摘要
信息检索是当今社会的热点话题,但是一般的搜索引擎涵盖面太广,个性化、专业化程度不够。本文利用潜在语义索引(LSI)的最新技术SDD(半离散矩阵分解)算法来解决大规模网页索引计算的问题,利用SDD算法建立起语义索引,成功构建了一个中文农业搜索引擎,本文介绍了"农搜"系统的结构、功能、关键算法和应用情况。
Information retrieval is a hot topic in today's society, but the general coverage of the search engine is too wide to personalized and professional enough. Through the use of the latest technology SDD (semi-discrete matrix decomposition) algorithm of latent semantic indexing (LSI) to solve the massive problem of calculating the index page, the use of SDD to establish semantic indexing algorithm, a Chinese agriculture search engine was successfully built. The structure, function and application of the key algorithm of agricultural search system were introduced.
