网络信息检索环境下的语义检索研究

Research on Semantic Retrieval in Network Information Retrieval Environment

互联网给用户的信息检索带来便利的同时也导致大量冗余信息出现,使得检索效率低下。语义检索通过对用户检索要求的语义分析使得检索效率以及检索准确度大大提升。本文在分析语义检索基本要素和检索原理的基础上,介绍三种常用的语义检索系统,体现语义检索在网络信息检索环境下的优势。

The Internet has brought convenience to the users＇ information retrieval, but also led to a large number of redundant information, resulting in inefficient retrieval. Semantic retrieval makes retrieval efficiency and retrieval accuracy greatly enhanced through semantic analysis of the requirements of the users to retrieve. Based on the analysis on basic elements of semantic retrieval and retrieval principle, this paper describes three common semantic retrieval systems, which embodies the advantages of semantic retrieval in network information retrieval environment.
