I work for a company that's trying to put together a useful and
user-friendly (!) belief net application. This involves representing a great
deal of probabilistic information--a priori probabilities of nodes, actual
(current) probabilities of nodes, and conditional probability tables (CPTs)
representing relationships between nodes. There is also data entry
associated with all these values.
Our research shows that the best existing applications use histograms to
show most of these things when it's easy, but that none have a friendly
interface for the entering or viewing of CPTs. Does anyone know of other
work that is being done on this problem? Any resources for graphical entry
of uncertain data in general? Any pointers would be greatly appreciated.
A lot of the work that I did a while ago for Graphical-Belief is still
(I believe) on-line. Look at

(BTW, this server has changed configuration. Links to
http://bayes.stat.washington.edu/ should be changed to
