I looked at OpenCyc previously while investigating semantic networks, but not long enough to figure out how to do things with it. I'd be interested in hearing about what any of you have used it for. A map of English knowledge and relations between concepts ought to be pretty useful for some things.
I just tried to see if there was something I could do easily with it that would be cool to learn about. Still have not successfully started up the engine without closing all other processes to free up memory.
I was running it on a 4GB MacBook Air and I shut down other memory hogging programs like IntelliJ - then everything worked fine. I recently rented a 32 GB server for running a large RDF data store, and that is where I am trying to relearn OpenCyc (I spent a lot of time with version 1, but became interested in other things - I am going to give version 4 another chance).
I wrote that blog article. I would appreciate any feedback on the utility of loading the RDF data into an OWL supporting RDF data store (I have an Enterprise Stardog license, which is what I would use) or use OpenCyc as a service.
Years ago, the OpenCyc usenet groups were useful so I need to check there.
