摘要
经分析研究开源的Lucene系统架构以及特殊xml数据源,针对Lucene搜索得分公式的不足,提出了结合词项位置和二次检索的公式,设计一种文本搜索系统;并以提高检索性能、相似性搜索的准确率、索引的空间效率和支持查询的时间效率为目标进行实验,最后通过部署Tomcat服务器实现.经实验验证,改进的系统较之于原Lucene系统提高了建立索引效率、查询效率、准确率.
On the basis of analysis and study on the open source Lucene system architecture, a semantic search system is designed based on the special XML data sources in this paper. What＇s more, we use the word item location and word semantic to improve the Lucene＇s search results and conduct experiments to test and verify the retrieval performance, the accuracy of similarity search, the space efficiency of index and the time-efficiency of supporting inquiry： And finally by deploying the Tomcat server to implement our implement system. The experiment results prove that compared with the original Lucene indexing system, our system can improve the indexing efficiency, query efficiency and accuracy.
