Changelog

2011 October 3

Concept normalization now depends on WordNet, which we access through NLTK.

If you don't yet have NLTK, download it from http://nltk.googlecode.com/files/nltk-2.0.1rc1.zip. Unzip it and run python setup.py install. (Put sudo before that if you're installing into a global Python environment on Unix.)

• Changed URIs so they can contain arbitrarily nested lists.

2011 September 30

• Added sources and conjunctions as new node types.
• Added the "normalized" relation, which points from an assertion (or concept) to a simplified/normalized version of it.
• Began importing data from the pet game.
