Drew, Frank --

Some thoughts about Drew's cross post, below....

Agreed, it's going to be very difficult to do anything useful in the real 
world with automatic mapping of one ontology to another.   And it requires 
a lot of skill to do it manually.

I'd argue that the skill requirements can be somewhat reduced in an 
approach using lightweight natural language attached to highly declarative 
rule processing.

There's a little example of this, called MergeOntologies1, that can be run 
by pointing Netescape 7 or Mozilla to www.reengineeringllc.com  .

Even in such a simple example, the reasoning is a bit complicated to 
follow.  So explanations -- in English -- are needed and are provided.

What do you think ?           Cheers,    -- Adrian

[Frank McCabe]
The 'problem' I was referring to was that of automatically mapping one
ontology (written I assume by person or persons A) to another (written
by persons B).
People have asserted that there exist automatic tools for doing that.
And I was pointing out some corner cases.
People are kidding themselves. Not to offend their fans, but the
results on automatic ontology mapping using probabilistic methods,
machine-learning techniques, graph isomorphism, word repetition,
etc. etc. are publishable and will make some of us into academic
stars, but they won't actually begin to solve the problem. The
problem is AI-complete. It's like Richard Waldinger's solution to the
automatic-programming problem: A. Create an intelligent robot.
B. Give it a Lisp manual to read.
