一种基于本体的语义标引方法

A Way of Ontology-based Semantic Indexing

传统的采用主题词和关键词对文档进行标引的方法,由于不能提供语义推理而越来越不适合目前的网络环境。由于本体具有良好的概念层次结构和对逻辑推理的支持,在信息检索领域将有很大的应用价值。本文首先介绍本体的基本概念和领域本体的组成部分,然后提出了一种基于领域本体的语义标引方法,采用本体中的概念对文档进行语义层面的标引,为检索的智能推理提供基础。

The traditional way of document indexing based on subject words and can't work well in the network environment because of the lack of the ability of semantic deducing. Ontology is proving its application value in information retrieval because of its good concept structure and support for logic deducing. In this paper,the basic concept of ontology and the composition of domain ontology are described. A way of semantic indexing based on domain ontology is presented,by which documents can be indexed semantically with the concepts in ontology. The method can be used in intelligent retrieval systems for semantic deducing.
