Deconstructing texts with a Woodchipper!

Woodchipper is a tool that apparently deconstructs texts, decomposes the text into relatively orthogonal concepts and then plots them together to look for commonality.  Has anybody else ever hear of this Woodchipper tool?  It has an alpha test going, but it seem that you need to be affiliated with an institution to sign up and I just wanted to play with it.



This author has decronstructed and compared several gothic texts using the tool.  The plot above has these tantilizingly interesting yet unlabelled axes.

Here the tool is described at the Maryland Institute for Technology in the Humanities (MITH)
