Hi all,
Wikipedia URIs evolve over time as new concepts are added and
disambiguated. Any data linked to those URIs would need remapping.
There is also a notability requirement for existence.
UMBEL has a nice subject concept space, though some would argue it is
just one view of the world. Linked entities can benefit if they find
a place in that ontology.
Exactly. One thing I will stress again in this discussion: UMBEL is
basically two things: (1) a Subject Concept structure (space) and (2) a
aggregation of Named Entities dictionaries (instances of classes).
Please refer to the glossary to read the definition of each concept[1].
DBpedia is about instances of classes. DBpedia is linked (via sameAs
since they come from the same data source: Wikipedia) to UMBEL named
entities, and not UMBEL's subject concept structure (the SC structure
helps instantiating these named entitites though).
So, two things here: Wikipedia articles can be referred to many things.
Two of these things are: this article is about this subject concept and
this article is related to this other named entity.
I think Jason is more thinking about linking Wikipedia articles with
topical concepts; which refers to UMBEL subject concept. The linkage can
be done using the umbel:isAbout predicate and any UMBEL subject concept.
