It's amazing what you can find and/or learn when you're surfing the web on a whim rather than as a means to an end.
Sandra's mention of Twittersheep today in Digital History got me thinking about Wordle, a similar tool that I discovered a few months ago. Like other word/tag cloud generators, Wordle takes any given text (from a website, a blog or a list you input) and uses it to create a colourful and attractive visual design. The program uses font sizes and colour to show you those words that are used most frequently in the text. Once the inital generation of the image has been done, most programs will allow the user to tweak colour schemes, add or delete words, fiddle with the layout (presenting the words vertically, horizontally, both, or placed randomly), etc. Pretty neat idea, right?
Wanting an excuse to play with this technology, I decided to use the labels that I had attached to my blog entries so that I could see what a more visual representation of The Perpetual Student looked like (the image at the top of this blog is the result). It's amazing to be able to see at a glance the breadth of topics that I've been inspired to blog about as a result of class discussions, course readings, newspaper and magazine articles, etc. It's immediately apparent that my studies this year are concerned with public history, digital history and museums. It's also pretty obvious that I'm a student at UWO and that I have a personal interest in human rights issues and the Holocaust.
I'm curious; what would a similar Wordle look like in another month? Six months? A year? Would it show the same trends or new ones? Would it be an accurate visual representation of my Public History interests, or might it reflect a conscious effort on my part to include new topics in order to diversify my posts?
I also found myself wondering about other ways data clouds could be used. I remember reading a blog post when I first discovered Wordle that suggested that data clouds might be used to visually display the slant that newspapers take on particular topics. For instance, by taking an article from the Globe and Mail and and using Wordle to compare it to coverage of the same event in The Toronto Star, one might be able to visually discern the journalist's or newspaper's bias depending on the words that are given more or less emphasis. Or maybe the image could be used to determine the focus within an event - is it on the people involved? The politics? The geography? Wikipedia also provides an example of a word cloud that used information that might traditionally have been expressed in graph form (in this case population data) and re-imagined it as a cloud, with population densities attached to specific colours within the cluster. And I can easily imagine a student using it to determine the topics a professor has emphasized in their lecture notes (and therefore the material to study for the exam) or a secondary school teacher using it to show the themes of a novel. I suppose the options are endless for a person willing to use a little imagination.
But Wordle is not all moonbeams and roses. Due to their use of Java Script, you aren't able to save your Wordle image to your computer using the obvious cut and paste options. You have to jump through the hoops of using the "Prt Scrn" option, pasting it into a Paint document and editing it from there. (Conveniently, though, you can choose to save your Wordle image to their database and share it with the online community hassle-free)
In my case, however, the print screen option on my computer wasn't playing nice and I was forced to troubleshoot (something that I always resent, and yet feel smug about when I eventually find a method that works). Anyway, I did what I always do, which is to Google it and came up with a handy About.com entry that led me to a new and fascinating discovery - the Vista Snipping Tool. I had no idea I even had a feature like that on my computer. And from the Snipping Tool I was given the option of saving my file as a GIF, a PNG or a JPEG. I had no idea what these acronyms even meant, so I was then forced to go look that up and figure out which would be most useful for my situation.
It was like tumbling down the rabbit hole. What should have been a quick and playful experience turned into hours of playing, troubleshooting, contemplating and blogging. Before I knew it, all those wonderful intensions I had of doing my Museology readings tonight had slipped away. But, as the saying goes, "The More You Know."
