FW: SWRL rule problem : y isSiblingOf y

Hi

I guess you should add a swrlb:notEqual(?x, ?y) clause and try.
since Person(?x) and Person(?y) will each match all the instances of Persons and the Person X Person space
will have (Anna, Anna) etc.. too ?

Subject: [protege-owl] SWRL rule problem : y isSiblingOf y

Hi all,

I try to use SWRL and Jess to write some basic rules... I have in my 
ontology a class "Person" and for this class the properties"hasName", 
"hasParent" and a "isSiblingOf". "isSiblingOf" is transitive and 
symmetric. I have 4 instances with the following properties :

person_1 : hasName 'Anna'
person_2 : hasName 'Michel'
person_3 : hasName 'Elise', hasParent 'person_1', hasParent 'person_2'
person_4 : hasName 'Paul', hasParent 'person_1', hasParent 'person_2'

I write the following rule to infer the "isSiblingOf" property between 
person_3 and person_4 (and the symmertic property between person_4 and 
person_3) :

Person(?x) ∧ Person(?y) ∧ hasParent(?x, ?a) ∧ hasParent(?x, ?b) ∧ 
hasParent(?y, ?a) ∧ hasParent(?y, ?b) → isSiblingOf(?x, ?y)

When I run this rule with Jess in the SWRL Tab, the result is 4 
"isSiblingOf" properties ! I obtain the 2 correct properties between 
person_3 and person_4 but also a wrong "isSiblingOf" between person_3 
and himself and person_4 and himself...

Where these two inferred properties come from (from my OWL ontology or 
from the SWRL rule) ? Where is the error with this ? Any idea ?

Thanks for your help,

Re: Ontology from database schema?

Hi Jennifer,

thanks. I installed the 2.0b version and it worked. As you said, I had
to convert the original Frames project to OWL afterwards.

Also thanks for the information provided on the Wiki.

Regards,
Andy
