ECIG - presentation

I've presented "Digital Trends" to ECIG 2007. Very well received. Slides are available here

Several interesting questions and comments. One very respected participant expressed concern as to the validity of relying on the digital sphere as a proxy for public opinion.

1) Good point that must be investigated. As I indicated in my talk, my modest goal was to ascertain the apparent reliability of certain time series extracted from the digital sphere using the (non trivial) procedure developed by Swammer. Preliminary results are very encouraging. Next steps will explore validity issues (in simple terms, time series seem to track well. That doesn't mean that we know what they track)

2) Swammer shows here that web series are a good predictor of actual voting behavior at the time of the election.
