Personal willingness is one of the most important factors influencing the construction of social community and the information dissemination in social network.In this paper

we propose a social community structure and information detection scheme based on personal willingness in social network.In our proposed scheme

the social community detection algorithm uses the node attributes to detect social community structure and further find overlapping communities;the information dissemination method is based on the exponential model

which constructs the feature vector by the edge feature and the node feature

the willingness vector by the personal willingness and the community willingness

and the basic relationship by the dissemination probability and dissemination delay.Experimental results show that our proposed scheme can ensure the effectiveness of social community detection and the initiative and reliability of information dissemination.
