OUseful.Info, the blog…

A brief next step on from Preliminary Thoughts on Visualising the OpenEd09 Twitter Network and A Quick Peek at the IWMW2009 Twitter Network with a couple of graphs that look at the hashtag network around the JISCRI event that’s going on this week.

The sample was a taken from a search of recent #jiscri hashtagged tweets captured last night using the Hashtag Twitterers pipe.

The first chart was to look at people who the hashtag twitterers were following in large numbers who weren’t using the hashtag (I think…my experimental protocol was a bit ropey last night… oops).

The graphs were plotted using Graphviz – firstly a radial plot:

And then a circular one:

The circular one is quite fun, I think? :-) At a glance, it shows who the “external gurus” are, as well as the differences in their influence.

The second thing I looked at was the network graph of the JISCRI hashtaggers, showing who friended whom:

Here’s the circular view:

For a large event, I think this sort of graph could be quite fun to generate at both the start of the event and at the end of the event, to show how connections can be formed during an event.

For conferences that publish lists of attendees, popping up a poster of the delegates’ twitter network might provide an interesting discussion thing for people to chat around.
