ACQA_onto: An ontology approach for restrain domain question answering system

This paper presented a restrained domain ontology model for agriculture cultivation question answering system - ACQA_onto. The question answering system (QA) has become one effective approach for knowledge engineering research. Ontologies could make the restrain domain concepts of semantics being understood by computer, which have been one significant technique for question answering system. This paper provided introduction ontologies in general and subsequently, in particularly, shortly provided the definition of domain ontology for agriculture cultivation. In main part, this paper presented the restricted domain ontology models and concept level vector space model of information retrieval (IR). The ontological representations of documents for agriculture cultivation question answering system was presented, and descript the prototype of ACQA_onto, in which part focalized with the process of generating answers from question. The result of ACQA_onto was proposed and the future work of question answering system for agriculture cultivation was introduced briefly.
