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 of a wide variety of intelligent applications such as:
- rapid development of an ontology in a vertical area
- email prioritizing, routing, summarization, and annotating
- expert systems
to name just a few.
I'm not sure about their claims, however, the project looks very interesting. I just got it up on a system and now my part is done. I hope the people who are suppose to use it enjoy it as well. buhahahaha.
