基于本体的Web搜索引擎框架

Web Search Engine Framework Based on Ontology

本文提出了一个基于多本体的搜索引擎框架，分析了本体、智能代理程序、搜索引擎本身在框架中的作用和工作模式。同时，针对互联网并构本体的查询问题，提出了一个分布式多本体查询的模型。引入本体技术后，web搜索引擎的工作方式由关键词全文检索转为知识检索，从而增强了搜索引擎处理复杂查询的能力。

This paper introduce a search engine framework based on ontology, and analysis the function and the working mode of ontology, agent and SE itself in this framework.Meanwhile,this paper presents a distributed multi-ontology retrieval method to process a query of heterogeneous ontology on the intemet.With ontology, search engine （SE）convert its working mode from full-text retrieval based on key words to Knowledge retrieval, and enhance SE ability for dealing a complicated query.
