A textual measure of the interdisciplinarity of scientific papers — •Laercio Dias, Martin Gerlach, and Eduardo G. Altmann — Max Planck Institute for the Physics of Complex Systems, D-01187 Dresden, Germany

We are interested in investigating the role and impact of interdisciplinary publications in the evolution of scientific ideas. A crucial point is how to quantify interdisciplinarity. The traditional approach is to use citation networks. The goal of our work is to construct a measure of interdisciplinarity entirely based on the text of articles, taking advantage of the increasing availability of full text of publications. We propose and compare different methods based on Jensen-Shannon-type of divergences, following the ideas recently proposed in Ref. [1].
