THUIR at TREC 2007: Enterprise Track

We participate in document search and expert search of Enterprise Track in TREC2007. The motive behind the TREC Enterprise Track is to study the issues searching the documents and experts inside an enterprise environment, which has not been sufficiently addressed in research. In document search, we focus on the key overview page pre-selection methods and link analysis algorithms. In expert search, we develop methods to detect expert identifiers and experimented based on our previous PDD model.
