We describe herein the IBM Statistical Question Answering system for TREC-10 in detail. Basedon experiences in TREC-9, we have adapted our system to deal with definition type questions andfurthermore completed the trainability aspect of our question-answering system. The experimentsperformed in this evaluation confirmed our hypothesis that post-processing the IR engine resultscan achieve the same performance as incorporating query expansion terms into the retrieval engine. |
