Link ontologies from DBpedia to external ones with sameAS

Is there a way in SPARQL to automatically connect instances of one ontology in DBpedia and another in a different database. For example

http://yago-knowledge.org/resource/Daphne_Gere and http://dbpedia.org/page/Daphne_Gere

are similar and connect with the propriety sameAs, but I would like to be able to do it for all instances of the ontologies where they belong

http://yago-knowledge.org/resource/wordnet_actor_109765278 and http://dbpedia.org/ontology/Actor

So for example the result will be a table that has all the instances from one class with their equivalent in the other class.

Solution

  • How about a simple query to DBpedia, which already contains (most of?) the links that you want?

    select ?dbid ?yagoid where {
  ?dbid a dbpedia-owl:Actor ;
        owl:sameAs ?yagoid .
  filter strstarts( str(?yagoid), 'http://yago-knowledge.org/resource/' )
}
limit 100

    SPARQL results

    dbid                                       yagoid
