empirical cloud
The discussion about updating the Linking Open Data cloud got me thinking it would be interesting to try to visualize the actual owl:sameAs links in the Billion Triple Challenge dataset [1]. It turned out to be relatively easy to get something somewhat workable with tools like zgrep, sort, uniq, a couple of custom scripts, and the handy ProtoVis library [2]. You can view the result at: http://inkdroid.org/empirical-cloud/ If you notice the links to the rdf/xml and Turtle you'll see I tried my hand at representing the underlying data using void, foaf and dcterms. There's definitely room for improvement, so if you are so inclined please tinker with it and send me a pull request on GitHub [3]. Thanks to Gunnar Grimnes and Dan Brickley for ideas and help. //Ed [1] http://challenge.semanticweb.org/ [2] http://vis.stanford.edu/protovis/ [3] http://github.com/edsu/empirical-cloud
Re: empirical cloud
Really cool Would it be possible to know what each node is (hovering over the node). Or could you tell us what are the 4-5 main nodes. I'm guessing DBpedia... Is Foaf one of the main nodes?

Re: empirical cloud
It *does* do this; are you using e.g. Chrome? It takes a few seconds.
