Incorporating Backtracking in Knowledge Refinementme evidence of faults. Refinement tools typically use a hill-climbing search to identify suitable repairs. In this paper, the goal is to incorporate an effective backtracking mechanism with a refinement algorithm so that the search for repairs does not get caught by local maxima. However the repair

Verification and validation of a multistrategy knowledge-based systemons for the house renovation grant system. The development of the system followed the task structure analysis and the client centered approach. The task structure analysis describes the system at knowledge level in terms of tasks, problem solving methods and knowledge types. The implementation of th

Verification of Business Processes for a Correspondence Handling Center using CCSystems (CCS). Then we show how to verify properties such as deadlocks, livelocks, safety- and liveness properties. We demonstrate our results using examples taken from a scenario in work distribution in Correspondence Handling Centres.

User Participation-Based Software Certification), there are no generally trusted software certification schemes. While there is no theoretical reason why these safety-critical standards could not be applied to all applications, there is a practical reason: cost. Estimates vary, but it is generally accepted that a line of safety-critical software

This paper presents an approach to certifying software contained within systems where its functionality is considered critical within the environment in wh

As with any software, attention to quality and safety must be paid throughout development of a KBS and rigorous verification and validation (V&V) techniques must be employed. Research in V&V of KBS has emerged as a distinct field only in

Progressive Instantiation for the Logical Validation of Nonmonotonic KBs schema and a powerful heuristic about local search when this last one fails to prove consistency. It allows various forms of depth-limited (in)consistencies to be checked for very large .. Most notably, it allows conflicting rules and data to be discovered and reported to the knowledge engineer.
