from author

image. Design/methodology/approach - The Journal of Documentation is celebrating
its 60th anniversary, and for that reason it is portrayed in a bibliometric
study using the two indicators, based, e.g. on analyses of references in journal
articles and journal co-citation analyses. Findings - The Journal of
Documentation, which is portrayed in this study is characterized by high impact
and high visibility. It publishes a relatively low number of documents with
scientific content compared to other journals in the same field. It reaches far
into the scientific community and belongs to a field that is more and more
visible. The journal is relatively closely bounded to Western Europe, which is
an increasing tendency. Research limitations/implications - The research is
based on analyses of just three LIS journals. Practical implications - journal
citation identity and the journal citation image indicators contribute in giving
a more detailed multifaceted picture of a single journal. Originality/value -
The multiple set of indicators give rise to a journal evaluation of a more
qualitative nature.

Resumen: A citation study of the 692 staff that makes up unit of
assessment 58 (archaeology), in the 2001 UK Research Assessment Exercise (RAE)
was undertaken. Unlike earlier studies, which were obliged to make assumptions
on who and what had been submitted for assessment, these were, for the first
time available from the RAE Web site. This study, therefore, used the specific
submission details of authors and their publications. Using the Spearman
rank-order correlation coefficient, all results showed high statistically
significant correlation between the RAE result and citation counts. The results
were significant at 0.01 per cent. The findings confirm earlier studies. Given
the comparative cost and ease of citation analysis, it is recommended that,
correctly applied, it should be the initial tool of assessment for the RAE.
Panel members would then exercise their judgement and skill to confirm final
rankings.

Resumen: A total of 4,012 citations in 70 postgraduate dissertations in
education submitted to the Delta State University Library between 1992 and 2002
were studied. Most post graduate students in education used more textbooks (60.3
per cent), than other forms of library materials. Four of the top ranked
journals, including the most popularly used - the West African Journal of
Education (WAJE) - are available in the library. A total of 12 (66.7 per cent)
of the 18 most popularly used journals are US publications, thus creating the
need for Delta State University Library to improve on its local journal
collection. Of the 18 most cited journals, six (33.3 per cent) ranked among the
list of significant journals in the field of education.

Resumen: References are at the heart of scholarly journal publishing and
therefore reference links are seen as an essential feature of online scholarly
journals. Scholarly publishers created CrossRef, run by the non-profit
Publishers International Linking Association, Inc., in order to make broad-based
linking efficient and scalable across a wide range of primary publishers,
secondary publishers, abstracting and indexing services, and libraries. CrossRef
runs a system that enables publishers to assign unique identifiers -- Digital
Object Identifiers (DOI) -- to articles and collects standardized metadata so
that the identifiers can be retrieved using bibliographic data. Once the DOI for
an article is known, a persistent link to the full-text article can be created.
CrossRef is a milestone for the scholarly information industry.

Resumen: We report on our findings regarding authors' use of theory in
1,160 articles that appeared in six information science (IS) journals from
1993-1998. Our findings mdicate that theory was discussed in 34.1% of the
articles (0.93 theory incidents per article; 2.73 incidents per article when
considering only those articles employing theory). The majority of these
theories were from the social sciences (45.4%), followed by IS (29.9%), the
sciences (19.3%), and humanities (5.4%). New IS theories were proposed by 71
authors. When compared with previous studies, our results suggest an increase in
the use of theory within IS. However, clear discrepancies were evident in terms
of how researchers working in different subfields define theory. Results from
citation analysis indicate that ES theory 15 not heavily cited outside the
field, except by IS authors publishing in other literatures. Suggestions for
further research are discussed.

Resumen: Generally speaking, the three-year synchronous impact
factor is larger than the two-year one. This follows from theoretical models
derived from observations based on ISIÒs database. In this article we present an
exception to this general rule, based on data from the Chinese Science Citation
Database (CSCD). In 1998 42% of this databaseÒs source journals did not follow
the expected trend. As a possible explanation we note that, contrary to
intuition, in the CSCD the changes in the number of both publications and
citations are largely independent. It is, however, not ruled out that the
observed discrepancies are nothing but statistical fluctuations of the basic
publication-citation model.

Resumen: The term author co-citation is defined and classified according
to four distinct forms: the pure first-author co-citation, the pure author
co-citation, the general author co-citation, and the special
co-author/co-citation. Each form can be used to obtain one count in an author
co-citation study, based on a binary counting rule, which either recognizes the
co-citedness of two authors in a given reference list (1) or does not (0). Most
studies using author co-citations have relied solely on first-author co-citation
counts as evidence of an author's oeuvre or body of work contributed to a
research field. In this article, we argue that an author's contribution to a
selected field of study should not be limited, but should be based on his/her
complete list of publications, regardless of author ranking. We discuss the
implications associated with using each co-citation form and show where simple
first-author co-citations fit within our classification scheme. Examples are
given to substantiate each author co-citation form defined in our
classification, including a set of sample DialogTM searches using references
extracted from the SciSearch database.

increasing number of investigations that examines the growing practice of
authors citing URLs (Uniform Resource Locators) in their publications to support
and argue their scholarly research. It was found that some 46% of all citations
to Web-located sources could not be accessed - with the HTTP 404 (Page not
found) message (61.5%) being the greatest cause of missing citations.
Collectively, the missing citations accounted for 22.0% of all citations, which
represents a significant reduction in the theoretical knowledge base
underpinning many scholarly articles. It is argued that the consequences of
disappearing Web-located citations has led to diminishing opportunities for
future researchers to examination the underlaying foundations of discourse and
argument in scholarly articles.

Resumen: This paper reports the results of a bibliometric analysis of
scholarly journals in the field of psychology. The Impact Factors of a sample of
journals have been collected from Journal Citation Reports (JCR) provided by
ISI. Changes in the Impact Factors were monitored annually over two periods,
1994-1995 and 2000-2001, the years before and after electronic journals
appeared. The collected Impact Factors of scholarly journals from these two
periods are compared in the available media. As a result, it is found that
Impact Factors of 2000 and 2001 were significantly higher than those of 1994 and
1995 in the journals published by parallel publishing (combination
journals-simultaneous publication of paper and electronic journals). In
particular, the Impact Factors of the combination journals increased after the
journals transformed their available media from paper journals to combination
ones. By contrast, in the case of paper journals, there was no significant
difference betweenthe Impact Factors of 1994 and 1995 and those of 2000 and
2001. Additionally, it is possible to infer from later analyses that the
citation rate is not changed by the available media in the authoritative
journals which have comparatively high Impact Factors. In journals with low
Impact Factors, on the other hand, the available media influences the citation
rate.

index
Resumen: The journal impact factors, published by the Institute for
Scientific Information (ISI; Philadelphia, PA), are widely known and are used to
evaluate overall journal quality and the quality of the papers published
therein. However, when making comparisons between subject fields, the work of
individual scientists and their research institutions as reflected in their
articles' ISI impact factors can become meaningless. This inequality will remain
as long as ISI impact factors are employed as an instrument to assess the
quality of international research. Here we propose a new mathematical index
entitled Impact Factor Point Average (IFPA) for assessment of the quality of
individual research work in different subject fields. The index is established
based on a normalization of differences in impact factors, rankings, and number
of journal titles in different subject fields. The proposed index is simple and
enables the ISI impact factors to be used with equality, especially when
evaluating the quality of research work in different subject fields.

Resumen: The use of the phrase ``and the references therein'' within

2,662-paper sample which exhibited ICR. The contributions of the regular and
letter journals were treated separately as were short communications. For each
paper the number of references, the number of references per page, and the
number of works cited with ICR, were noted. All three characteristics vary
widely over the population. There is only a medium positive correlation between
absolute reference use and the intensity of ICR use in the full population and
this weakens when letters alone are considered. The papers from the normal
journal portion of the population determine the correlation in the total
population and the degree to which papers are documented does not correlate with
the intensity of ICR. These variables are independent although both depend upon
the subjective decisions of the referencing author.

Resumen: In the author's previous article (JASIS, 50, [1999], 1284-1294)
it was shown that the quantity of nonindexed indirect-collective references in
the representative elite general physics journal, The Physical Review, now alone
exceeds many times over the quantity of references taken into account by the ISI
as citations and listed in the Science Citation Index. The present article
reports the findings of a new ICR investigation carried out in a representative
sample of the elite journal literature of physics: in the January 1997 issue of
44 source journals covering the domain of physics, i.e., in 2,662 scientific
communications of 38 normal and 6 letter journals. The methods of the
investigation were most rigorous, and consequently, only the indisputable
minimum of the literature phenomenon examined was revealed. It is demonstrated
that the ICR phenomenon is present in all source journals processed of
bibliometrically very heterogeneous nature, in both the normal and the
letter journals. The frequency of the generally occurring ICR phenomenon is very
high: it is found in 17.2% of the sample. There is very little scattering in the
rate of frequency: it is 17.0% in the group of normal journals and 17.9% in the
letter journals. The bibliometrically very heterogeneous representative sample
is very homogeneous regarding the presence and frequency of the ICR phenomenon.
On the basis of these facts it can be stated that the quantity of nonindexed

"Cultural Context and its Impact on Requirements Elicitation in
Thailand". The Electronic Journal of Information Systems in
Developing Countries , Vol. 1, 2000. http://www.is.cityu.edu.hk/research/ejisdc/vol1/v1r2.pdf
Descriptores: Análisis de citas/Internet/Asia/Tailandia
Resumen: This paper reports one part of an ethnographic study of how
software analysts in Thai software houses undertake the requirements engineering
process. In this paper the impact of Thai culture on the elicitation of
requirements in information systems developed will be reported. The important
role of requirements for software and systems development can be traced to the
early study of software engineering. Software developers realised that errors
during the requirements phase caused high cost in fixing systems and often led
to rejection of systems (Laudon and Laudon 1995). This paper compares the nature
of elicitation of requirements by systems analysts in Thailand with standard
descriptions of elicitation in requirements engineering research. Detailed
descriptions of elicitation processes and an evaluation of text are used to
suggest that elicitation in Thailand is affected by different use of analytical
and elicitation tools, different adaptation of those tools to the elicitation
process, an inability to gain full access to all users where requirements can be
identified, increased time needed to uncover requirements and an inability to
develop requirements specification. This has important implications for Software
Houses using western consultants or organisations employing consultants not
familiar with Thai Culture. Understanding the nature of the impact of Thai
culture on Requirements engineering processes should ensure that project failure
due to poor understanding of requirements for systems would be lessened.

para el estudio del uso y las necesidades de información por parte de los
investigadores como usuarios de bibliotecas. Una vez comparados los estudios
locales basados en las publicaciones de los usuarios potenciales de una
biblioteca con los estudios de análisis de citas basados en la bibliografía
circulante a nivel internacional o nacional, se analizan las diferentes fuentes
a partir de las cuales se pueden extraer y estudiar las referencias
bibliográficas citadas por los autores estudiados a nivel local. Como un método
indirecto para los estudios de usuarios y de uso de información, el análisis de
citas es un método eficiente que no interfiere el comportamiento del colectivo
estudiado, y que permite obtener un nivel de detalle en la información obtenida
difícilmente comparable con el que se consigue por otros métodos.

Descriptores: Análisis de citas/Bibliometría
Resumen: Finally, Van den Besselaar comments on Leydesdorff and
Heimeriks' JASIST article that found a relationship between words in titles and
the region of origin of documents by discriminant analysis using title word sets
to predict the region of production in 78% of the cases in a Biotechnology
literature. Van den Besselaar repeats the method with an information science and
a science and technology literature finding an even higher percentage of correct
classification. He then points out that the data used do not meet the conditions
for discriminant analysis in that the independent variables are nominal rather
than on an interval scale, which has the effect, because of the near uniqueness
of the words, of making it trivial to find a relationship with any
classification. Indeed, random groupings of the Biotechnology documents can
equally well be predicted. Testing random splits of the database yields strong
prediction for the first half, but less than the a priori probabilities on the
second half, implying every test results in a different model and the relation
of region to word use needs to be rejected.

Resumen: The number and type of Web citations to journal articles in
four areas of science are examined: biology, genetics, medicine, and
multidisciplinary sciences. For a sample of 5,972 articles published in 114
journals, the median Web citation counts per journal article range from 6.2 in
medicine to 10.4 in genetics. About 30% of Web citations in each area indicate
intellectual impact (citations from articles or class readings, in contrast to
citations from bibliographic services or the author's or journal's home page).
Journals receiving more Web citations also have higher percentages of citations
indicating intellectual impact. There is significant correlation between the
number of citations reported in the databases from the Institute for Scientific
Information (ISI, now Thomson Scientific) and the number of citations retrieved
using the Google search engine (Web citations). The correlation is much weaker
for journals published outside the United Kingdom or United States and for
multidisciplinary journals. Web citation numbers are higher than ISI citation
counts, suggesting that Web searches might be conducted for an earlier or a more
fine-grained assessment of an article's impact. The Web-evident impact of
non-UK/USA publications might provide a balance to the geographic or cultural
biases observed in ISI's data, although the stability of Web citation counts is
debatable.

Descriptores: Análisis de citas
Resumen: White responds to a previously published criticism of the use
of Pearson's r as similarity measure in author co-citation analysis which
suggested that r over responds to dissimilarity when a second group of authors
with minimal co-citation to an initial group is combined with that group. Cosine
and chi square were suggested as replacements. The criticism appears to focus on
the simultaneous study of disjoint literatures, which seems an unlikely
circumstance. Large blocks of cells with zero co-citation will destabilize
Pearson's r but such have not appeared in actual data and are likely only do so
when author-pairs are chosen for lack of co-citation or a less than cohesive set
of authors has been chosen rather than a literature. Using the disjoint data
with Pearson's r, the cosine measure and chi square, multidimensional scaling
and hierarchical clustering routines yield maps that are all very similar.

Resumen: John Swales's 1986 article 'Citation analysis and discourse
analysis' was written by a discourse analyst to introduce citation research from
other fields, mainly sociology of science, to his own discipline. Here, I
introduce applied linguists and discourse analysts to citation studies from
information science, a complementary tradition not emphasized by Swales. Using
replicable biblio-metric techniques, I show that interdisciplinary ties have
grown among citation researchers from discourse analysis, sociology of science,
and information science in the years since Swales wrote. Key authors, journals,
articles, and books are presented in tables based on cocitation data from the
Institute for Scientific Information. While theoretical integration of the
different strands of research is far from complete, this article carries the
effort forward by reviewing contributions from the 1970s to the present in three
major lines of research: citation classification, content analysis of citation
contexts, and studies of citer motivations. I pay particular attention to ideas
that bear on teaching the art of citing--for example, in courses in English for
research purposes--and to controversies in citation research of interest to
discourse analysts.

Resumen: The Internet is a convenient but complex source for health
information used by an increasing number of health consumers. Especially for
people suffering from a chronic illness (e.g., diabetes), information seeking
forms a part of the daily management of the disease, a 'project of life.' This
study of Web texts examines the citation patterns for a specific and
controversial health issue: the beneficial or hazardous use of dietary chromium
supplementation in diabetes self-management. Texts from different categories of
Web sources (scientific, professional, educational, and commercial sources, as
well as diabetes discussion groups) were analyzed in order to study how
knowledge is transferred between sources, and how diabetics participating in
discussion groups refer to and make sense of the information from different
sources on the Internet. The citation patterns suggest that deviations from the
traditional models of scientific knowledge dissemination can occur in the
Internet environment.

evaluate the range of research methodologies used and the level of collaboration
among academic librarians, LIS faculty members, and others. The research results
extend the prior self-report research in this area and indicate that academic
librarians, administrators, and LIS faculty are authors of most of the published
research in highly ranked journals. The level of collaboration among those in
different types of roles is limited, however. In addition, most of the research
articles have been authored or coauthored by those in research university

Resumen: Author co-citation analysis (ACA) has been widely used in
bibliometrics as an analytical method in analyzing the intellectual structure of
science studies. It can be used to identify authors from the same or similar
research fields. However, such analysis method relies heavily on statistical
tools to perform the analysis and requires human interpretation. Web Citation
Database is a data warehouse used for storing citation indices of Web
publications. In this paper, we propose a mining process to automate the ACA
based on the Web Citation Database. The mining process uses agglomerative
hierarchical clustering (AHC) as the mining technique for author clustering and
multidimensional scaling (MDS) for displaying author cluster maps. The
clustering results and author cluster map have been incorporated into a
citation-based retrieval system known as PubSearch to support author retrieval
of Web publications.

Resumen: Author Cocitation Analysis (ACA) and Web Colink Analysis (WCA)
are examined as sister techniques in the related fields of bibliometrics and
webometrics. Comparisons are made between the two techniques based on their data
retrieval, mapping, and interpretation procedures, using mathematics as the
subject in focus. An ACA is carried out and interpreted for a group of
participants (authors) involved in an Isaac Newton Institute (2000)
workshop-Singularity Theory and Its Applications to Wave Propagation Theory and
Dynamical Systems-and compared/contrasted with a WCA for a list of international
mathematics research institute home pages on the Web. Although the practice of
ACA may be used to inform a WCA, the two techniques do not share many elements
in common. The most important departure between ACA and WCA exists at the
interpretive stage when ACA maps become meaningful in light of citation theory,
and WCA maps require interpretation based on hyperlink theory. Much of the
research concerning link theory and motivations for linking is still new;
therefore further studies based on colinking are needed, mainly map-based
studies, to understand what makes a Web colink structure
meaningful.
