DUTIR at TREC 2007 Genomics Track

This paper describes our experiments on TREC 2007 Genomics Track which is concerned with question answering extraction from full-text biomedical literatures. In our experiment, named entities were recognized at the preprocessing stage using a two-view method. MeSH was used to expand the terms. We performed passage retrieval by using sentence-level half overlapped sliding windows. Indri structured query language operators were also used to construct queries.
