Hi,
I'm not if this is the correct forum to ask but hope you can help. This query takes over 20 seconds with jena:
SELECT DISTINCT ?s ?p ?o WHERE { GRAPH <http://www.lingsoft.fi/> { SELECT DISTINCT ?child WHERE { {<http://www.lingsoft.fi/c16e9937a515bda6> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/e56f6309f0d86b95> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/b393055ac0f3a0bc> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/642194686a67f935> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/a9beeb4bf0b0af70> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/ce3598292f301cec> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/26aa300e4c033981> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/bd07d765f36ea88f> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/bcf9e082e2ae8c9b> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/78d3955357a8ac10> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/369b1a9c822f55db> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/7098a84669b9feca> skos:narrower* ?child} UNION {<http://www.lingsoft.fi/b7cb30c4efed996a> skos:narrower* ?child} } } GRAPH <http://www.lingsoft.fi/resource-meta/> { ?s <http://purl.org/dc/terms/subject> ?child . ?s <http://purl.org/dc/terms/isPartOf> <http://www.lingsoft.fi/rdf/uid/574ef1a40236a> . ?s ?p ?o } }First graph query is for getting keywords from an ontology graph, second is for querying documents having those keywords. Is there better way/order to make this query? Thank you for the help, Mikael
