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.
