Only a few days left until the start of Open Repositories 2010 (6 to 9-JUL-2010 in Madrid, Spain). The conference brings together developers, managers and stakeholders in the context of digital repositories across the world.

In anticipation of the conference, many have already begun to share information. Given the increased attention on analysing Twitter-feeds, I performed a co-occurrence analysis of Open Repository 2010 related hash-tags with the aid of Social Network Analysis. Based on this TwapperKeeper Stat, created by Adrian Stevenson, and parsing the hash-tags out of the 64 tweets, the network allocates 34 unique twitter users and 14 hash-tags (for more methodological background see my paper on the methodological status of co-authorship-networks).

The following visualisation with the help of both R and visone is based on a spring embedder, thus assigning forces between vertices alias nodes. The nodes furthermore reflect the bipartite arrangement as well as the degree, i.e. as bigger the nodes (and their labels) the more links they receive (in the case of the hash-tags) or pass out (in the case of the users).

At a glance, it is nice to explore, how the hash-tags are related to each other and how well-connected repository developers are. But just feel free to explore for yourself. It would be of interest of how the network will evolve.

See ya  in Madrid!
