摘　　要：问答系统因能提供方便的输入模式与更精确的答案而成为获取网络信息的重要手段。介绍了一个面向OWL知识的问答系统Agile,并着重阐述了其在问题规范和字典生成方面的技术方案。为了得到合适的映射单位,Agile定义了两个数据结构用于规范自然语言问题和OWL本体知识字典,并借助一些自然语言处理工具和OWL解析工具将两种源知识进行了形式化。和现有网络问答系统比较,Agile不需要用户参与,能够处理的问题领域和形式更加丰富。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 lan- guage processing technology and OWL parsing method. Agile is auto and can deal with more kinds of questions than former QA based on OWL systems.
