基于SDD算法的中文农业搜索引擎设计与实现

Design and Implementation of Chinese Agricultural Search Engine Based on SDD

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。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。

Information retrieval is the hot topic of our society, but almost every search engine covers too many content, so that they are not very specific. In the paper, we introduce a new technology ofLSI o SDD （Semi-discrete decomposition of matrix ） improve the SVD and can use in large scale o We index the webs based on SDD with the specific dictionary, and make a specific search engine of agriculture .
