Being hopelessly jet-lagged, I was thinking of the suitable definition of Reputation.
Previous one that I had in mind was around Reputation Score:
A Reputation Score of a Player (Reputee) on the Type (Criteria) by other players (Reputor) is the subjective probability assigned by the Reputor that the Reputee fulfils the Criteria.
When I think of it, I started to think that “Reputation” is after all about an assertion: assertion being a claim that some property of an identity (need not to be a human or entity) being something.
So, an abstarct definition of Reputation Score may be:
Reputation Score is a subjective probability given by a Reputation Authority of the assertion being true.
What about that?
