A DEVELOPMENT FRAMEWORK AND VERIFICATION METHODOLOGIES FOR KNOWLEDGE-BASED SYSTEMS

Abstract

In this paper, we present a development framework and verification methodologies for knowledge-based systems (KBSs) with real-time systems as our target system. The framework originates from an integration of three software development paradigms: rapid prototyping, operational specification, and transformational implementation. Based on this framework, we present RT-FRORL as a formal requirements specification language which exploits knowledge representation techniques as an aid in the specification, development, and verification of a KBS for real-time systems. RT-FRORL uses a combination of resolution refutation, anomaly detection matrix, and algorithms methods to verify a number of properties which might exist in KBSs. By incorporating RT-FROHL and its verification methods with the underlying framework, it lays a very strong foundation to deal with the current issues in KBSs verification.
