Efficiency of node position calculation in social networks

Abstract

Social network analysis offers many measures, which are successfully utilized to describe the social network profile. One of them is node position, useful to assess the importance of a given node within both the whole network and its smaller subgroups. However, to analyze large social networks a lot of effort and resources are necessary. In this paper, some algorithms that can be utilized in the process of node position evaluation are presented and their efficiency is tested. In particular, three distinct algorithms were developed and compared: PIN Edges, PIN Nodes, and PIN hybrid. © 2009 Springer Berlin Heidelberg.
