Research on Semantic Retrieval in Network Information Retrieval Environment

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.
