Recently, there has been an increased interest in the use of social media data as important traffic information sources and as a data research in the field of Human and Social Sciences. Social media are used, for example, to identify Twitter user communities in the context of altmetrics. In this paper, we highlight the potential use of social media data analysis by non computer science research...

Despite contradicting evidence that open access (OA) articles might have greater citation advantage, there is less case studies in developing countries showing whether their global publication availability pattern advantages scientific impact metrics. Also, by addition of altmetrics to the world scientific evaluation system it is less known how different research access channels such as OA publ...

Abstract This study investigates the effect of competitive project funding on researchers’ publication outputs. Using detailed information applicants at Swiss National Science Foundation and their proposal evaluations, we employ a case-control design that accounts for individual heterogeneity researchers selection into treatment (e.g. funding). We estimate impact grant award set output indicato...

What paper should I read next? Who should I talk to at a conference? Which research group should get this grant? Researchers and funders alike must make daily judgments on how to best spend their limited time and money–judgments that are becoming increasingly difficult as the volume of scholarly communication increases. Not only does the number of scholarly papers continue to grow, it is joined...

Medical research is highly funded and often expensive and so is particularly important to evaluate effectively. Nevertheless, citation counts may accrue too slowly for use in some formal and informal evaluations. It is therefore important to investigate whether alternative metrics could be used as substitutes. This article assesses whether one such altmetric, Mendeley readership counts, correla...

Bibliometrics is successful in measuring impact, because the target is clearly defined: the publishing scientist who is still active and working. Thus, citations are a target-oriented metric which measures impact on science. In contrast, societal impact measurements based on altmetrics are as a rule intended to measure impact in a broad sense on all areas of society (e.g. science, culture, poli...
