We have dealt with this situation by using AttributeAssignment, as in RDF the .1 (and .2) properties would require reification anyway. It can also cover “workshop of” or “style of” style attributions which are often uncertainty about the individual.
We resisted trying to quantify uncertainty, as from an interoperability viewpoint, there’s very little to be gained from saying that one person is 5/10 sure of an assertion whereas someone else is 4/10 certain… the temptation is to use the strength of belief as an indicator of likelihood of truth, rather than the state of mind of the asserting agent. The first would be useful but impossible, we consider the second not to be useful for interoperability between public systems. (Which is not to say it’s not valuable, just not in our scope of work) Rob On 10/3/17, 6:04 AM, "Crm-sig on behalf of martin" <[email protected] on behalf of [email protected]> wrote: Dear All, Following a request from Dominic how to deal with uncertain associations, such as "probably author of" I'd like to discuss a solution expanding properties with the "Property Class" PC and adding a "certainty value" as a ".2" property for all those cases in which the belief is the one of the maintainers of the knowledge base, in contrast to an explicit inference by a particular actor.
