Entity missing entity_type attribute value

[marty]

Hi there,

I just noticed an entity being returned by "suggest" that has a
Freebase, a Wikipedia and a DBPedia link associated with it, yet no
"entity_type" (example below). Looking at the DBPedia URL, I can see a
lot of very meaningful type definitions in there, so I would expect
the entity to have an easily extractable entity_type.

Is this a bug or just something I'm missing?

Thanks,
Martin

Yes, we recommend resolving urls and getting your entity types directly
from 'the source' (dbpedia or Freebase).

We've implemented a limited set of entity types which we provide
directly in the API since there was very direct demand for them by some
users.

If you need 'the whole story', by all means just dereference the url! :)

I see. Well, to be honest I'm not asking for "the whole story" - in
the example shown above, the system doesn't even return a single type
where there are clearly many available. I guess my confusion is what's
the point in returning the entity_type attribute at all if it's
sometimes extracted and sometimes not..

Agreed,
there are two things at play:
- we only support a small subset of all types available in those two
databases, if it's not one of those types, we ignore it
- when the types are right we try to extract them, but that's not always
done properly and we continuously try to improve on that.
