基于Lucene的语义检索系统

Semantic Retrieval System Based on Lucene

在一种基于LUCENE的传统文本检索引擎之上,采用C/S架构模式的语义检索实验系统。用户可以根据需要,从客户端向服务器提交相应的查询信息配置,服务器根据此配置,通过本体导航与同义词查询2种查询扩展优化技术,对提交的查询关键词组进行查询、扩展等优化处理后,将经优化处理过的查询关键词组导入传统的文本检索引擎中,对文档资源进行匹配,将查询结果根据用户要求的排列,并依次返回给用户。通过用户与服务器的信息交互与对查询语句的查询扩展,该系统提高了查准率与查全率。

With a traditional text search engine which is based on Lucene, this paper describes a semantic search experimental system which uses C/S pattern. In the system, user sets the configuration which will be passed to the server according to user＇s wants, and the server operates the query keywords which is submitted by user with ontology navigation and synonym searching according to these configuration, enters these optimized query keywords into traditional text search engine for searching the result, and returns these results to client in the order defined by user. This system uses the interaction between the client and the server, and query expanding trying to raise rate of precision and recall of the retrieval system.
