Term Weighting in Expert Search Task: Analyzing Communication Patterns?
The goal of the expert search task is nding knowledgeable persons within the enterprise. In this paper we focus on its distinctions from the other information retrieval tasks. We review the existing approaches and propose a new term weighting scheme which is based on analysis of communication patterns between people. The eectiveness of the proposed approach is evaluated on a collection of e-mails from an organization of approximately 1500 people. Results show that it is possible to take into account communication structure in the process of term weighting, eectively combining communication-based and document-based approaches to expert finding.
