Auteur : Office québécois de la langue française,Définition
A collection of rules, procedures, and/or data used for the purpose of solving problems of a very specific type.
Notes :
Within a blackboard system, a knowledge source is an independent procedure that relates only to the blackboard and does not allow control or data to pass to/from any other knowledge source. The format of a knowledge source is similar to a production rule (i.e. a condition-action pair). The condition part will refer to the state of the blackboard, and the action part may update the blackboard with some new hypothesis.
Larger than a rule but smaller than an expert system, a knowledge source is generally a body of domain knowledge relevant to a specific problem. Thus a knowledge source is a codification applied to an expert system. In blackboard architectures, each process that has access to the shared memory is a knowledge source.Termes :
