Abstract

The present paper explores simultaneous modeling of cross-reference activity between authors by use of asymmetric proximities and multidimensional unfolding. We thereby model and map both citing and cited relations between authors in a common space. This enables a more comprehensive comparison of the authorís dual roles of citing and being cited in a reference network. We model a set of 31 authors and compare the results to a recent author co-citation study of information science. We find that multidimensional unfolding is a reliable and insightful technique for modeling authorís citing and cited dimensions simultaneously. The common space of citing and cited positions do exemplify that some authors have substantial discrepancies between their citing behaviour and the way their works are used by peers in the set. Further, modelling mutual relationships as asymmetric brings more precision, accuracy and nuances into the maps as relationships become overt. Finally, the study finds that publication activity can influence mapping results considerably. We demonstrate the appropriateness of correcting data for main effects by use of an an asymmetric proximity measure of odds ratios.
