extracting brand names from dbpedia

Question

i'm trying to find as much as brands i could find from dbpedia

i tried searching of entities of those types :

http://dbpedia.org/resource/Public_company
http://dbpedia.org/resource/Aktiengesellschaft
http://dbpedia.org/ontology/Company

is there some other properties for significant brands like : Nike , Adidas , Levi's , Macdonald's , Pizza hut

what the best practice methodology that i could follow in identifying properties for any type ?

Accepted Answer

One big issue is the heterogeneity of dbpedia data. Not every "thing", which should be "rdf:type" "dbpedia:Company" has this predicate. You must work around this and combine several queries using UNION.

Try adding triples like those to the query to increase the selectivity:

          { ?company ?p dbpedia:Corporation . }
           UNION
          { ?company dbpedia:industry ?industry . }
           ...

You should also look into skos:narrower with respect to dbpedia:Organization. Finally, try to find predicates that support your intention with a query like this:

SELECT DISTINCT ?b COUNT(?b) as ?count WHERE {
         ?e dbpprop:companyType ?b
    }
    ORDER BY DESC(?count)

So I reckon, you should go "spelunking" for supportive triples, that will yield additional "brands". You won't write a query that extracts actually all "brands" in dbpedia.

Besides "brand" is a little vague. You should probably elaborate, on what exactly you want to accomplish.
