Thanks Dave and Lorenz for your response.
What if we have entered the score for a student in Cryptography and
SoftwareEngineering and did not entered for Networking subject and stored
something like this in our owl file:
Student1
Name: Bob
CryptographyScore: 60
SoftwareEngineeringScore: 80
//NetworkingScore, not mentioned here
Then will the above rule fires?
No, the rule wouldn't fire in that case.

I have three subjects marks for a student.
Cryptography, Networking, Software Engineering with different marks for
each student.
I want to calculate in which subject a student got maximum marks using
Jena
rule and will set that subject as HighScoreSubject of the student (
HighScoreSubject is data propety) whose values will be one of these three
subjects.
Is this rule correct to get the required result ( I am asking this
because
I am not getting the result required)
Without seeing the data, it's always difficult to say if something is
correct or not. Sample data makes things easier.
And without knowing how you apply the rules (in a correct syntax) it's
even harder. That means, it's always good to show the relevant code.
?x rdf:type std:Student + ?x std:CryptographyScore ?score1 + ?x
std:NetworkingScore ?score2 + ?x std:SEScore ?score3 +
greaterThan(?score1,?score2), greaterThan(?score1, ?score3) -->
?x std:HighScoreSubject std:Cryptography
This rule covers only the case when the score for Cryptography is the
highest. If your data doesn't contain a student that matches the rule,
nothing will happen.

Lorenz
