UvA-DARE ( Digital Academic Repository ) Using Wikipedia at the TREC QA Track

We describe our participation in the TREC 2004 Question Answering track. We provide a detailed account of the ideas underlying our approach to the QA task, especially to the so-called “other” questions. This year we made essential use of Wikipedia, the free online encyclopedia, both as a source of answers to factoid questions and as an importance model to help us identify material to be returned in response to “other” questions.
