… political speech has often been subject to analysis but this here is a nice discovery of an interesting application for tag clouds to visualize repetitive frequency (via infosthetics)

Political rhetoric is one of the most interesting to analyse, because of the emophasis on using metaphors to convey various meanings within a speech. Our project tries to break down the rhetoric, take the words out of context, and treat them at face value in order to analyse the breakdown of content in these
speeches. Each group of metaphors is colour coded, and sized based on the number of frequency. This is generated using marked up XHTML that is put through a PHP script.
