The development of social networks has not only improved the online experience, but also stimulated the advances in knowledge mining so as to assist people in planning their offline social events. Users can explore their favorite events, such as celebrations and symposiums, through the pictures and the posts from their friends on social networks. An effective event recommendation can offer great convenience...
Linked data consist of both node attributes, e.g., Preferences, posts and degrees, and links which describe the connections between nodes. They have been widely used to represent various network systems, such as social networks, biological networks and etc. Knowledge discovery on linked data is of great importance to many real applications. One of the major challenges of learning linked data is how...
Dynamic networks are structures with objects and links between the objects that vary in time. Temporal information in dynamic networks can be used to reveal many important phenomena such as bursts of activities in social networks and human communication patterns in email networks. In this area, one very important problem is to understand dynamic patterns of object roles. For instance, will a user...
In the context of endogenous network formation, we study strategic interaction among players within k-neighborhood. Based on the myopic best response rule, players choose action and establish links with other players by unilaterally investing in costly pair wise links in the evolution of networks. First, we characterize the equilibrium networks and describe the impact of the link cost on the equilibrium...
Most people have multiple accounts on different social networks. Because these networks offer various levels of privacy protection, the weakest privacy policies in the social network ecosystem determine how much personal information is disclosed online. A new information leakage measure quantifies the information available about a given user. Using this measure makes it possible to evaluate the vulnerability...
