THUIR at TREC 2008: Enterprise Track

We participate in document search and expert search of Enterprise Track in TREC2008. The corpus and tasks are same as the year before. Different from TREC 2007, the topics come from CSIRO Enquiries, and the topic statements are richer and more colloquial.. In document search, we look into the key resource page pre-selection, the use of anchor text, query classification, and multi-field search. In expert search, we develop methods to detect expert identifiers and experimented based on our previous PDD (personal description documents) model.
