Pei,
Would you mind sharing the link (that is, if you found it on the Internet)?
Thanks,
Brad

I found the paper.
As I guessed, their update operator is defined on the whole
probability distribution function, rather than on a single probability
value of an event. I don't think it is practical for AGI --- we cannot
afford the time to re-evaluate every belief on each piece of new
evidence. Also, I haven't seen a convincing argument on why an
intelligent system should follow the ME Principle.
Also this paper doesn't directly solve my example, because it doesn't
use second-order probability.

The approach in that paper doesn't require any special assumptions, and
could be applied to your example, but I don't have time to write up an
explanation of how to do the calculations ... you'll have to read the paper
yourself if you're curious ;-)
That approach is not implemented in PLN right now but we have debated
integrating it with PLN as in some ways it's subtler than what we currently
do in the code...

I didn't know this paper, but I do know approaches based on the
principle of maximum/optimum entropy. They usually requires much more
information (or assumptions) than what is given in the following
example.
I'd be interested to know what the solution they will suggest for such
a situation.

Think about a concrete example: if from one source the system gets
P(A-->B) = 0.9, and P(P(A-->B) = 0.9) = 0.5, while from another source
P(A-->B) = 0.2, and P(P(A-->B) = 0.2) = 0.7, then what will be the
conclusion when the two sources are considered together?
There are many approaches to this within the probabilistic framework,
one of which is contained within this paper, for example...

(I have a copy of the paper but I'm not sure where it's available for
free online ... if anyone finds it please post the link... thx)
