Yes, I agree. The criteria to calculate reputation depends on the context.
Therefore there should be a relationship
[Context]1-1..*>[Criteria].
I have modified the diagram like this : http://yuml.me/26953ad7

I think, now that Context has a relationship with Criteria, the
relationship between the ComputationAlgo and Context could be derived
through the Criteria entity.
