I confirmed my understanding of "casual" by looking it up. Why would
this be a "limitation"?
That is, the expert systems do not have an understanding of the
underlying causes and effects in a system. It's much easier to program
expert systems with *shallow knowledge* based on empirical and heuristic
knowledge than with *deep knowledge* based on the basic structures,
functions, and behaviors of objects. For example, it's much easier to
program an expert system to prescribe an aspirin for a person's headache
than to program all the underlying biochemical, physiological, anatomical,
and neurological knowledge about human body..."/ In my case bioinformatics.
Gosh, does the author of these lines really think that an GP mulls
over your body's chemistry before he or she prescribes something
against your headache?
/"One type of shallow knowledge is *heuristic knowledge*."/
Agreed, according to the definition of "shallow". That's not saying
that this is an entirely bad thing.
Should I use drools planning instead just drools expert? I know that drools
planning use heuristic to score the planning problem.
I'm not sure I understand your line of thought. "Planning" is a OR
discipline, but certainly not necessarily a way to solve a problem
such as prescribing medicaments.
