Hello Everyone,
First off, I want to apologize in advance for any obvious questions I
may ask. I'm new to this list and new to dbpedia (and to rdf, sparql,
etc etc). I've been playing around with using the dbpedia data set to
extract date information about historical events.
The query that I'm running through snorql is:
SELECT ?x ?y WHERE {
?x dbpedia2:date ?y
FILTER regex(str(?x), "Battle")
}
LIMIT 50
This returns results quickly, but the vast majority of the date
information is: "–"@en
Looking through the source on wikipedia it seems that many dates are
structured like:
date=[[September 12]] – [[September 15]], [[1814]]
which creates hyperlinked date information. I'm guessing that the
dbpedia extraction algorithm ignores the hyperlinked data and just
pulls out the &ndash?
My question is: can this data be pulled out in any other way or
extracted in full the next time the dbpedia data set is updated?
