Wordling Through Public Opinion

I've been examining audience interpretations of movies, TV shows, and web video for a few years now. Recently, a friend turned me on to this Wordle application which makes word clouds of any block of text you give it. Word clouds got a lot of press recently when CNN used it to analyze one of Obama's speeches (sadly, people didn't "get" what word clouds can tell them). Anyway, like any good data visualization tool, it allows you to see, at a glance, some of the trends in your data. There are, of course, limitations (as will become apparent in the examples i give below), but it could be an exciting new way to look at public opinion quickly. Take blog posts or comments from thousands of different people, feed it into Wordle, and you'll get a general idea of what that portion of the public is thinking about (or what they think about a certain issue).

Here are the results of my wordle of people's evaluation of several movies on IMDB. I drew the comments from the headings of the first 300 posts for each movie. Check 'em out.
Shawshank Redemption (the highest rated film on IMDB). No big surprises. People think its the best. Its interesting to note that they think its the best ever. If you look closer, you can see adjectives like "brilliant" and "moving." These may not seem surprising, but when you start comparing the different word clouds to each other, even the films that everyone loved, you start to see that fans put emphases on certain elements of certain films.
Amelie (44 on the list of top 250 IMDB). Interesting to see the word "overrated" in there. People define this movie by the fact that its French, and they find it charming.
Love Guru (I had to pick a bad one for contrast). This represents the limits of assuming that word choice (taken out of context) will tell you what people think. The word "funny" might have been part of the phrase "not funny," but Wordle can't tell you that. Its interesting to see that "bad" is used far more than "worst," and that people think of this as a Mike Myers film more than anything (again, obvious, but worth noting). Also, the word "critics" indicates that the critics lambasting of this film carried some weight with people (you don't see "critics" in many other worldes for other films).Casablanca (11 on Top 250 list). Again, "best" and "greatest" are there. "Classic" is there. It would be interesting to see at what year the word "classic" becomes commonly used by people. You would expect it to grow in highly-rated movie word clouds the older the movie is, but maybe there are certain characteristics that make people call a movie "classic" (the centrality of a romance? PG content?). In any case, its far more interesting to me to look at the ways in which hundreds or thousands of viewers use words like "classic" than the ways in which a handful of critics use them. Definately something worth exploring further.
