基于语义关键词的本体特征指数获取方法研究

Research on How to Get Ontology Index Based on Semantic Keywords

本体作为知识表达的范例工具,依赖于语义来进行逻辑推理。但在本体搜索时依赖于语义进行搜索十分困难。针对当前本体搜索中存在的问题,提出了一种通过拆分概念来获取语义关键词进而通过计算权值来获得一组本体特征指数的方法。详细阐述了如何获取本体的一组特征指数,即能够描述本体的一组相关的关键词。

Ontolngy, as a tool for representation of knowledge, relies on semantics to perform logic inference. However searching an ontology is difficult to manipulate semantics. The method of unfolding concepts of ontology to get a set of keywords with semantics and then computing the weight - value of the keywords to acquire the ontology index is proposed in this paper. How to get the ontology index that a set of keywords which can describe the ontology content and semantic relation is detailed described. The keywords acquired from the methods can instruct the work of ontology searching and constructing.
