I’ve been looking at the OpenCyc Foundation’s Concept Browser page. I searched for the concept “product”. It took me to a helpful page that says:
Each instance of
thing that exists in time
that is, or was at one time, offered for sale or performed as a commercial service, or was produced with the intent of being offered for sale. Positive examples of
- a barrel of crude oil being shipped to a customer;
- a completely assembled automobile in a factory;
So far so good.
Then, under the section called “Examples of Sales product”, they have a number of “Ballistic missile” entries. They all point to different entities. Obviously no disambiguation has been done. The same with “Cruise Missile“, Iranian phantom fighter planes, etc. Has the arms sales market picked up so much? :-)
Seeing biological weapons scared me though. I didn’t even know that there was an “Y2 Stage 4 Anthrax Sprayer” in existence. Scary!
Obviously these are not manually entered entries but the result of some automated inferencing process going wrong or some information extraction algorithm not doing the right thing.
