We assessed all papers published in two key environmental modelling journals in 2008 to determine the degree to which the citation counts of the papers could be predicted without considering the paper’s quality. We applied both random forests and general additive models to predict citation counts using a range of easily quantified or categorised characteristics of the papers as covariates. The ...

Visualization can facilitate the understanding of the structures of a collection of documents that are related to each other by links, such as citations in formal publications. We present results of visualizing minimum spanning trees based on document co-citation counts and on document citation correlations.

Data from samples of biochemists and sociologists show that nearly all are familiar with citation indexes and that the two groups are equally likely to have used a citation index for bibliographic purposes. We develop three hypotheses from social comparison theory to account for variation in use and evaluation of citation counts as indicators of scientific achievement: (1) more highly cited sci...

Using publication and citation data from a study on the selection procedure of the Boehringer Ingelheim Fonds (B.I.F.), this study investigated the extent to which frequently and infrequently cited articles were used differently by the scientists that cited them. The data set consisted of 31 articles by B.I.F. grant applicants that had received 451 citations in 270 citing publications. In a com...

Microsoft Academic is a free citation index that allows large scale data collection. This combination makes it useful for scientometric research. Previous studies have found that its citation counts tend to be slightly larger than those of Scopus but smaller than Google Scholar, with disciplinary variations. This study reports the largest and most systematic analysis so far, of 172,752 articles...

Citations published in online supplementary material (OSM) are invisible to search engines used to calculate citation counts, potentially negatively impacting popular performance indices and journal rankings that rely on citation counts for quantification. To quantify the number of citations that are "lost" in OSM, we conducted a systematic survey of supplementary citation practices in four hig...

Counts of citations to academic articles are widely used as indicators of their scholarly impact. In addition, alternative indicators derived from social websites have been proposed to cover some of the shortcomings of citation counts. The most promising such indicator is counts of readers of an article in the social reference sharing site Mendeley. Although Mendeley reader counts tend to corre...
