On the Non-Progressive Spread of Influence through Social Networks
Non-Progressive Social Networks
2011/9/14
The spread of in uence in social networks is studied in two main categories: the progressive model and the non-progressive model (see e.g. the seminal work of Kempe, Kleinberg, and Tardos in KDD 2003)...
Characterizing the process of reaching consensus for social systems
Characterizing social systems
2011/9/8
A novel way of characterizing the process of reaching consensus for a social system is given. The foundation of the characterization is based on the theorem which states that the sufficient and necess...
Understanding how far information, behaviors, or pathogens spread in social networks is an important problem, having implications for both predicting the size of epidemics, as well as for planning e e...
Sybil accounts are fake identities created to unfairly increase the power or resources of a singlemalicious user. Researchers have long known about the existence of Sybil accounts in online communitie...
A Game Theoretical Approach to Broadcast Information Diffusion in Social Networks
Social Network, Game Theory, Knowledge,Popularity, Trust, Reputation, Rumor.
2011/9/15
One major function of social networks (e.g., massive online social networks) is the dissemination of information, such as scientific knowledge, news, and rumors. Information can be propagated by the u...
Modeling Social Networks with Node Attributes using the Multiplicative Attribute Graph Model
Modeling Social Networks Node Multiplicative Attribute Graph Model
2011/9/15
Networks arising from social, technological and natural domains exhibit rich connectivity patterns and nodes in such networks are often labeled with attributes or features. We address the question of ...
Human as Real-Time Sensors of Social and Physical Events: A Case Study of Twitter and Sports Games
Real-Time Sensors Social Physical Events Twitter Sports Games Case
2011/9/14
In this work, we study how Twitter can be used as a sensor to detect frequent and diverse social and physical events in real-time. We devise efficient data collection and event recognition solutions t...
Co-evolution of Selection and Influence in Social Networks
Selection and Influence Social Networks
2011/9/14
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network(link structure) can change with time. We propose a
model of co-evolving networks where both nod...
Composite Social Network for Predicting Mobile Apps Installation
Social Network Mobile Apps
2011/9/9
We have carefully instrumented a large portion of the population living in a university graduate dormitory by giving participants Android smart phones running our sensing software. In this paper, we p...
