Liyun Ru, Le Zhao, Min Zhang, Shaoping Ma · Text REtrieval Conference · 2004
This is the third years that Tsinghua University Information Retrieval Group (THUIR) participates in Novelty task of TREC. Our research on this year’s novelty track mainly focused on four aspects: (1) text feature selection and reduction; (2) improved sentence classification in finding relevant information; (3)efficient sentence redundancy computing; (4) effective result filtering. All experiments have been performed on TMiner IR system, developed by THU IR group last year.
