摘要
隐含语义检索 ( Latent Semantic Indexing,LSI)是一种基于概念的文献检索方式。它区别于传统的基于用户查询条件与文档的单词匹配的文献检索方法 ,根据文档与查询条件在语义上的关联而向用户提交查询结果。本文介绍了隐含语义检索在文献检索中的一种实现方法 。
LSI(Latent Semantic Indexing), which is a method of concept-based retrieval, is different from traditional retrieval which depend on a lexical match between words in user's query and those in documents. LSI can make retrieval accomplished based on the queries and documents meaning relationship. It is a completely automatic yet intelligent method in English textual materials indexing.
