Question Answering System Based on Ontology and Semantic Web
Semantic web and ontology are the key technologies of Question Answering system.Ontology is becoming the pivotal methodology to represent domain-specific conceptual knowledge in order to promote the semantic capability of a QA system.In this paper we present a QA system in which the domain knowledge is represented by means of Ontology.In addition,a Chinese Natural Language human-machine interface is implemented mainly through a NL parser in this system.An initial evaluation result shows the feasibility to build such a semantic QA system based on Ontology,the effectivity of personalized semantic QA,the extensibility of ontology and knowledge base,and the possibility of selfproduced knowledge based on semantic relations in the ontology.And experiments do prove that it is feasible to use the method to develop a QA System,which is valuable for further study in more depth.
