There’s a very interesting site, run by a couple of Australian lads, called Text is Beautiful that provides some free tools that allow you to visually represent the relationships within a text. No this isn’t the same as Wordle, these guys have gone beyond that to develop what they call a Concept cloud, colours in the Concept Cloud are indicative of distinct themes and themes themselves represent rough groupings of related concepts. What’s a concept? Well a concept is made up of several words, with each concept having it’s own unique thesaurus that is statistically derived from the text.
So without further ado I took the Fundamentals of System Safety course that I teach and dropped it in the hopper, the results as you might guess are above. Very neat to look at and it also gives an interesting insight into how the concepts that the course teaches interrelate. Enjoy. 🙂
