I assume you are referring to the international DBpedia, i.e.
http://dbpedia.org
An intuitive approach is to run this query [1] over the SPARQL endpoint
[2], page through its results with OFFSET and LIMIT, and run a describe
query (e.g. [3]) on each of the results.

This mapping statistics page [4] may help you, it contains information
on the actual usage of the Wikipedia template mapped to Company [5].
Cheers!
