Sampling Online Social Networks
IEEE Transactions on Knowledge and Data Engineering, 2013As online social networking emerges, there has been increased interest to utilize the underlying network structure as well as the available information on social peers to improve the information needs of a user. In this paper, we focus on improving the performance of information collection from the neighborhood of a user in a dynamic social network. We

Sampling in online social networks
Proceedings of the 29th Annual ACM Symposium on Applied Computing, 2014In this paper, we propose a new graph sampling method for online social networks that achieves the following. First, a sample graph should reflect the ratio between the number of nodes and the number of edges of the original graph. Second, a sample graph should reflect the topology of the original graph.

Homophily in Online Social Networks
2012We develop a parsimonious and tractable dynamic social network formation model in which agents interact in overlapping social groups. The model allows us to analyse network properties and homophily patterns simultaneously. We derive analytical expressions for the distributions of degree and, importantly, of homophily indices, using mean-field ...

Proceedings of the 22nd International Conference on World Wide Web, 2013
One of the main differences between traditional Web analysis and online Social Networks (OSNs) studies, is that in the first case the information is organized around content, while in the second case it is organized around people. While search engines have done a good job finding relevant content across billions of pages, nowadays we do not have an ...

Online social networks in economics
Decision Support Systems, 2009This paper describes how economists study social networks. While economists borrow from other fields like sociology or computer science, their approach of modeling of social networks is distinguished by the emphasis on the role of choices under constraints. Economists investigate how socioeconomic background and economic incentives affect the structure

Vizster: visualizing online social networks
IEEE Symposium on Information Visualization, 2005. INFOVIS 2005., 2005Recent years have witnessed the dramatic popularity of online social networking services, in which millions of members publicly articulate mutual "friendship" relations. Guided by ethnographic research of these online communities, we have designed and implemented a visualization system for playful end-user exploration and navigation of large scale ...

Bring order to online social networks
2011 Proceedings IEEE INFOCOM, 2011Online social networking systems are rapidly becoming popular for users to share, organize and locate interesting content. However, these systems have increasingly been employed as platforms to spread spam and irrelevant content, abusing valuable human attention and service resource. In this paper, we propose a social reputation model to guide users to
