摘要:
随着移动互联网的逐渐普及,网络社区作为一个虚拟的社交平台,已经逐渐成为了整个社会交际中不可或缺的一部分。如何从一个复杂的社交网站中挖掘出有效的用户信息,越来越成为研究的热点。在这样的背景之下,本文重点研究了基于WAF的用户社区发现,提出了基于词激活力(WAF)模型的用户社区发现方法,将整个复杂网络社区分割成若干个子社区,并使用国内著名微博用户数据进行实验,最后对不同的参数设置对实验结果产生的影响进行了讨论,验证了该算法的有效性。

Based on such kind of background, this paper focus on the WAF based community finding and user recommending. It brings forward an new way to split an whole complex community to several sub communities, based on the word activity force (WAF) model. Then several experiments are designed and carried out on the user information database extracted from twitter and sina microblog, to test the algorithm. Finally, the influence of different paramaters is discussed in detail.
