KCVC might be regarded as similar in spirit to Wikipedia, although the intended audience, artificial intelligence systems, differs.
Although the resulting knowledge is not formally represented, it is provided to researchers with parses and other meta-information intended to increase its utility.
Later, this group released ConceptNet, which embedded the knowledge contained in the OpenMind Common Sense database as a semantic network.

It automatically generates questions in English from an underlying predicate calculus representation of candidate assertions produced by automated reading of web pages, by reviewing information previously entered directly in logical form, and by analogy and abduction.
