Opinion formation in time-varying social networks: The case of Naming Game
Opinion formation time-varying social networks The case of Naming Game Social and Information Networks
2012/4/19
We study the dynamics of the Naming Game as an opinion formation model on time-varying social networks. This agent-based model captures the essential features of the agreement dynamics by means of a m...
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)...
Highly Nonlinear Ising Model and Social Segregation
Ising Model, Modified Ising model, statistical physics, urban segregation
2011/9/7
The usual interaction energy of the random field Ising model in statistical physics is modified by complementing the random field by added to the energy of the usual Ising model a nonlinear term S n ....
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...
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...
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...
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...
Model of Opinion Spreading in Social Networks
opinion spreading, social networks, data mining, influencers
2011/8/29
A computer mediated social network is a modern information system where data is generated, distributed, evaluated and accumulated. It is important to understand how the topology of the network affects...
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...
The Emergence of Leadership in Social Networks
Minority Game, Social Networks, Emergent Power Laws
2011/8/26
We study a networked version of the minority game in which agents can choose to follow the choices made by a neighbouring agent in a social network.We show that for a wide variety of networks a leader...
Being Rational or Aggressive? A Revisit to Dunbar's Number in Online Social Networks
Being Rational Dunbar's Number Social Networks
2010/11/17
Recent years have witnessed the explosion of online social networks (OSNs). They provide powerful IT-innovations for online social activities such as organizing contacts, publishing contents, and shar...
Evolution of Coordination in Social Networks: A Numerical Study
Social Networks Numerical Study
2010/11/16
Coordination games are important to explain efficient and desirable social behavior. Here we study these games by extensive numerical simulation on networked social structures using an evolutionary a...
