摘　　要：为了提高语义检索的查准率和查全率,进行语义检索优化设计,提出一种基于多线程粒子边缘表达的语义检索优化算法,构建语义检索多线程任务调度平台,在平台中进行语义概念树构建,优化搜索引擎对文本特征的搜索敏感度,设计多线程粒子边缘表达算法进行语义特征分析,实现语义的多线程粒子边缘表达离散度增强,提高检索性能。仿真结果表明,采用该方法能提高语义检索的查全率和查准率,检索时间缩短,性能优越。The semantic retrieval optimization design is performed to improve the retrieval precision and recall, this paper puts forward a semantic retrieval optimization algorithm based on multithreaded particle edge expression. The semantic retrieval multithreading task scheduling platform is designed in which the semantic concept tree is set up and the search sensitivity of search engine for text feature is optimized. The nmltithreaded particle edge expression algorithm is designed to perfoml semantic feature analysis, improve multithreaded particle edge expression separation of semantics and enhances the retrieval performance. The simulation results show that this method can improve the retrieval precision and recall, shorten the retrieval time and enhance the performance.
