搜索引擎新思维

New Method to Organize Information Resources on Network

网络资源正在以指数级的速度增长 ,如何更好地组织这些信息变得越来越重要。本文在分析和评价现有搜索引擎的两种组织方法 ,即关键词索引和等级式主题索引的基础上 ,提出了一种新型的索引组织方法——联合索引 ,它有机地把前两种组织方法结合了起来 ,充分发挥了它们各自的优点。这种方法的基本思路为 :以《中国分类主题词表》为基础 ,精选主题词 (或主题词串 ) ,并把它们按学科等级关系建成一棵棵主题词树 ,然后把由索引软件所抽取的关键词 ,根据语义关系(主要是同义词关系 )与相应的主题词联结起来 ,以实现充实等级式主题索引工作的自动化和关键词索引的高级智能检索。

The information resources on network is increasing rapidly. How to org anize these resources better becomes more important. On the foundation of analyz ing and evaluating two existing index methods of search engine-keyword index an d hierarchical subject index, this paper puts forward one new method-united ind ex, which unites the two forenamed indexes completely, exerts sufficiently stron gpoint of them. Its central thought is : on the foundation of 《China Classifica tion-Subject Corresponding Table》,handpick subjects, and build subject trees ac cording their discipline hierarchical relations; then link keyword extracted b y automatic index software to corresponding subject according their semitic rel ations. The united index would automate enrich work of hierarchical subject inde x and make advanced intelligence search of keyword come true.
