Data Mining the US Senate Votes

AJ writes "We used some old and new data mining techniques to see what was happening in the US Senate in 2003. Among other things, we identified the 'social' network of similarities between senators, how influential is each senator and each state, and a 3D VRML view of the Senate. You will be able to check whether Senator Kerry was a centrist or a liberal, and who is acting more cohesively, the Democrats or the Republicans. We provide our data and the source of all our analysis software (Orange and MPCA, both under GPL)."
