摘要
信息抽取研究旨在为人们提供更有力的信息获取工具,以应对信息爆炸带来的严重挑战。Ontology作为领域知识的共同理解,能有效地解决现在信息抽取所面临的主要挑战——知识工程的瓶颈问题。文中详细介绍了本体的定义和建模语言,分析了现有基于本体信息抽取的几种典型方法,得出了其所存在的主要问题。
The research on information extraction aims at providing more powerful information access tools to help people overcome the problem of information overloading. As the common knowledge of a special domain,ontology could deal with the challenging task in information extraction.the bottleneck of knowledge engineering. In this paper, presents the definition and modeling language in detail. And discusses the popular methods used in information extraction based on ontology. At last put forward some problems in those systems.
