Hello Barry, No, ?text is not bound to a literal, it is an instance of one of my classes (nlp:Text). As in my little testcase there is no ambiguity about that (nlp:hasLookupURI always has an instance of nlp:Text as object), I don't specify it in the query. Thanks Fabian

I think there is no need to provide detailed information about the dataset to understand my problem, but will give more information if needed. I have some texts with lookups on wordnet. With a query, I want to find the texts which have a look-up that is 'linkedTo' a precise wordsense. The linkedTo property being created by my self in the store. If I execute 2 queries about two different wordsense, the results are correct: I get the same text as the answer But if I merge the two wordsenses in a single query: the resultset is empty, and I can't understand why. Query 1: the following query returns one result: SELECT distinct ?text WHERE { ?ann1 nlp:hasLookupURI ?ws1. ?ws1 wn20schema:linkedTo{1, 2} wn30:wordsense-prey-noun-2. ?ann1 nlp:isAnnAboutText ?text. } Query 2: this other query returns the same result as query 1 SELECT distinct ?text WHERE { ?ann2 nlp:hasLookupURI ?ws2. ?ws2 wn20schema:linkedTo{1, 2} wn30:wordsense-snake-noun-1. ?ann2 nlp:isAnnAboutText ?text. } Query 3: now merging the two patterns should give me the same common result, but the resultset is empty: SELECT distinct ?text WHERE { ?ann1 nlp:hasLookupURI ?ws1. ?ws1 wn20schema:linkedTo{1, 2} wn30:wordsense-prey-noun-2. ?ann1 nlp:isAnnAboutText ?text. ?ann2 nlp:hasLookupURI ?ws2. ?ws2 wn20schema:linkedTo{1, 2} wn30:wordsense-snake-noun-1. ?ann2 nlp:isAnnAboutText ?text. } Thank you for any help Fabian _______________________________________________ Owlim-discussion mailing [email protected]http://ontomail.semdata.org/cgi-bin/mailman/listinfo/owlim-discussion
