摘要
介绍了语义网,本体以及语义标注的基本概念,对现有的语义标注方法以及技术进行了说明和分析。针对目前互联网上含有大量语义信息的HTML文档,提出了一种自动化的语义标注的方法。该方法对HTML文档进行结构分析,并参照词汇数据库Hownet和领域本体对文档进行语义分析,找出文档对应的语义分类树,给文档加上语义标签。以电子消费品领域的HTML文档为实验对象,实验结果证明了该方法具有一定的可行性。
The basic concept of semantic Web,ontology and semantic annotation are described.Then the semantic annotation technology and tool today are introduced and analyzed,and a way of automatic semantic annotation based on HTML documents that contain rich semantic data on the Web is presented.This method couples structural analysis of documents with semantic analysis incorporating domain ontologies and lexical database Hownet,discovers the semantic partition tree corresponding to documents,and annotates HTML documents with semantic lables.The experiment is based on the HTML documents of electronic products,the result shows the method is feasible.
