摘要
从物理学中场的思想出发,将论坛、博客等舆情事件的讨论平台看作一个舆情场,引入观点势函数描述舆情场内各网民间观点的相互吸引作用,基于各网民的时变观点状态建立有向的网民观点吸引网络,通过寻找具有高观点吸引势的网民节点实现舆情事件意见领袖的发现;该算法能有效避免传统的基于链接或回复关系的意见领袖发现算法中网民连接的依赖关系不明确的缺点。
Inspired by the idea of physical fields, the discussion platform of each blog or public opinion event is regarded as an opinion field, an opinion attraction potential function is used to describe the interactive attraction from all net citizens in a public opinion field, the directional opinion attraction network of the net citizens is established based on the time-variant point state of the cyber citizens, and then the opinion leader is discovered by detecting the nodes of the net citizens with high attraction potential. This algorithm can effectively avoid the disadvantages of dependency relationship indeterminacy among the net citizens in traditional opinion leader discovery algorithm based on link or reply relation.
