Hello everyone
I am a beginner with SPARQL and SPIN and am currently trying to build my
first ontology. I was able to figure out all problems with the help of
online research, but don't know how to fix my current one:
I want to iterate through various sub-concepts with 1 to 6 instances each.
While iterating I want to add up the instance values and bind them to
(another concept's) instance's final value. The following code specifying a
sub-concept with 3 instances works smoothly.
*CONSTRUCT* {
?A ns:HasFinalScore ?FS .
}
*WHERE* {
ns:1 ns:InstancePredicts ?A ;
ns:InstanceHasInstanceScore ?IS1 .
ns:2 ns:InstancePredictsRiskFactor ?A ;
ns:InstanceHasInstanceScore ?IS2 .
ns:3 ns:InstancePredictsRiskFactor ?A ;
ns:InstanceHasInstanceScore ?IS3 .
*BIND* (((?IS1 + ?IS2) + ?IS3) *AS* ?FS) .
}
When I try to run a template on the cub-concept that has those three
instances (as indicated with the following code), it won't work anymore.
*CONSTRUCT* {
?A ns:HasFinalScore ?FS .
}
*WHERE* {
*?this* ns:KRIPredictsRiskFactor ?A .
*?this* ns:InstanceHasInstanceScore ?IS .
?A ns:HasFinalScore ?FSold .
*BIND* ((?FSold + ?IS) *AS* ?FS) .
}
Can you guys please help me figure out what the problem is?
