基于本体的受限领域文本信息提取方法

Information Extraction Method of Limited Area Based On Ontology

针对指挥信息化模拟训练系统中自由格式报文转换问题,根据仿真驱动信息的需求,讨论了对自由格式报文进行信息提取的实现方法。在受限领域(军事领域)中引入本体概念,构建了领域本体模型及语法规则,提出了基于本体的信息提取方法,采用可扩展标记语言(eXtensible Markup Language,XML)和VC++.NET技术相结合,实现对文书的信息提取,为进一步的数据转换和应用奠定了基础。

Aiming at data conversion for non-formatted message in simulated training system of command informatization, this paper discusses an information extraction method from non-formatted message according to the demand of simulation-driven information. The paper builds the domain ontology model and the syntax rules after the ontology concept is introduced into the limited area （ military area） and proposes the information extraction method based on the ontology. With the technical support of eXtensible Markup Language （XML） Schema and VC ＋ ＋. NET, the method achieves information extraction in practice. It lays foundation for data conversion in the actual simulation work.
