Doug,

 

You are absolutely right pointing to Cyc.

Here is the quote (based on the work Cyc did for Clevelend Clinic) I received a couple days ago in response to my question.

 

“A quasi-quantifiable example comes from looking at queries done for the Cleveland Clinic (for cohort formation for clinical trials).  If one looks at the concepts/assertions touched in order to answer their queries -- most of which focused on finding patients or procedures that met some criteria, rather than abstract questions -- something in excess of 90% of the concepts touched to find the answer were ones that were not added as part of the domain knowledge for that application but were more general background concepts and facts.”

 

So far, I did not find any study that can better quantify the values, my personal rough estimate for “tribal knowledge” is about 80% and captured knowledge is 20% in a corporate information environment.

 

I highly appreciate any information on the subject.

 

Thank you,

 

Yefim (Jeff) Zhuk

I don't know about the statistics, but the issue of expressing the
normally unstated knowledge constantly appears in ontological engineering.

Encoding such "common sense" knowledge, which is assumed but not stated,
was a major part of Doug Lenat's original dream for Cyc.  He wanted to
encode enough information to cover the unstated parts of any encyclopaedia
article.  His idea was that by encoding merely the assertions in the
article, the information in Cyc would be sufficient background so that
any question about the material could be answered by the system the
same way a person who didn't know the subject could after reading the
article.
