Chinese question answering system Based on the Chinese FAQ

Abstract

Sentence similarity computation is a key part of the Chinese FAQ system and the computation accuracy determine the quality of the system. Combining with question classification index, a new Chinese sentence similarity computing method based on Content Forward Network is proposed. The method combined concept semantic matching and the overall semantic question sentence similarity computation with question automatic classification to deal with the sentence similarity computing. Comparing with the traditional keyword-based and simple semantic question similarity computation method, Chinese frame semantic information makes the Chinese sentence similarity calculation accuracy improved obviously. The experimental results show that the method can effectively solve the intelligent matching problem in Chinese question answering system.
