OpenCyc for the Semantic Web
OpenCyc has just been released under the creative commons license.
Now it is even easier to use the rich and diverse collection of real-world concepts in OpenCyc to bring meaning to your semantic web applications! The full OpenCyc content is now available both as downloadable OWL ontologies as well as via semantic web endpoints (i.e., permanent URIs). These URIs return RDF representations of each Cyc concept as well as a human-readable version when accessed via a Web Browser.
Truly impressive, from what I’ve recently learned about this project it represents decades of work and now it’s available for everyone to share for free. Kudos Cycorp! I believe this is an extremely valuable gift to mankind. Here’s a quote from Z-Blog; “OpenCyc is probably currently bast available and open ontology of the world.”
I think it will be interesting to see what people build with this and other massive linked open data stores. The first thing that comes to mind for me is how this fairly rigorously disciplined ontology, which was built by very serious professionals over a long time might be combined with the more informal but dynamically evolving ontologies of similar scale. For example something like as DBpedia. DBpedia reflects the informally developed, but possibly equally massive knowledge base harvested from Wikipedia.
One thing I learned while developing an internal corporate semantic wiki, was that the mix of informal and formal/dicisplined ontology development was of value almost from the start. perhaps we’ll get to see someone repeat the same idea with these massive kowlege stores on a much bigger scale. I can only guess that the folks at Freebase and other similar projects are already hard at work doing just that.
