Study of Intelligent Question Answering System Based on Ontology

摘要

This paper designs Intelligent Question Answering System (IQAS) by a combined use of the concept of ontology and search engine. The system can help users to obtain more accurate answers. It raises the issue of user word segmentation and keyword extraction, and searches keyword-related information on the web, and then returns results and saves them to the database, which enables users to extract easily. It is found through the search that the results are more accurate than those before, and the users have more choices.
