Automated Answering System for a product using opinion mining

Though computers are considered as machines, they are expected to give answers to questions in normal English language, just the way human beings can do. To train a computer to answer English language questions is an interesting and challenging problem. These problems are handled under two categories: open Domain problems and close domain problems. In this paper a question answering scheme is proposed for close domain systems. The question answering system for closed domain deals with questions under specific domain. Answers to questions from close domain cannot be searched using a search engine. During a close domain, answers to questions are not alive in the public area and so they cannot be search using a search engine. Hence, the answers to such questions are maintained in a database by the domain expert. During retrieval of answers, the best matched answer searched from database is returned to the user. To perform this matching a template matching technique is used. Thus the main challenge of the proposed scheme is to understand the English language question to get the correct answer from the database.
