摘要
本文针对web数据挖掘中,具有动态性和不确定性语义web所存在的问题,基于单向S-粗集,提出S-粗语义和S-粗语义概率的概念,对粗语义、S-粗语义、粗语义概率和S-粗语义概率的特性进行了讨论,并给出了应用。利用语义web的概率特性,S-粗语义概率能够更好地描述web数据挖掘中具有动态特性的不确定性语义web问题。
For the problems of the dynamics and uncertainty of web semantics existing in web data mining,the concepts of S-rough semantics and S-rough semantics probability based on one direction S-rough sets are presented,the discusses of characteristic and the applications are obtained for rough semantics,S-rough semantics,rough semantics probability and S-rough semantics probability.Through using the probabilistic characteristic of semantic web,the problems of the dynamics and uncertainty of web semantics existing in web data mining are described preferably by S-rough semantics probability.
