Abstract
Expert search has been studied in different contexts, e.g. enterprises, academic
communities. We examine a general expert search problem: searching experts on the Web,
where millions of Web pages and thousands of names are considered. It has mainly two
challenging issues: (1) Web pages could be of varying quality and full of noises; (2) The
expertise evidences scattered in Web pages are usually vague and ambiguous. We propose
to leverage the large amount of co-occurrence information to assess the relevance and
reputation of a person name for a query. The co-occurrence structure is modeled by a
hypergraph, on which a heat diffusion based ranking algorithm is proposed.
