摘要
针对Web社会网络中个体及个体关系均存在一定的不确定性,以及个体及其关系具有属性不确定的实际问题,综合不确定图和属性图特征,提出"不确定属性图"概念,并对其进行属性描述。分别给出边不确定属性图、顶点不确定属性图以及顶点和边均不确定属性图概念,证明了它们与属性图、不确定图之间的关系和它们自身的性质;在考虑结点和边属性也可能存在不确定的情况,给出不确定属性图的综合模型,证明不确定图和属性图是不确定属性图的特例,不确定属性图是二者的拓展研究;最后文中给出不确定属性子图及其判定方法。分析表明,不确定属性图更能反映Web社会网络的真实结构。
Because relationship between the individual and the individual exists uncertainty, and this is practical problem that individual and its relationship is attribute uncertainty in the Web social network . This paper proposed ＂not sure attributes graph＂ concept and made discription. This paper respectively gives these concepts. There are edges uncertainty attribute graph, vertices uncertainty attribute graph, edges and vertices are uncertainty attributes graph. This paper gives uncertainty attribute graph comprehensive model in considering uncertain of the vertices and edges attributes and it proved their nature and their relationship with attribute graph, uncertainty graph. Uncertainty attribute graph is development research of attribute graph and uncetain graph. At last the paper gives t^e concept of uncertain attribute subgraph and its determination method. Analysis shows that, uncertain attribute graph can reflect the real structure of the Web social networking.
