Identifying sets of key players in a social network

نویسنده

  • Stephen P. Borgatti
چکیده

A procedure is described for finding sets of key players in a social network. A key assumption is that the optimal selection of key players depends on what they are needed for. Accordingly, two generic goals are articulated, called KPP-POS and KPP-NEG. KPPPOS is defined as the identification of key players for the purpose of optimally diffusing something through the network by using the key players as seeds. KPP-NEG is defined as the identification of key players for the purpose of disrupting or fragmenting the network by removing the key nodes. It is found that off-the-shelf centrality measures are not optimal for solving either generic problem, and therefore new measures are presented.

Identifying Opinion Leaders Using Social Network Analysis, a Study in an Egyptian Village

This research used four approaches to identify opinion leaders in two networks in an Egyptian Village. One approach was used for identifying single opinion leaders (network centrality measures), and three approaches were used to identify sets of key players (group centrality, network efficiency, and KPP-Pos & KPP-Neg). Social network analysis software (UCINET 6) was used for individual & group ...

A Centrality Approach to Identify Sets of Key Players in an Online Weblog

Social Network Analysis (SNA) is an active area of research, not only in inter – disciplinary areas but also in multidisciplinary areas. Key players can be identified using different methodologies, including centrality measures. Few works are done using different datasets in different areas. In this paper, we tried to identify the sets of key players from blog posts ad responses that are posted...

Analysis of Media Consumption Behavior of Sports Fans with a Network Approach

Fans like to talk about their favorite team and players with others. Professional team fans use social media to learn more about teams, connect with other fans, follow teams and players, and build a fan community. Social media by creating a network of users has become a platform for researchers to study fan behavior. Given that members of the fan community interact with each other, their opinio...

An Information Theory Approach to Identify Sets of Key Players

This paper presents an application of information theory to identify sets of key players in social networks. First, we define two entropy measures that we use to analyze the structural properties of a social network. Then, we propose a new method aimed at finding a set of key players that solves the KPP-Neg and KPP-Pos problems. Our preliminary experimental results indicate that the entropy mea...
