I used that during my BSc. Thesis, the non-free version includes data that is of higher precision and more useful for the military use. Which they have been building this for. It was used to answer questions regarding current threats and find out which other threats nobody has thought about could also occur, where, by whom etc. You can research that, if you want. But one thing is true, the information on them is scarce. I think they have had held a talk at Google though, if I remember correctly.

Tl;Dr.: Cyc is military precise, OpenCyc is not. Use case: Terror-Cell and threat identification, Information Gathering, Reconnaissance, Data-Fusion

It never made sense to me that the whole process would be manual. I would've developed an AI that could use their "complicated and cumbersome" forms automatically based on "Speech or Written" Input

There is also: http://www.larkc.eu/ and many other alternatives "Expert Systems". I heard the the military version of http://clipsrules.sourceforge.net/ is pretty good and in use here and there. But I don't know of the current progress and use of such systems. Can someone involved or knowledgeable give us an update on the state-of-art in AI/Expert-Systems used by the mliitary? I like to stalk military technology based developments =)

A modified version of the Cyc inference engine was used in the initial development of LarKC[1].
