Introduction to Social Network Analysis

Abstract

Social Network analysis focuses on patterns of relations between and among people, organizations, states, etc. It aims to describe networks of rela- tions as fully as possible, identify prominent patterns in such networks, trace the flow of information through them, and discover what effects these relations and networks have on people and organizations. Social network analysis offers a very promising potential for analyzing human-human interactions in online communities (discussion boards, newsgroups, virtual organizations). This Tuto- rial provides an overview of this analytic technique and demonstrates how it can be used in Human Computer Interaction (HCI) research and practice, focus- ing especially on Computer Mediated Communication (CMC). This topic ac- quires particular importance these days, with the increasing popularity of social networking websites (e.g., youtube, myspace, MMORPGs etc.) and the research interest in studying them.
