Using Citation Analysis for Finding Experts in Workgroups

We compare expert finding approaches that use and combine different types of expertise evidence: content-based expert finding using academic papers, and expert finding using a social citation network between the documents and authors. We evaluate our approaches on a test collection that represents the research output of a typical average-sized academic workgroup. We find that expert finding using static rankings achieves the same performance as a query-dependent approach. Of the different approaches, the most effective method of performing expert finding in an academic workgroup is ranking workgroup members by citation indegree.
