Hello everyone,
I am a bibliometrics PhD and I am a newbie to dbpedia. I have been trying to
get region info through
Wiki infoboxes. I wrote the query as below:
SELECT DISTINCT *
WHERE {
?city rdf:type dbpedia-owl:PopulatedPlace .
?city rdfs:label ?label.
?city dbpedia-owl:abstract ?abstract .
?city dbpedia-owl:country ?country .
?country dbpprop:commonName ?country_name.
OPTIONAL { ?city dbpedia-owl:isPartOf ?partOf } .
OPTIONAL { ?partOf dbpprop:name ?partOfname } .
OPTIONAL { ?city dbpprop:region ?region }.
OPTIONAL { ?city dbpedia-owl:postalCode ?postal_code }.
FILTER ( lang(?abstract) = 'en' && lang(?label) = 'en' && regex(?country,
"Germany") && regex(?label, "Bonn"))
I realized that there is no region information for some places in their related
dbpedia pages even though the region info
appears in the original Wikipedia page. For example, for Bonn of Germany
http://en.wikipedia.org/wiki/Bonn
contains state info (North Rhine-Westphalia). However, in its dbpedia page
http://dbpedia.org/page/Bonn
I could not find this information. The same issue is valid for Leuven, Belgium.
Actually, the region information appears only
in the abstract part.
Am I missing something?
If you can guide me, it would be great.
Thanks in advance.
Kindest regards,
Mehmet
