Social Networks - GeoCom 2011

I am at GeoCom 2011 today. It takes place at UCL here in London from today (20 - 22 of July). The conference focuses on geo computation with focus on complexity and modeling. The keynote today was given by Professor Peter Nijkamp from Vrije Universiteit, Netherlands as 'Digital environments and ‘real world’ geographies'. THe detailed program can be found HERE.

I will be presenting a poster on social networks based on Twitter data. The plot is using the data that was collected for the London NCL map during the period of one week. A detailed, interactive version of the graph can be fond as published in an earlier post.

London NCL Social Network

Graph by urbanTick using the GMap Image Cutter / London NCL Socia Network - Use the Google Maps style zoom function in the top left corner to zoom into the map and explore it in detail. Click HERE for a full screen view.

The network is based on activity on the Twitter platform. The graph shows connections based on @ tweets and RT tweets. The actual followers or friends are not taken into account. The activity is what can be read from the tweet content. So far we have not been looking into the tweet content beyond this networking information, but it could be an upcoming step.

Interesting is to see how information is passed on from users in RT's. It will be possible to analyse the spreading of information spatially and how this travels the urban area as for example London in this case.
