Expertise overlap between an expert panel and research groups in global journal maps

There are no available methods to measure overlap in expertise between a panel of experts and evaluated research groups in discipline-specific research evaluation. This paper explores a bibliometric approach to determining the overlap of expertise, using the 2009 and 2011 research evaluations of ten Pharmaceutical Sciences and nine Biology research groups of the University of Antwerp. We study this overlap at the journal level. Specifically, journal overlay maps are applied to visualize to what extent the research groups and panel members publish in the same journals. Pharmaceutical Sciences panel members published more diversely than the corresponding research groups, whereas, the Biology research groups published more diversely than the panel. Numbers of publications in the same journals vary over a large scale. A different range of coverage was found for different research groups; there is also a significant difference between maximum and minimum coverage based on discipline. Future research will focus on similarity testing, and a comparison with other disciplines
