OpenCyc is the open source version of the Cyc technology, the world's largest and most complete general knowledge base and commonsense reasoning engine. OpenCyc can be used as the basis for a wide variety of intelligent applications. This is release 1.0 of OpenCyc featuring the complete Cyc ontology of over 260,000 terms and their definitional assertions numbering over 1.8 million. OpenCyc requires about 500MB of disk space and performs best with over 512 MB RAM. One GB of RAM is recommended for Cyc when accessed by Java applications.

Yes, but that still means it's not really "open." At least, it doesn't fit the definition of what most readers of this site would associated with "open" and software.
Not that there's anything wrong with that! I'm a commercial software developer myself. I just think the other poster is right, and the name is a bit of a misnomer.

Well, it depends how you see it. If you see Cyc as a two-part project, then it's half open. But these two parts can be used individually and a new open source application can be created and takes full advantage of the knowledge base. If OpenCyc was supposed to be only the "data" part, then it is indeed open.
Anyways, this project is a monster (in a good way).

Well, I guess they want to be able to pay their bills too so they had to keep something proprietary too from the whole deal. They have spend many years researching Cyc.
