Hi,
I do have a strange behaviour that I don't understand, working with OWLIM 4.3.
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
