dbpedia

I have the SPARQL DBpedia Query below: PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX foaf: <http://xmlns.com/foaf/0.1/> PREFIX vrank:<http://purl.org/voc/vrank#> PREFIX dbpedia-owl: <http://dbpedia.org/ontology/> SELECT distinct ?Nom ?resource ?url (count( (?o) as ?nb)) WHERE{ ?resource rdfs:label ?Nom. ?resource foaf:isPrimaryTopicOf ?url. ?resource dbpedia-owl:wikiPageWikiLink ?o ?Nom <bif:contains> "Apple". FILTER ( langMatches( lang(?Nom), "EN" )). MINUS {?resource dbo:wikiPageRedirects|dbo:wikiPageDisambiguates ?dis} } Group By ?Nom ?resource ?url I want to get the number of

What are http://dbpedia.org/snorql/ and http://dbpedia.org/sparql/ and http://querybuilder.dbpedia.org/ ? Both SnorQL VS SparQL seems to run the following code similarly : SELECT ?resource ?value WHERE { ?resource a <http://dbpedia.org/class/yago/CitiesAndTownsInDenmark> . ?resource <http://dbpedia.org/property/populationTotal> ?value . FILTER (?value > 100000) } ORDER BY ?resource ?value They are (different) user interfaces that let you build and execute SPARQL queries on the DBpedia SPARQL endpoint http://dbpedia.org/sparql/ . The results should be the same in all three environments, because

I am sure what I want to do is very easy, yet I cannot seem to get the query right. I have records in dataset which have values such as city name e.g. 'New York' and it's corresponding country code e.g 'US'. I also have access to the full country name and country ISO codes. I would like to get the population and abstract value's for these cities off dbpedia, by using a where clause such as: Get population where name = "New York" and isoCountryCode = "US" I've searched for help on this to no avail. so far I have been kindly helped by @rohk with this query, which does not fully work for all

When I execute the following query on http://dbpedia.org/sparql using (dotnetRDF) VDS.RDF.Query.SparqlRemoteEndpoint.QueryWithResultSet() everything works fine. SELECT ?film ?p ?o WHERE { ?film <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Japanese_films> . ?film ?p ?o } limit 500 But when I try this query using SparqlRemoteEndpoint.QueryWithResultGraph() CONSTRUCT { ?film ?p ?o} WHERE { ?film <http://purl.org/dc/terms/subject> <http://dbpedia.org/resource/Category:Japanese_films> . ?film ?p ?o } limit 500 I've got RdfParseException with message "[Line 456 Column 29]

Closed . This question needs to be more focused . It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post . Closed 4 months ago . I need to import dbpedia into neo4j. I download the dbpedia from here: http://wiki.dbpedia.org/Downloads37 Any idea? I am currently doing the same thing. I found that the biggest problem for this is the indexing so the best solution is to write a java program that extracts the statements with md5 hashes into a triple file like follows: subjectHash \t predicateHash \t objectHash

I am trying to run this query on http://dbpedia.org/sparql but I get an error that my query is too expensive. When I run the query trough http://dbpedia.org/snorql/ I get: The estimated execution time 25012730 (sec) exceeds the limit of 1500 (sec) ... When running the query through my python script using SPARQLWrapper I simply get an HTTP 500. I figure I need to do something to optimize my SPARQL query. I need the data for iterating over educational institutions and importing it in to a local database, maybe I am using SPARQL wrong and should do this in a fundamentally different way. Hope
