QUESTION ANSWERING USING QUESTION CLASSIFICATION AND DOCUMENT TAGGING

Question answering (QA) is a relatively new area of research. We took the approach of designing a question answering system that is based on question classification and document tagging. Question classification extracts useful information from the question about how to answer the question. Document tagging extracts useful information from the documents, which are used to find the answer to the question. We used different available systems to tag the documents. Our system classifies the questions using manually developed rules. An evaluation of the system is performed using Text REtrieval Conference (TREC) data.
