SSRN-Whose Metrics? On Building Citation, Usage and Access Metrics as Information Service for Scholars by Chris Armbruster

As the Internet has enhanced the collection and provision of citation, usage and access metrics, the challenge lies neither in the technology nor the method, but in constructing databases that deliver services of value to the scholar. However, the development of metrics has hitherto been driven by the needs of external research assessment (governments and funders), while publishers and libraries have focused on their own needs (e.g. journal impact and usage factors). Scholars often criticize research assessment and the use of particular metrics as a zero-sum game whose undesirable consequences far outweigh the benefits. However, this is not to be confused with a general prejudice against metrics, which are principally compatible with the scholarly recognition and rewards system. But it does indicate that current metric information services often do not serve the needs of scholars. The question everybody should be asking is: What kind of metric information services would serve scholars? The argument proceeds in six steps. First, the problematic and controversial nature of assessment metrics is discussed. Second, the limited value of current metric information services is outlined. Third, the notion of metrics as research information services is clarified. Fourth, some examples of such services are offered. Fifth, the potential value is sketched from the perspective of a postdoc. Sixth, it is indicated that societies and publishers could begin building more metric information services since tried-and-tested technology and methods are available already.

Bibliometrics and Citation Analysis (Scarecrow Press, Inc.)

Can the methods of science be directed toward science itself? How did it happen that scientists, scientific documents, and their bibliographic links came to be regarded as mathematical variables in abstract models of scientific communication? What is the role of quantitative analyses of scientific and technical documentation in current science policy and management? Bibliometrics and Citation Analysis: From the Science Citation Index to Cybermetrics answers these questions through a comprehensive overview of theories, techniques, concepts, and applications in the interdisciplinary and steadily growing field of bibliometrics.

Usage-based measurements of journal quality - research project enters its second stage | UKSG

In 2007 the United Kingdom Serials Group (UKSG), in association with the online usage metrics organisation COUNTER, published the results of a wide-ranging study which explored how online journal usage statistics might form the basis of a new metric of journal quality. The study combined a web-based survey of opinion with a series of in-depth interviews with stakeholders from the author, publisher and librarian communities. The aim of these twin avenues of research was to examine the ways in which journal quality is currently assessed, and the degree to which any additional usage-based metrics might prove valuable to each stakeholder community, along with practical ways in which such metrics might be derived and constructed to provide the maximum utility for all, within defined resource constraints. Building upon the encouraging reactions revealed in the market research, Stage 2 of the project is developing a programme of data modelling and analysis that will use real usage data from a number of content providers, with the aim of identifying potential candidate metrics for longer term scaled up testing.

Why the impact factor of journals should not be used for evaluating research -- Seglen 314 (7079): 497 -- BMJ

Evaluating scientific quality is a notoriously difficult problem which has no standard solution. Ideally, published scientific results should be scrutinised by true experts in the field and given scores for quality and quantity according to established rules. In practice, however, what is called peer review is usually performed by committees with general competence rather than with the specialist's insight that is needed to assess primary research data. Committees tend, therefore, to resort to secondary criteria like crude publication counts, journal prestige, the reputation of authors and institutions, and estimated importance and relevance of the research field,1 making peer review as much of a lottery as of a rational process.2 3

[0902.2183] A principal component analysis of 39 scientific impact measures

The impact of scientific publications has traditionally been expressed in terms of citation counts. However, scientific activity has moved online over the past decade. To better capture scientific impact in the digital era, a variety of new impact measures has been proposed on the basis of social network analysis and usage log data. Here we investigate how these new measures relate to each other, and how accurately and completely they express scientific impact. We performed a principal component analysis of the rankings produced by 39 existing and proposed measures of scholarly impact that were calculated on the basis of both citation and usage log data. Our results indicate that the notion of scientific impact is a multi-dimensional construct that can not be adequately measured by any single indicator, although some measures are more suitable than others. The commonly used citation Impact Factor is not positioned at the core of this construct, but at its periphery, and should thus be used with caution.

The integration of open access journals in the scholarly communication system: Three science fields

Abstract: The greatest number of open access journals (OAJs) is found in the sciences and their influence is growing. However, there are only a few studies on the acceptance and thereby integration of these OAJs in the scholarly communication system. Even fewer studies provide insight into the differences across disciplines. This study is an analysis of the citing behaviour in journals within three science fields: biology, mathematics, and pharmacy and pharmacology. It is a statistical analysis of OAJs as well as non-OAJs including both the citing and cited side of the journal to journal citations. The multivariate linear regression reveals many similarities in citing behaviour across fields and media. But it also points to great differences in the integration of OAJs. The integration of OAJs in the scholarly communication system varies considerably across fields. The implications for bibliometric research are discussed.

Literature Citations in the Internet Era -- Gingras et al. 323 (5910): 36a -- Science

J. A. Evans's Report "Electronic publication and the narrowing of science and scholarship" (18 July, p. 395) suggests that (i) the average age of citations to scientific papers dropped over the years as more electronic papers became accessible and (ii) the citations are concentrated on a smaller proportion of papers and journals. Such conclusions are not warranted by Evans's data. To measure the evolution of the average (or median) age of the references contained in papers, one has to look at all the references in all published papers and observe the evolution of their age over time. As we have shown using Thomson Reuters's Web of Science data for the period 1900 to 2004 (for a total of 500 million references in 25 million papers), the average (and median) age of all references began to decrease in 1945 but has increased steadily since the mid-1960s. This trend is visible in all sciences, including the social sciences and the humanities (1, 2). The median age of references in fields of science and engineering moved from 4.5 years in 1955 to more than 7 years in 2004, and in medical sciences it increased from 4.5 to 5.5 during the same period (1). In fact, Evans's conclusions only reflect a transient phenomenon related to recent access to online publications and to the fact that the method used does not take into account time delays between citation year and publication year. Our data also show that in disciplines in which online access has been available the longest (such as nuclear physics and astrophysics), the age of references declines for a number of years in the 1990s but then increases from 2000 to 2007, the last available year of our data set. We have also measured the concentration of citations (and journals) by three different methods, including the one used by Evans. All three measures clearly show that concentration is in fact declining for papers as well as for journals (3). Although many factors affect citation practices, two things are clear: Researchers are increasingly relying on older science, and citations are increasingly dispersed across a larger proportion of papers and journals.

Is physics better than biology? : Nature News

Claudio Castellano at the Sapienza University of Rome and his colleagues have found that the statistics of citations follow a virtually identical pattern in disciplines as varied as nuclear physics, haematology and agricultural economics. As a result, indices of scientific performance based on citations can be normalized to account for differences in the overall citation rates of different disciplines, allowing for more meaningful comparisons. This doesn't just apply to departments. Castellano says it can be used to grade scientists, whole countries or just about any group you like.

The Coming of Age of E-Prints in the Literature of Physics

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.

Inter Research » Journals » ESEP » Theme Sections

Quantifying the relative performance of individual scholars, groups of scholars, departments, institutions, provinces/states/regions and countries has become an integral part of decision-making over research policy, funding allocations, awarding of grants, faculty hirings, and claims for promotion and tenure. Bibliometric indices (based mainly upon citation counts), such as the h-index and the journal impact factor, are heavily relied upon in such assessments. There is a growing consensus, and a deep concern, that these indices — more-and-more often used as a replacement for the informed judgement of peers — are misunderstood and are, therefore, often misinterpreted and misused. The articles in this ESEP Theme Section present a range of perspectives on these issues. Alternative approaches, tools and metrics that will hopefully lead to a more balanced role for these instruments are presented. Contents Theme Section articles appear online (as final unpaginated proofs) as soon as they are finalized by the authors. They will be paginated when the Theme Section is complete.

Peter Suber, Open Access News

Matthew E. Falagas and three co-authors, Comparison of SCImago journal rank indicator with journal impact factor, FASEB Journal, April 11, 2008. Only this abstract is free online, at least so far: The application of currently available sophisticated algorithms of citation analysis allows for the incorporation of the "quality" of citations in the evaluation of scientific journals. We sought to compare the newly introduced SCImago journal rank (SJR) indicator with the journal impact factor (IF). We retrieved relevant information from the official Web sites hosting the above indices and their source databases. The SJR indicator is an open-access resource, while the journal IF requires paid subscription. The SJR indicator (based on Scopus data) lists considerably more journal titles published in a wider variety of countries and languages, than the journal IF (based on Web of Science data). Both indices divide citations to a journal by articles of the journal, during a specific time period. However, contrary to the journal IF, the SJR indicator attributes different weight to citations depending on the "prestige" of the citing journal without the influence of journal self-citations; prestige is estimated with the application of the PageRank algorithm in the network of journals. In addition, the SJR indicator includes the total number of documents of a journal in the denominator of the relevant calculation, whereas the journal IF includes only "citable" articles (mainly original articles and reviews). A 3-yr period is analyzed in both indices but with the use of different approaches. Regarding the top 100 journals in the 2006 journal IF ranking order, the median absolute change in their ranking position with the use of the SJR indicator is 32 (1st quartile: 12; 3rd quartile: 75). Although further validation is warranted, the novel SJR indicator poses as a serious alternative to the well-established journal IF, mainly due to its open-access nature, larger source database, and assessment of the quality of citations.

SSRN-Access, Usage and Citation Metrics: What Function for Digital Libraries and Repositories in Research Evaluation? by Chris Armbruster

Abstract: The growth and increasing complexity of global science poses a grand challenge to scientists: How to organise the worldwide evaluation of research programmes and peers? For the 21st century we need not just information on science, but also meta-level scientific information that is delivered to the digital workbench of every researcher. Access, usage and citation metrics will be one major information service that researchers will need on an everyday basis to handle the complexity of science. Scientometrics has been built on centralised commercial databases of high functionality but restricted scope, mainly providing information that may be used for research assessment. Enter digital libraries and repositories: Can they collect reliable metadata at source, ensure universal metric coverage and defray costs? This systematic appraisal of the future role of digital libraries and repositories for metric research evaluation proceeds by investigating the practical inadequacies of current metric evaluation before defining the scope for libraries and repositories as new players. Subsequently the notion of metrics as research information services is developed. Finally, the future relationship between a) libraries and repositories and b) metrics databases, commercial or non-commercial, is addressed. Service reviewed include: Leiden Ranking, Webometrics Ranking of World Universities, COUNTER, MESUR, Harzing POP, CiteSeer, Citebase, RePEc LogEc and CitEc, Scopus, Web of Science and Google Scholar.

Show me the data -- Rossner et al. 179 (6): 1091 -- The Journal of Cell Biology

The integrity of data, and transparency about their acquisition, are vital to science. The impact factor data that are gathered and sold by Thomson Scientific (formerly the Institute of Scientific Information, or ISI) have a strong influence on the scientific community, affecting decisions on where to publish, whom to promote or hire (1), the success of grant applications (2), and even salary bonuses (3). Yet, members of the community seem to have little understanding of how impact factors are determined, and, to our knowledge, no one has independently audited the underlying data to validate their reliability.

[cs/0703131] Open Access Scientometrics and the UK Research Assessment Exercise

Scientometric predictors of research performance need to be validated by showing that they have a high correlation with the external criterion they are trying to predict. The UK Research Assessment Exercise (RAE), together with the growing movement toward making the full-texts of research articles freely available on the web -- offer a unique opportunity to test and validate a wealth of old and new scientometric predictors, through multiple regression analysis: Publications, journal impact factors, citations, co-citations, citation chronometrics (age, growth, latency to peak, decay rate), hub/authority scores, h-index, prior funding, student counts, co-authorship scores, endogamy/exogamy, textual proximity, download/co-downloads and their chronometrics, etc. can all be tested and validated jointly, discipline by discipline, against their RAE panel rankings in the forthcoming parallel panel-based and metric RAE in 2008. The weights of each predictor can be calibrated to maximize the joint correlation with the rankings. Open Access Scientometrics will provide powerful new means of navigating, evaluating, predicting and analyzing the growing Open Access database, as well as powerful incentives for making it grow faster.

Peer-to-Peer: Tracking quality of peer review

"Satisfactory reviews were compared to unsatisfactory ones, and excellent reviews were separately compared to average. For both of these cases, correlations were tested with a number of factors thought to improve reviewing skills (participation in grant reviews, years of experience, prior coursework in critical appraisal, etc.). These factors were tested both individually and in a multivariable analysis, which should eliminate any confounding factors. In news that may be disturbing for journal editors everywhere, very few factors leapt out as having a consistent and significant correlation with the quality of a review, although some factors did have strong correlations in individual tests. The only positive factors linked to quality of reviews were age (younger reviewers were better) and working at an academic hospital. Ironically, service on an Institutional Review Board, which evaluates and approves experiments on humans, consistently correlated with lower-quality peer reviews. Even these factors, however, were only slightly better than random at predicting review quality." Dr Timmer concludes: "There are some clear limitations to this study, given that it applies to a single journal with content that's exclusively medical. But the researchers who performed it note that it may be difficult to extend these studies to other fields, as many journals don't even have a mechanism for evaluating or tracking the quality of reviewers. Given the importance of peer review to the entire scientific enterprise, their strongest conclusion is that more needs to be done to track and evaluate the process in order to ensure that the body of published information is as reliable as possible."

About Authoratory

The content of Authoratory is produced by analyzing large amounts of data from PubMed. PubMed is a service of the U.S. National Library of Medicine that includes over 16 million citations from MEDLINE and other life science journals for biomedical articles back to the 1950s. PubMed includes links to full text articles and other related resources. Authoratory data-mining techniques make it possible to discover new information about the authors - the information that is not apparent by reviewing one or two of their articles. For each selected author Authoratory gives the following: * the author status: primary or non-primary (primary author publishes articles independently, while non-primary always publishes articles with another author or a group of authors) * the list of most frequent coauthors (navigate the social network between the authors using their join publications) * professional interests (as indicated by the MeSH keywords and by the statistical analysis of abstracts and publication titles) * the author's affiliated institution and contact information * the change of all these parameters across time Authoratory keyword search is unique as well. It uses keyword frequencies to rank authors against each other. The more papers the particular author publishes for a specific keyword, the higher his rank is in the keyword listings. With Authoratory keyword search it 's possible to quickly find all authors with the expertise in a specific narrow topic.

Unilever Centre for Molecular Informatics, Cambridge - petermr’s blog » Blog Archive » Could an Open chemistry journal fly?

Chemistry exemplifies the artificial citation economy which is destructive of innovation and amplifies statis. Effectively chemists (like me) are judged on their formal publication record in journals with high impact factors. Maybe this is the best we can do, but it means that anything that isn’t a formal publication in an established leading journal is very difficult to justify. It doesn’t get promotion, it doesn’t get funding, it doesn’t get the institution credit. And the process is increasingly mechanised. I have heard chemists who say that in the US (and probably elsewhere) promotion is determined solely by the number of publications (or possibly citations) in the Journal Of The American Chemical Society. And how are these citations measured? We leave it to a commercial company (such as Thomson ISI) to give us metrics about academic value. In other words we have no metric or worth of our own - we rely on a process which is driven by how much money an independent company can make out of it.

OAN: Publication metrics, including the OA impact advantage

Simpy can't deal with anchor tags, it seems. http://www.earlham.edu/~peters/fos/2006_10_29_fosblogarchive.html#116252848123170668 Colin Steele, Linda Butler, and Danny Kingsley, The publishing imperative: the pervasive influence of publication metrics, Learned Publishing, October 2006 (accessible only to subscribers). See the self-archived, OA copy.

Abstract: This article summarises the effects of the increasing global trend towards measuring research quality and effectiveness through, in particular, publication-based metrics, and its effects on scholarly communication. Such metrics are increasingly influencing the behaviour patterns of administrators, publishers, librarians and researchers. Impact and citation measures, which often rely solely on Thomson Scientific data, are examined in the context of university league tables and research assessment exercises. The need to establish alternate metrics, particularly for the social sciences and humanities, is emphasised, as is an holistic approach to scholarly communication agendas.
