Can you elaborate a bit more on that?
This is one of the best uses for Jess's limited backward chaining
facility. Jess "knows" when certain facts that don't exist would
activate some rules. Using backward chaining rules, you can hook into
this knowledge and supply just those needed facts in a "just-in-time"
manner (perhaps by querying for just the right information from a
database.) This way you don't have to load in the whole big dataset
at once -- just what is needed.
