Use of cognitive process modeling in knowledge base systems integration

摘要

Large and complex knowledge based systems (KBSs) are becoming increasingly common. Current surveys of these systems reveal that they are designed in four different ways: federation, emulation, alliance, and distribution. Each approach has an explicit way to integrate the essential components of the KBS. Unfortunately, the software design process to integrate components in each approach is still ad hoc and informal. As such, it is very difficult to “match” a problem description with a specific integration approach. In order to be more methodical, we propose a cognitive process model (CPM) based technique. The cognitive process model abstracts the cognitive tasks of identification, conceptualization, and formalization of the experts into one common framework. We have chosen the domain of model formulation to explain the CPM-based technique. The architectural characteristics needed to implement an integrated knowledge based system are derived from this model. Some implementation details are also shown to attest the viability of the CPM-based design.
