Centre for Science and Technology Studies

The Centre for Science and Technology Studies (CWTS) studies scientific research and its connections to technology, innovation, and society. Our research, bibliometric and scientometric tools, and evaluation expertise provide a solid basis for supporting research assessment and strategic decision making and for developing science policy.





  • Visualizing freely available citation data using VOSviewer

    Today we released version 1.6.6 of our VOSviewer software for constructing and visualizing bibliometric networks. The most important new feature in this version is the support for working with Crossref data. Recently, the Initiative for Open Citations (I4OC) managed to convince a large number of scientific publishers to make the reference lists of publications in their journals freely available through Crossref. Thanks to I4OC, Crossref has become a valuable data source for VOSviewer users. In this blog post, we discuss how users of the new version 1.6.6 of VOSviewer can benefit from Crossref data.

  • To distinguish between an elephant and a rabbit: Citizen bibliometrics in biomedicine and economics

    In recent years there has been an increasing interest in how evaluation systems and resource allocation models affect research. A central question is how an increased focus on performance that is quantifiable affects researchers' practices and priorities. A number of documented and possible effects have been identified on a more general level (de Rijcke et al., 2016), but empirical studies of how bibliometric is used in evaluating individuals are few. Assessment at the individual level is difficult to study empirically. As a result, previous discussions were based primarily on individual examples and anecdotes. At the same time, this use of indicators is particularly important for individual careers as employment and research funding are at stake.
