Introduction to social network methods

Table of contents


About this book

This on-line textbook introduces many of the basics of formal approaches to the analysis of social networks.  The text relies heavily on the work of Freeman, Borgatti, and Everett (the authors of the UCINET software package). The materials here, and their organization, were also very strongly influenced by the text of Wasserman and Faust, and by a graduate seminar conducted by Professor Phillip Bonacich at UCLA.  Many other users have also made very helpful comments and suggestions based on the first version.   Errors and omissions, of course, are the responsibility of the authors.

You are invited to use and redistribute this text freely — but please acknowledge the source.

Using Metadata to Find Paul Revere

Um exemplo de um estudo de redes sociais

Um exemplo de um estudo de redes sociais

It’s just metadata. What can you do with that? Kieran Healy, a sociology professor at Duke University, shows what you can do, with just some basic social network analysis. Using metadata from Paul Revere’s Ride on the groups that people belonged to, Healy sniffs out Paul Revere as a main target. Bonus points for writing the summary from the point of a view of an 18th century analyst.

What a nice picture! The analytical engine has arranged everyone neatly, picking out clusters of individuals and also showing both peripheral individuals and—more intriguingly—people who seem to bridge various groups in ways that might perhaps be relevant to national security. Look at that person right in the middle there. Zoom in if you wish. He seems to bridge several groups in an unusual (though perhaps not unique) way. His name is Paul Revere.

You can grab the R code and dataset on github, too, if you want to follow along.

How to: network animation with R and the iGraph

Construir animações de iformação relacional com R

Construir animações de informação relacional com R

This article lists the steps I take to create a network animation in R, provides some example source code that you can copy and modify for your own work, and starts a discussion about programming and visualization as an interpretive approach in research. Before I start, take a look at this network animation created with R and the iGraph package. This animation is of a retweet network related to #BankTransferDay. Links (displayed as lines) are retweets, nodes (displayed as points) are user accounts. For each designated period of time (in this case, an hour), retweets are drawn and then fade out over 24 hours.

Introduction to Diagrams

Uma bela introdução aos grafos

Uma bela introdução aos grafos

Diagrams are everywhere — from the established conventions of highway signs to the newly emerging visualizations appearing on social networking websites.  Most people have a personal experience of diagrams whether drawing directions or figuring out how to operate a new computer. Yet very few people are familiar with how we read or construct diagrams.

This short film introduces the language of diagrams and their role in visual thinking and communication. As only a film can do, it reveals the vocabulary “in the wild” and in the context of making and using diagrams.
