metaphors in political speeches

as I mentioned previously, I've been spending a lot of time recently working on metaViz, a computational system designed to identify conceptual metaphors in political blogs. metaViz also includes analysis of the campaign speeches from McCain and Obama (presidential candidates from the two major political parties). there's a UCI press release that gives an example interpretation of some of the results. I think the major value of the press release is that it shows how the system is meant to be used and how one might go about interpreting the metaphors that it identifies. check it out, and let me know what you think.
