Usage Bibliometrics
Scholarly usage data provides unique opportunities to address the known
shortcomings of citation analysis. However, the collection, processing and
analysis of usage data remains an area of active research. This article
provides a review of the state-of-the-art in usage-based informetric, i.e. the
use of usage data to study the scholarly process.Comment: Publisher's PDF (by permission). Publisher web site:

Comparing People with Bibliometrics
Bibliometric indicators, citation counts and/or download counts are
increasingly being used to inform personnel decisions such as hiring or
promotions. These statistics are very often misused. Here we provide a guide to
the factors which should be considered when using these so-called quantitative
measures to evaluate people. Rules of thumb are given for when begin to use
bibliometric measures when comparing otherwise similar candidates.Comment: to appear in Proceedings of Library and Information Science in

Social reference: Aggregating online usage of scientific literature in CiteULike for clustering academic resources
Citation-based methods have been widely studied and employed for clustering academic resources and mapping science. Although effective, these methods suffer from citation delay. In this study, we extend reference and citation analysis to a broader notion from social perspective. We coin the term "social reference" to refer to the references of literatures in social academic web environment. We propose clustering methods using social reference information from CiteULike. We experiment for journal clustering and author clustering using social reference and compare with citation-based methods. Our experiments indicate: first, social reference implies connections among literatures which are as effective as citation in clustering academic resources; second, in practical settings, social reference-based clustering methods are not as effective as citation-based ones due to the sparseness of social reference data, but they can outperform in clustering new resources that have few citation. © 2011 Authors
How the Scientific Community Reacts to Newly Submitted Preprints: Article Downloads, Twitter Mentions, and Citations
We analyze the online response to the preprint publication of a cohort of
4,606 scientific articles submitted to the preprint database arXiv.org between
October 2010 and May 2011. We study three forms of responses to these
preprints: downloads on the arXiv.org site, mentions on the social media site
Twitter, and early citations in the scholarly record. We perform two analyses.
First, we analyze the delay and time span of article downloads and Twitter
mentions following submission, to understand the temporal configuration of
these reactions and whether one precedes or follows the other. Second, we run
regression and correlation tests to investigate the relationship between
Twitter mentions, arXiv downloads and article citations. We find that Twitter
mentions and arXiv downloads of scholarly articles follow two distinct temporal
patterns of activity, with Twitter mentions having shorter delays and narrower
time spans than arXiv downloads. We also find that the volume of Twitter
mentions is statistically correlated with arXiv downloads and early citations
just months after the publication of a preprint, with a possible bias that
favors highly mentioned articles.Comment: 15 pages, 7 Figures, 3 Tables. PLoS One, in pres
