基于领域本体的元搜索引擎的研究

Research of Meta Search Engine Based on Domain Ontology

随着Internet的迅速发展,加速了人类进入信息社会的步伐,网络信息量迅猛膨胀,几乎每时每刻都在产生大量的信息,人们需要快速从海量的信息资源中查找到合适的信息,网络的搜索引擎便发展起来。但由于搜索技术的限制,查准率和查全率都不是很高。本文基于搜索引擎的现状,提出新的搜索引擎的模型,介绍了系统的工作原理,通过对系统的测试评估,该系统实现了对关键字的同义词和英文的扩展搜索,使搜索结果得到有效优化。

With the rapid development of Internet,it accelerated the pace of entering the information society.The information on the network becomes more and more comprehensive,and it produces a lot of information in every minute.People need to find the appropriate information from mass information,so the search engine emerges in the network.But as a result of search technology limits,the precision ratio and recall ratio are not satisfied.This paper,based on the current web search engine,puts forward a new model of search engine based on domain ontology,introduces the working principle of the system.The system realizes the key word synonym and English expansion inquiry,and enhances the recall and the precision.
