Gossip: Identifying Central Individuals in a Social Network GOSSIP: IDENTIFYING CENTRAL INDIVIDUALS IN A SOCIAL NETWORK

Is it possible, simply by asking a few members of a community, to identify individuals who are best placed to diffuse information? A model of diffusion shows how members of a community can, just by tracking gossip about others, identify those who are most central in a network according to “diffusion centrality” – a network centrality measure that predicts the diffusion of a piece of information...

Identifying Peer Influence Effects in Observational Social Network Data: An Evaluation of Propensity Score Methods

There is widespread scientific and practical interest in estimating peer influence effects for a variety of behaviors, but peer influence effects are not identifiable in most observational data. Social scientists have thus had to remain largely silent on these effects — or make inconclusive or misleading arguments for their estimates of them. The state-of-the-art research has used propensity sc...

Identifying First Responder Communities Using Social Network Analysis

First responder communities must identify technologies that are effective in performing duties ranging from law enforcement to emergency medical to fire fighting. We aimed to create tools that gather and assist in quickly understanding responders’ requirements using semantic technologies and social network analysis. We describe the design and prototyping of a set of semantically-enabled interac...

Identifying Node Role in Social Network Based on Multiple Indicators

Because a single indicator is not sufficient to analyze multiple characteristics of a node, it is a natural solution to apply multiple indicators that should be selected carefully. An intuitive idea is to select some indicators with we...
