基于语义网络的概念检索研究与实现

Semantic Network Based Concept Retrieval

本文介绍一种基于语义网络的中文搜索引擎概念检索模型 ,并应用此模型 ,针对计算机及其应用领域 ,创建了一个含有 50 0多个概念节点 ,包括一个分类体系和近 3 0 0种概念相关关系的语义网络 ,初步实现了特定领域的概念检索。实验结果表明 ,该模型对于建设知识化、智能化的中文搜索引擎是非常有用的。

We introduce a kind of semantic network based concept retrieval model for Chinese search engine in this paper.Then we apply this model into the restricted domain of computer and its applications.We have built a semantic network containing over 500 concept nodes,a classification system and almost 300 kinds of concept relations to implement a search engine for special domain.Experiment results have suggested that this model is very useful for knowledgeable and intelligent Chinese search engine.
