Abstract: Existing Question-Answering systems for the Web focus on source of text.The Web Ontology Language(OWL) is recommended by W3C as the standard for knowledge representation and exchange on the Internet in 2004.So QA based on OWL knowledge becomes an important research.A QA system named Agile was presented in this paper,and the detail schemes of formulating questions and indexing OWL were described.In order to acquire mapping unit,Agile defined two data structures for formulating questions and OWL and formatted them through existing natural language processing technology and OWL parsing method.Agile is auto and can deal with more kinds of questions than former QA based on OWL systems.

Key words: Question-answering,OWL knowledge,Formulating questions,Building dictionary
