Get Place categories from DBpedia using SPARQL - categories

Question

The following code queries DBpedia for places within a bounded geographic area and returns the name, lat, and long of the place. I'd also like the query to return the category of the place--e.g., park, restaurant, museum, etc.
The following code works fine.
sparql = SPARQLWrapper("http://dbpedia.org/sparql")
sparql.setQuery("""
PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#>
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX category: <http://dbpedia.org/resource/Category:>
SELECT * WHERE {
?s a dbo:Place .
?s geo:lat ?lat .
?s geo:long ?long .
I tried to add the following code to get categories for places, but this doesn't work:
?s category:cat ?cat .
What should I add/change? Thanks.

Answer 1

You can get the category of a place (assuming you mean the type) by finding the type (rdfs:type) or the subject (dcterms:subject) of a resource. In DBPedia the first relates to the DBPedia and Yago ontologies and the second is a SKOS hierarchy in DBPedia. Here is an example query:
PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#>
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX dcterms: <http://purl.org/dc/terms/>
SELECT * WHERE {
?s a dbo:Place .
?s geo:lat ?lat .
?s geo:long ?long .
?s a ?type .
?s dcterms:subject ?sub
}
Note that you will get multiple types and subjects for each place.
