农业知识检索系统的研究与实现

Research and Realization of Agricultural Knowledge Retrieval System

基于农业知识数据库,提出了农业知识检索系统的架构;结合湖南省农业知识数据库的特色,改进了基于向量空间模型建模的排序算法和归一化计算排序算法。测试表明,系统设计和检索算法的精度均达到了预期要求。

Based on agricultural knowledge database,the Framework of the knowledge retrieval system for agricultural is presented.base system for agricultural is presented.Combining Hunan＇s agriculture characteristics,the author has improved the modeling algorithm of vector space models,LMS Algorithm.Finally,the experiment explains that the system design and the accuracy of sorting algorithm all satisfies the requirements for agricultural information service platforms.
