Re: [ontolog-forum] Requesting Opinions on the Benefits of Predicates as

[Philip Jackson <philipcjacksonjr@xxxxxxxxxxx>]

Hi Frank,
 
I asked the question in response to Jack Park's email, in which he suggested a predicate instance could be a verb relating a subject and object, e.g. "X causes Y".  If this can be a first-class entity then it seems another example could be "X says (Y causes Z)", i.e. a predicate C could link two nodes A and B, where A or B may be a predicate, though not necessarily both.

 

Separately, Doug Foxvog and Simon Spero gave examples where both A and B are predicates, linked by a predicate C.
 
However, I was just asking a question, and suggesting this could be useful, not claiming to have a proof of what is or should be supported in the IF4IT standard.
 
Best,
 
Phil

Hi Phil,

You wrote: "Will a predicate C be able to link two nodes A and B that may themselves be predicates?"

I can't see (and maybe it's just because I haven't come across a tangible example) where a Predicate can cleanly link two other Predicates together.

As of now, we follow a simple rule that uses basic sentence structure to validate the integrity of the Relationship.  The sentence structure is:

SENTENCE:  "Instance of Subject (or Source) Node" is related as a/an "Predicate/Descriptor" to, of, or for "Instance of Object (or Target) Node".

You can see this in an example the example of the Semantic Relationships for this Application: http://nounz.if4it.com/Nouns/Applications/A_Application_13.SemanticRelationships.html

If you try to use a sentence structure as the validation constraint for the binding of a Source Predicate to a Target Predicate through a Binding/Descriptive Predicate, it becomes hard to create a readable/meaningful sentence.

Would you have any clear examples to prove otherwise?  I'd be very interested in learning about them.

Thanks,

Frank

Will a predicate C be able to link two nodes A and B that may themselves be predicates?
 
It seems like this would be another useful side-effect of making predicates first-class citizens...
