Title: Study on generation and match of question answering ontology
Abstract: Aiming at the requirements and traits of question answering systems,designed a structure of question answering ontology,which was the representation of natural language questions,and provided a well retrieval mechanism.Meanwhile,proposed an approach of ontology acquisition,which could decrease the costs of development manually.Finally,proposed formula in order to computer semantic similarity between sentences basing on question answering ontology.Now,the proposed ontology has already been implemented and applied in the natural language oriented Web answer system(NL-WAS),it shows that the question answering ontology can improve the result of the question search of NL-WAS system effectively.
