Hi Danny, >>Hello >> >>I'm looking for an algorithm to remove duplicate anonymous resources >>from an RDF-Model. >> >>Fo example, given the graph: >> >>(1) _:a rdfs:label "test". >>(2) _:a rdfs:comment "...". >>(3) _:b rdfs:label "test". >> >>The algorithm should tell me that I can safely drop statement 3. >> >> > >Ok, so presumably you can't know that _:a and _:b are the same node >without looking at other parts of the graph... > > If this is the whole graph, there is nothing which makes _:a and _:b different, as there is no interpretation in which the graph containing the first two triple has another truth-value than the graph with all three triples. >The nearest I've come to this is smushing on IFPs, recently with >Morten's Redland smusher [1] - there may be something useful around >his notes/code. > > IFP/FP-Smushing is not what I'm looking for, event though - for performance reasons - an rdf-entailment smusher should probably be ifp/fp aware an treat functionally grounded nodes similarly to "naturally grounded"-nodes (i.e. literals and named resources). cheers, retoReceived on Monday, 21 November 2005 10:43:47 UTC
