In this case it sounds like analyzing a corpus of actual
data is closer to Paola's needs. There's only so much of this notion
of similarity that you can ever expect to find in the machine readable

Although the coverage isn't all you might hope for, it might be worth
taking at look at the Web Data Commons extractions from the Common
Crawl dataset &

There should be more than enough in there to do some basic analysis of
which properties and types co-occur in the same pages, or when
describing the same entities.

The use case here though doesn't sound so much about RDF vocabulary
terms, more about natural language similarity measures in general
(e.g. the likes of ), which is a bit
beyond the scope of this list.
