作为一种能够在语义层和知识层上描述信息系统的概念建模工具,本体在许多领域得到了广泛应用。由于本体的构建和维护工作费时费力,本体的构建方法研究成为了实现语义Web应用的最重要技术。综述了从不同的结构化信息源(数据库、XML文档以及Web表格)构建本体的方法,进行了详细分析与对比,并给出其存在的不足之处以及未来可能的研究方向。
Ontology is a tool for modeling concept of information systems on the semantic and knowledge layer,and is widely employed in many areas.Since building and maintenance of ontologies must cost much time and energy,research on ontology building method becomes the most important technology for realizing semantic Web applications.This paper surveyed the methodology for constructing ontologies from different structured information sources(database,XML document,Web table),analyzed and compared with each other.And,it pointed out some remaining defects and future research directions.
