| 摘 要： | 作为语义网基础的本体能够描述特定领域的概念及其关系,为用户查询相关概念、文件提供了方法,那么有效地构建本体成为应用本体的关键问题.但经过分析,目前的本体查询系统存在着缺陷,本文提出基于形式概念分析构建本体查询系统,解决寻找领域中隐含概念困难的问题.为了使检索的内容符合用户的喜好,提出在概念模型中加入用户的评分机制,从而提高信息查找的效率,最后通过一个实例证明该本体查询系统的有效性.

| Abstract: | As the foundation of the semantic web, ontology describes the concept and relation of domain knowledge and provides a way for users to search relevant documents and concepts. It becomes an important problem on ontology application to build ontology. However, there are some defects between existing ontology search systems in many aspects. This paper finds connotative concept by applying formal concept analysis theory to construct ontology search system. User of scoring mechanism in concept model is proposed ... |
