RE: Model and sources of uncertainty

Vipul's issues:

 

Statement vs. belief: Perhaps we could incorporate beliefs in the ontology, but
this would seem to say that someone makes statements that he/does not believe
in. It seems to me that in that case the distinction would be between the agent
who believes in the statment and someone else who just refers to that agent's
beliefs. We could possibly subclassify Statement for this purpose. Vipul - could
you say in OWL what changes you are proposing?

 

[VK] I think we are thinking along the same lines... Here is an attempt to
describe in OWL what I mean ...

 

Maybe Belief is a superclass of Statement .. Then the issue about saying
something you believe in would not happen...

 

Statement subClassOf BeliefOrHypothesis

Agent hasBelief BeliefOrHypotheses

BeliefOrHypothesis believedBy Agent

 

StatementOfAgent = Statement AND (some saidBy Agent)

BeliefOfAgent = Statement AND (some believedBy Agent)

 

If you allow someone to say things he doesn't believe in...

StatementOfAgent and BeliefOfAgent do not have a subClassOf/superClassOf
relationship between them,.

 

Class Evidence

BeliefOrHypothesis isBasedOn Evidence

 

StatementByAgent subClassOf Evidence

BeliefOfAgent subClassOf Evidence

 

Class Interpretation

Interpretation subClassOf (some interprets Statement)

 

Agent interprets Statement

Statement interpretedby Agent

 

(believedBy)* subPropertyOf believedBy /* not sure */

saidBy o believedBy subPropertyOf believedBy /* not sure */

 

Need to axiomatize belief/evidence chaining somehow.... 

but am not sure that the above is the right way to do it?

Also need to introduce the notion of Evidence...
