Recently, we reported about the Open Knowledge Graph project, an effort to crowd-source a Google Knowledge Graph API. The project seems to have taken off quickly, with over 2,500,000 triples collected as of this writing (and climbing quickly). We spotted this post on Google+:

The last line, about the “public non-service announcement” left us wondering…is the project under pressure to scale back or worse, to shut down? Is this work competitive with Google or does it hurt their business interests in some way? We have been watching, and haven’t seen any announcement yet, but the post certainly left us waiting for the distinct sound of a dropping shoe. Then we saw this follow-up, with ominous Latin:

OpenKnowledgeGraph - memento mori

Momento mori, for those not fluent in Latin (like yours truly), “is a Latin phrase translated as “Remember your mortality”, “Remember you must die” or “Remember you will die.”

Whatever the future of the OKG project holds, the original paper has been accepted for presentation at the “Knowledge Extraction and Consolidation from Social Media” workshop at ISWC2012, and with the exponential growth of this crowd-sourced project, it will be interesting to see what information and insight has been gleaned thus far.

Pending this “public non-service announcement,” now could be a good time to run some SPARQL queries on the data, in case this excellent resource does disappear.
