topical_concepts should use foaf:focus not skos:subject
topical_concepts gives the topical page for each category, eg
dbp:Category:Programming_languages skos:subject dbp:Programming_language
But there's no such property. I suggest to use foaf:focus "The underlying or 'focal' entity associated with some SKOS-described concept".
The same prop is used by Getty TGN, VIAF, FR BnF, UK BL.
However, now the data is gone from dbpedia.org: this query returns only a few thousand. select * {?x skos:subject ?y} But the dataset http://data.dws.informatik.uni-mannheim.de/dbpedia/2014/en/topical_concepts_en.ttl.bz2 has a lot more lines.
This one finds no topical link: select * {dbcat:Programming_languages ?p dbr:Programming_language }
And could someone explain where this skos:related came from? dbr:Category:Programming_languages skos:related dbr:Category:Programming_language_topics
IMHO the topical links are quite important for some classification tasks. E.g. WiBitaxonomy could use them strongly to tie up the page vs category hierarchy.
- topical_concepts should have a link on the Download2014 page
- skos:related is #387
- "skos subject" appears in several source files, including in non-semanitc (bogus) URLs like "http://www.w3.org/TR/skos-reference/skos.html#subject". So it should be checked carefully and all instances eliminated
Any progress?
