Visuwords takes Princeton’s WordNet (see previous post), the data it is based on, one step further and turns into into a visually attractive “online graphical dictionary” that lets you “Look up words to find their meanings and associations with other words and concepts. Produce diagrams reminiscent of a neural net. Learn how words associate.”
I’ve got to admit, while WordNet itself might be fun for serious linguists to play with, this is fun for everyone, and far more accessible. I love how the nodes keep popping out. Give it a try at http://www.visuwords.com. The word “help,” for example, produces a particularly rich network.
