Almost want to write down something like,

## alice thinks she knows a lot about football
{ alice believes { alice cco:expertise <Football> }
} weight 0.9 .

## alice thinks bob is a pretty good football player
{ alice believes { bob cco:skill <Football> }
} weight 0.8 .

## mary thinks alice is not quite so expert as she claims
{ mary believes { alice cco:expertise <Football> }
} weight 0.6 .

A nice feature of this approach is I can refer to it
in a nested way which keeps the scope clear,

{ ww believes G1 } weight 0.2 .

where G1 is the example above - i.e. I think the example
is mostly nonsense. On the basis of this I might come up
with,

{ ww believes { bob cco:skill <Football> }
} weight 0.12 .

or, I am not particularly confident at all that bob is
a good football player on the basis of the facts
available [*]

For the specific of Bob's using CognitiveCharacteristics,
is it true that the weight goes on the characteristic
itself or does it make more sense in terms of belief
about the characteristic?

Just some ideas anyways, not immediately practical...

Cheers,

[*] average expertise of alice,
    alice_exp = (0.9 + 0.6)/2 = 0.75
skill of bob,
    skill_bob = 0.8 * alice_exp = 0.6
normalised to our confidence in things that can be
inferred from the knowledge base,
    skill_bob_norm = skill_bob * 0.2 = 0.12
