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.

How citation distortions create unfounded authority: analysis of a citation network -- Greenberg 339: b2680 -- BMJ

Objective To understand belief in a specific scientific claim by studying the pattern of citations among papers stating it. Design A complete citation network was constructed from all PubMed indexed English literature papers addressing the belief that β amyloid, a protein accumulated in the brain in Alzheimer’s disease, is produced by and injures skeletal muscle of patients with inclusion body myositis. Social network theory and graph theory were used to analyse this network. Main outcome measures Citation bias, amplification, and invention, and their effects on determining authority. Results The network contained 242 papers and 675 citations addressing the belief, with 220 553 citation paths supporting it. Unfounded authority was established by citation bias against papers that refuted or weakened the belief; amplification, the marked expansion of the belief system by papers presenting no data addressing it; and forms of invention such as the conversion of hypothesis into fact through citation alone. Extension of this network into text within grants funded by the National Institutes of Health and obtained through the Freedom of Information Act showed the same phenomena present and sometimes used to justify requests for funding. Conclusion Citation is both an impartial scholarly method and a powerful form of social communication. Through distortions in its social use that include bias, amplification, and invention, citation can be used to generate information cascades resulting in unfounded authority of claims. Construction and analysis of a claim specific citation network may clarify the nature of a published belief system and expose distorted methods of social citation.

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.

eFoundations: Influence, connections and outputs

if we really want to develop "some sensible measure of scholarly impact on the social Web" then we have to step back and consider three questions:\n\n * what do we want to measure?\n * what can we measure?\n * how can bring these two things close enough together to create something useful?\nThese two are clearly related, at least in the sense that someone's level of engagement in a community (their connectedness if you like) clearly increases the exposure of their work but is also indicative of the credibility they have within that community. Having said that, my gut feeling is that credibility, at least for the purposes of scholarly communication, can only really be measured by some kind of a peer-review (i.e. human) process.

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.

philosophi.ca : MLA Digital Work

E.g.: "Blogs are an emergent form for the academy. They are particularly hard to evaluate since they don’t resemble any traditional academic form. A good blogger (or team of bloggers) however, do a great service to the community by tracking a field and commenting on it. The better blogs will include short reviews, announcements, interesting interventions and notes about timely matters like exhibits. Blogs, as I have learned, take habits of attention. Each post might take half an hour to an hour to research and post. They may appear to be light and quick, but the good bloggers acquire a voice and engage an audience. In some ways running a blog is like moderating a discussion list. How often does Willard McCarty post a provocative note to HUMANIST to promote discussion? The work of facilitating the conversations we value in the humanities should not be dismissed as service. It is possible the most lasting academic work of this age will be the social networking that allows others a voice. This is comparable to the work of translation or editorial work where transparency leads to illegitimacy – if you do such a good job that no one notices you then no one things you are doing good work."

OAN: Using citation data to shed light on access restrictions

Patrick Gaulé, Access to the scientific literature in India, CEMI Working Paper 2009-004, February 23, 2009. Abstract: This paper uses an evidence-based approach to assess the difficulties faced by developing country scientists in accessing the scientific literature. I compare backward citations patterns of Swiss and Indian scientists in a database of 43'150 scientific papers published by scientists from either country in 2007. Controlling for fields and quality with citing journal fixed effects, I find that Indian scientists (1) have shorter references lists (2) are more likely to cite articles from open access journals and (3) are less likely to cite articles from expensive journals. The magnitude of the effects is small which can be explained by informal file sharing practices among scientists.

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.
