A task-based approach to verifying conceptual models

We propose the use of task based specifications in conceptual graphs to construct and verify a conceptual model. Task based specification methodology is used to serve as the mechanism to structure the knowledge captured in the conceptual model; whereas, conceptual graphs are adopted as the formalism to express task based specifications. Verifying a conceptual model is performed on model specifications of a task through constraint satisfaction and relaxation techniques, and on process specifications of the task based on the resolution algorithm and the notion of specificity.
