| 摘 要： | 为了提高知识查询系统的知识服务质量,本文提出了一种基于Ontology的概念联通模型,该模型在知识获取阶段能够对知识进行修正、精简和整合,在知识服务阶段能对原有知识库中的知识进行广泛而有意义的知识重组.本文首先讨论知识本体和概念联通模型,然后分析基于Ontology的概念联通方法,最后给出在知识查询系统中的联通算法.

| Abstract: | To improve the capability of knowledge service in the knlwledge query system, this pqper has proposed an ontology-hasded concept-interconneetion model which can refine and restructure the newly collected knowledge during the phase of knowledge acquisition. Meanwhile, it has proved that this system more needs broadly knlowledge interconnection in the primitive knowledge base. The paper, firstly discusses knowledge ontology and concept model, and then analyzes methods of concept-interconnection, and finally provides three kinds of interconnection algorithms. |
