#R #Temporal Networks #igraph

Temporal networks with R and igraph (updated)

A while ago, I wrote a post about how to create animations of temporal networks using R and the amazing package igraph package. The post was written in 2012 and the code does not work with the most recent versions (1.0) of igraph. Here I revisited that post, improving its performance and also making it consistent with the new versions of the package and R. First of all, let me remind you the basic idea: we want to get an animated evolution of a network in which nodes/edges appear (and/or disappear) dynamically. ...

#Netmob #Mobile phone data #Conferences

Netmob 2015

I had the pleasure to organize last edition of Netmob at MIT Media Lab (together with Sandy Pentland, Vincent Blondel and Yves-Alexandre de Montjoye). Netmob is the primary conference in the analysis of those datasets in social, urban, societal and industrial problems. Netmob 2015 also hosted the final part of theD4D Challenge by Orange. They were 3 amazing days of applications and analysis of mobile phone datasets, preceded by one-day school and 3 days Hackathon. ...

Best papers of the 2013. What is privacy?

I have read around 200 papers this year. A large fraction of them were very technical, some reviews and other very fashionable. But among them, I would like to highlight the ones that for me are the best. This is a personal selection and it is based not only on the technical aspects, but more on their impact. Specifically, these two papers change the way we look at privacy and how our actions reveal important information about us which was not obvious in the first place. ...

Via Catalana from the Twittersphere

Joint work by Manuel García-Herranz, Department of Computer Science, Universidad Autonóma de Madrid Manuel Cebrián, National Information and Communications Technology Australia, University of Melbourne Esteban Moro, Department of Mathematics, Universidad Carlos III de Madrid While public demonstrations are Social Science’s most important and studied phenomena, they are also the most mysterious and poorly understood ones. Demonstrations trigger new social movements, change countries attitudes, and have the potential to overthrow governments. ...

Are you a social keeper or a social explorer?

In our last (just accepted) paper “Limited communication capacity unveils strategies for human interaction” [link] we have found that we humans have different social strategies when we communicate/interact with people. Specifically, the sociability of a person (the total number of contacts in a time interval) which is usually taken as the connectivity in the social network is actually the result of two different human features: Social capacity: the number of relationships humans can maintain opened and which is limited Social activity: the number of relationships human form and destroy as a consequence of their daily tasks, family, events, etc. ...
