Hello, when I query in Fuseki like this: PREFIX : <http://dsc.nlp-bigdatalab.org:8086/>
SELECT * WHERE { ?s ?p ?o. } #query1 It can return the many results ,one of the results is: :口腔毛滴虫病 rdf:type :症状 when I query like this: PREFIX : <http://dsc.nlp-bigdatalab.org:8086/> SELECT * WHERE { :口腔毛滴虫病 rdf:type ?o. } #query2 it can return the results: :症状 but when I query like this: PREFIX : <http://dsc.nlp-bigdatalab.org:8086/> SELECT * WHERE { ?s rdf:type :症状. } #query3 it returns: No data available in table it confused me again is this the problem related to the OWL data in ..\jena\apache-jena-fuseki-3.5.0\run\databases? or RDF data in ..\jena\tdb look forward and thanks for your reply
