چکیده
Knowledge maintenance (KM) is the process of reflecting over some current knowledge based system in order to handle a new situation. Changes that fix new problems must not introduce bugs into old fixes. A common technique for KM is to reflect over dependencies between concepts. In this review, we sample the KM work on modeling dependencies using either a logic-based, a network-based, or a procedural-based approach.
