Dear Thanasis, All,

This is a good summary, but I would like to point out, that there is a fundamental distinction between ontology and uncertainty. Uncertainty is a question of knowing (epistemology), and not being (ontology) and pertains to all facts being. Therefore a solution must be generic and independent from the ontology. Another approach to have properties of uncertainty from CRM Entity and Primitive Value, and create combinations of these with the ontological ones. It is equivalent to a .2 property, but computationally efficient, and standard RDF. It only blows up the RDFS, but that can be generated automatically.

E13 introduces an additional agency, and is computationally heavy, as all reification-equivalent constructs.

All the best,

Martin

Hello,

I was asked to summarise the discussion about uncertainty with the aim to produce some guidelines on how to deal with it. Francesco has not had a chance to review this as I am sending it the last minute, but Nicola (who has also been considering the problem) had a quick look at it already.

Please find the document here:

The arguments for or against numerical values of confidence are yet to be included.

All the best,

Thanasis
