| Abstract: | Resent years, the Automatic Question Answering technique has become a popular research field in Natural Language Processing. The knowledge base of the traditional Question Answering system is generally based on the set of fixed texts, while the abundant information in the Web provides the QA system with another kind of resources. This paper develops a Web-based Restricted Chinese QA system, Testing with a small set of queries on weather domain, and improving high precision of the system. |
