CDQA: An ontology-based question answering system for Chinese delicacy

The problem that information stored in semantic web is hard to access is becoming more and more obvious, and the characteristics of question answering make it have a bright prospect. This paper presents an ontology-based Chinese delicacy question answering system named CDQA. We first proposed a new query triple representation to model complex questions with multiple modifications and clauses. Then a general method for transforming Chinese question into query triple representation was presented. Finally CDQA proposed a stepping searching method, which can better control the search process. Experiment results showed that CDQA can get a good performance.
