- public class KnowledgeSourceManager
- extends Object
This class coordinates all of the knowledge sources and finds which
ones are triggered by a given seed item.
Knowledge sources can be selected by their triggers as well as
by the type of processing they can do. For example, the system might
want to do only bottom-up processing, so it would need to ask for only
the KS's which do bottom-up processing, and then get the subset of those
that trigger. Alternatively, the system might want to check all the
knowledge sources and then choose which one to execute by judging how many
from each type have triggered.
Furthermore, each KS is associated with a package, so it can be activated
and deactivated according to this package. I am not sure that this is really
necessary, but it's in here for now...
XXX: I am not sure how processing type will be represented yet.
for now I guess each knowledge source will just have to specify a type
a string. This seems to give a little too much freedom, but I don't
want to overrestrict the types there can be before I know what I am
talking about.
