For example, when merging four different datasets, you can use the following query on DBpedia to select everything about Sofia:
sparql SELECT * { { <http://dbpedia.org/resource/Sofia> ?p ?o . } UNION { <http://data.nytimes.com/nytimes:N82091399958465550531> ?p ?o . } UNION { <http://sws.geonames.org/727011/> ?p ?o . } UNION { <http://rdf.freebase.com/ns/m/0ftjx> ?p ?o . } }sparql SELECT * { ?s ?p ?o FILTER (?s IN ( <http://dbpedia.org/resource/Sofia>, <http://data.nytimes.com/nytimes:N82091399958465550531>, <http://sws.geonames.org/727011/>, <http://rdf.freebase.com/ns/m/0ftjx>)) }
