This paper contributes to the quest for an operational definition of 'research excellence' and proposes a translation of the excellence concept into a bibliometric indicator. Starting from a textual analysis of funding program calls aimed at individual researchers and from the challenges for an indicator at this level in particular, a new type of indicator is proposed. The Impact Vitality indicator [RONS & AMEZ, 2008] reflects the vitality of the impact of a researcher's publication output, based on the change in volume over time of the citing publications. The introduced metric is shown to posses attractive operational characteristics and meets a number of criteria which are desirable when comparing individual researchers. The validity of one of the possible indicator variants is tested using a small dataset of applicants for a senior full time Research Fellowship. Options for further research involve testing various indicator variants on larger samples linked to different kinds of evaluations.
The application of micro-level citation indicators is not without controversy. The procedure requires the availability of both adequate data sets and trusted metrics. Few indicators have been developed to deal specifically with individual assessment. The h-type indices are the most popular category; however, the dependence of h-type metrics on publication age and field makes their application often unjustified. This article studies the effects that publication age and field normalization have on h-type citation values of German Leibniz Prize winners. This data set is exclusive in that it is highly scrutinized for homonyms. Results are compared with other field-normalized citation rates, contributing to the debate on using demarcation versus average citation approaches to evaluate top researchers.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
