Visual Analysis of Obama's Acceptance Speech

Using Wordle, I've created a visual analysis (comparable to a tag cloud) of Barack Obama's acceptance speech. Wordle is a simple tool that allows us to use visual cues to illustrate word frequency. In this case, words that are "gray" and "small" appear less frequently than words that are "bright" and large.
This is not a "straight" visualization of the text of the speech. Instead, I have eliminated words that appeared fewer than four times. In addition, I normalized some words. Wordle automatically eliminates common words like "a" or "the." My methodology follows:
Normalization
- American - Americans - America - america's ... became America
- created - create ... became create
- family - families... became families
- investment - invest ... became invest
- job - job ... became jobs
- political - politics .. became politics
- safely - safe ... became safe
- United States became UnitedStates
- watching - watched - watch ... became watch
- woman - women ... became women
Words Removed:
These words appeared no more than three times in the speech:
across ... Afghanistan ... ago ... ahead ... alive ... also ... benefits ... best ... Bill ... challenges ... children ... college ... clear ... could've ... . cut ... else ... decades ... defeat ... deserve ... different ... energy ... failure ... finally .. finish ... first ... follow ... generation ... get ... hands ... hear ... heard ... hope ... idea ... kennedy ... lead ... less ... listen ... long ... makes ... military ... moments ... moral ... never ... old ... part ... poverty ... power ... proud ... pursue ... ready ... renewable ... require ... restore ... rise ... something ... still ... stop ... talk ... talking ... things ... troops ... . understand ... walk ... well
I see now that I should go back and combine a few of these words.
However, I also created a Wordle visual with full text of the speech. This image, with the dominant complementary words "America" and "American" illustrate the need for normalization.
More analysis on Friday. Time for bed!
Postscript: Wordle does not like my version of Firefox but plays nicely with Safari. Here is the modified Wordle image; here is the unmodified image.
