I have downloaded the Short Abstracts ttl file and I need to filter them by type "http://umbel.org/umbel/rc/Politician". I understand that the "Short Abstracts" dataset doesnt have the "type" data, and I'm somehow failing to locate the one that does. In other words, which dataset contains the wiki resource to "type" mapping?
There are multiple type datasets in every DBpedia release
e.g. in the DBpedia English dataset we have
Then, we also have external types in the links folder, e.g.
umbel_links_fixed.nt.bz2 (These are the ones you refer to I think)
Hovering over the download table of the latest release there are descriptions for each dataset.
