Introduction to Social Network Analysis

Instructor: Anuška Ferligoj, University of Ljubljana

Time: 13.00-16.00 July 17th 2017

Course Description:

Social network analysis has attracted considerable interest from social and behavioral science community in recent decades. Much of this interest can be attributed to the focus of social network analysis on relationship among units, and on the patterns of these relationships. Social network analysis is a rapidly expanding and changing field with broad range of approaches, methods, models and substantive applications. In the course, special attention will be given to:

1. General introduction to social network analysis:

  • What are social networks?
  • Data collection issues.
  • Basic network concepts: network representation; types of networks; size and density.
  • Walks and paths in networks: length and value of path; the shortest path, k-neighbours; acyclic networks.
  • Connectivity: weakly, strongly and bi-connected components; contraction; extraction.

2. Overview of tasks and corresponding methods:

  • Network/node properties:  centrality (degree, closeness, betweenness); hubs and authorities.
  • Cohesion: triads, cliques, cores, islands.
  • Partitioning: blockmodeling (direct and indirect approaches; structural, regular equivalence; generalised blockmodeling); clustering.
  • Statistical models.

3. Software for social network analysis (UCINET, PAJEK,…).
