Abstract:We introduce a novel approach to expert nding based on
multi-step relevance propagation from documents to related
candidates. Relevance propagation is modeled with an ab-
sorbing random walk. The evaluation on the two ocial
Enterprise TREC data sets demonstrates the advantage of
our method over the state-of-the-art method based on one-
step propagation.
