opencyc

Yep. And it may be just a subset, but it's pretty much the answer to "I wonder what is the closest thing to Cyc we have in the open source realm right now?". See: https://github.com/therohk/opencyc-kb https://github.com/bovlb/opencyc https://github.com/asanchez75/opencyc Outside of that, you have the entire world of Semantic Web projects, especially things like UMBEL[1], SUMO[2], YAMATO[3], and other "upper ontologies"[4] etc. [1]: https://en.wikipedia.org/wiki/UMBEL [2]: https://en.wikipedia.org/wiki/Suggested_Upper_Merged_Ontolog...

Has anyone investigated to see if OpenCyc can be converted to natural language (presumably English) and then injested into this? Cyc made an attempt years ago to "encode common sense" and a subset called OpenCyc was released. That might be a great way to kickstart information representation of the real world. The latest version of Cyc is proprietary but I think there OpenCyc is an open subset (though I'm having trouble confirming that, so the licensing may not be good).
