Dear Vladimir,
I'd second Martin's view from a very practical perspective.
You've probably seen dozens of databases containing statements such as artifact
A was created by agent B. If we assume that all of these statements imply the
existence of a creation event, then we have a clear migration path in cases
where additional information needs to find a suitable representation.
Another use case is integrating "low-res" and "high-res" knowledge bases, where
"low-res" statements have to be translated into a more complex representation even if no
information is added during the process.
Best regards,
Detlev

"rights held by").
Hi Martin!
In my opinion, a shortcut should never infer a long-path.
Hi Vladimir,
My question was about logic, and not about a knowledge base. We intend to
separate these two strictly.
In case a longpath can be inferred, it logically exists. If one or more of
the intermediate nodes can be inferred to exist, they are potentially
present in other information we are interested in integrating with it.
Then, we can find new links the shortpath did not provide.
That is the idea.
Best,
martin
- IMHO the purpose of a long-path is to provide additional info (e.g. a
date), but the shortcut cannot infer that
- the purpose of a shortcut is to allow simpler representation, so why
also infer a more complex but incomplete representation (no additional
details)?
- in cases when both shortcut and long-path are provided explicitly, an
inferred long-path would be superfluous (duplicate), or a system needs to
go through extra effort to somehow correlate the inferred to an existing
long-path
Cheers! Vladimir
