Taking advantage of the semantic expression in Chinese FrameNet(CFN),this paper discusses the construction of the domain specific Chinese FrameNet semantic base using owl,and validate and analyze its effectiveness by the design of Question Answering System in the transportation domain.In the proposed QA system,the query questions are first classified by a combination of the TREC categories and the ontology categories.Then we propose a question analysis strategy based on the CFN,aiming at the triple of the question: Semantic predicate,semantic subject and semantic object.On the basis of the CFN semantics analysis,the answer is extracted from the tourism ontology base.This approach is implemented by the ontology editor Protege,and the experiment proves the validness of this method.
