Query works in Protege, not in Jena code
Hello, This query works fine and get data i-e Questions, answers, choices
and their score. But when I want to include object property hasComplexity
(its values are 1,2,3,4,5) and try to order it, its not working. (The query
still get data but not in order).
While this works inside Protege and show questions in order:
SELECT *
WHERE { ?questions dd:hasCategory dd:CatPhysics ; dd:hasLevel dd:levEasy ;
dd:hasComplexity ?y} order by ?y
//This query is in Jena code: I copy here it in Jena syntax
"SELECT * " +
" WHERE { "
+ "?Qs mo:Question ?QsDesc. "
+ "?QS mo:hasAnswers ?AnsQ. "
+ "?AnsQ mo:hasQuestion ?Qs. "
+ "?AnsQ mo:ChoiceOne ?ANSONE."
+ "?AnsQ mo:ChoiceTwo ?ANSWTWO."
+ "?AnsQ mo:ChoiceThree ?ANSWTHREE."
+ "?AnsQ mo:CorrChoice ?ANSCORR. "
+ "?Qs mo:hasCategory ?Cat. "
+ "?Cat mo:category ?CatName. "
+ "?Qs mo:hasLevel ?lev. "
+ "?lev mo:level ?LevName. "
+ "?Qs mo:hasScore ?point."
+ "?point mo:score ?Score. "
+ "?Qs mo:hasComplexity ?l. "
+ "FILTER ( ?CatName ='"+ctg+"' ). "
+ "FILTER ( ?LevName ='"+lvl+"' ). "
+ "}"
+ "ORDER BY (?l) "
+ "";
Re: Query works in Protege, not in Jena code
Posted by "Lorenz B." <bu...@informatik.uni-leipzig.de>.
1. Sample data means to have some instance data and not only a part of
the schema. Nobody here wants to generate instance data in order to test
the query locally.
2. And please use Turtle, RDF/XML is totally verbose.
As we already said, put the WHOLE data - that means the ontology
including the schema and instance data that you load with Jena -
somewhere online. Github is the most simple one.
And then show the sample code, that means the Java code snippet.
And show the sample output, i.e. the result you get back by Jena and
especially HOW you process the Resultset object.

Re: Query works in Protege, not in Jena code
Posted by Sidra shah <s....@gmail.com>.
Thank you Lorenz, you mean I copy the turtle of my ontology here? It will
be very large?
Actually what makes me confuse, when I run the same query in Protege(with
all Qs,Ans/Options), it works and order the questions.
In Jena, the order by part does not work.

Re: Query works in Protege, not in Jena code
Posted by "Lorenz B." <bu...@informatik.uni-leipzig.de>.
Sample data is not an abstract description of the data...it is proper
instance data, in best case in TURTLE syntax.
Sample code is still missing.
Sample output is not telling me that something does not work as expected...
"Not in the oder you want" is no real specification. The query will
order by the URIs of the complexity values. If not it's a bug.
But again, we need sample data, sample, code, which is also know as MWE.
And also the Jena version is interesting for the developers.

Lorenz, Each question has three categories (subjects), has level , and
recently I added hasComplexity which has values 1-5. I have added a
Complexity class and its members are 1-5 numbers. Domain is Question class
and range is Complexity class.
The query inside Jena works, load questions/answers/choices etc but not in
the order I want.

That doesn't answer my question. Can you try to compare the same queries
please?
Moreover what's missing:
1. sample code
2. sample data
3. sample output

The queries are different because in Protege I retrieve only questions and
their complexity number while in Jena I get questions, answers, choices,
scores and its complexity order.

Re: Query works in Protege, not in Jena code
Posted by Sidra shah <s....@gmail.com>.
Thank you Lorenz, 1,2,3,4,5 are resources and it has URIs. Question has
object property and value will be selected from one of the five values in
the owl file.

"object property hasComplexity (its values are 1,2,3,4,5)"
-> why do you say it's an object property if the values are numerical?
Moreover, you compare two different queries and then say one works in
Protege, the other not. That is a totally useless statement. It should
be clear that you should compare the SAME queries
It remains open what kind of RDF term the complexity values
are...literals or resources
