Searching the Web for Alternative Answers to Questions on WebQA Sites

摘要：

We propose a method of discovering alternative answers from the Web that are to a question posted on a Web question & answer (Q&A) site and differ from existing answers to the question on the Q&A site. Our method first automatically generates queries for conventional Web search engines to collect Web pages that can contain answers to the target question. Each collected Web page is evaluated by calculating two kinds of scores: one represents the probability that the page has information that answers a question in the Q&A content anti the other represents the possibility that it has an alternativc answer. The method is implemented and the system is evaluatcd using actual Q&A contents.
