A real semantic network analysis of Obama’s inaugural speech

I’ve been watching inaugural events all day, and noted the numerous Wordle examinations of the inaugural. Here’s an example of a true semantic network analysis of the inaugural via leximancer, a semantic network analysis software that doesn’t look as cool or as pretty as Wordle, but provides a more quantitative analysis. Leximancer weights the concepts based on their association with various words and provides a map of how the concepts are related (brighter circles equal greater emphasis, for instance).
Some short explanation: the circles represent concepts, the lines represent associations between concepts. The only reason I know about this is because of my dissertation.
