Verification of confliction and unreachability in rule-based expert systems with model checking
This addresses error detection in rule-based expert systems, but it appears incremental as it builds on existing model checking solutions.
The paper tackles the problem of detecting structural errors like confliction and unreachability in rule-based expert systems by modeling them as finite state transition systems and using model checking with UPPAAL, but no concrete performance numbers or results are provided.
It is important to find optimal solutions for structural errors in rule-based expert systems .Solutions to discovering such errors by using model checking techniques have already been proposed, but these solutions have problems such as state space explosion. In this paper, to overcome these problems, we model the rule-based systems as finite state transition systems and express confliction and unreachability as Computation Tree Logic (CTL) logic formula and then use the technique of model checking to detect confliction and unreachability in rule-based systems with the model checker UPPAAL.
