| 摘 要： | 目前的搜索引擎算法大多是基于关键词搜索,体系上是集中式结构,在安全性和语义性上存在缺陷.基于P2P的结构化半分布式语义搜索算法--DPSS(Distributed P2P Semantic Search),通过研究词与词的关联度,在传统的P2P覆盖语义层,实现语义功能.同时,结合文章距离算法,能够应用在文本分类、文章聚类等领域.

| Abstract: | Most search algorithms nowadays are based on and have a central structure,which may lead to security problems and semanteme absence.A semantic search algorithm based on structured half-distrusted P2P network-DPSS(Distributed P2P Semantic Search) adds a semantic overlay on traditional P2P network and realizes the semantic function through the study of relation degree between words.Meanwhile,combined with the article-distance algorithm,DPSS can be applied to text classifying and text clustering. |
