Truth Maintenance in an Expert System with Uncertainty
Beata Jankowska · Schedae Informaticae · 2005
Although it is not indispensable, a truth maintenance system, or TMS, is a valuable component of an expert system. A TMS, concerned about consistency of the knowledge collected in the knowledge base, increases the reliability of conclusions obtained in a process of reasoning. The issue of TMS construction for traditional expert systems (with knowledge admitted to be certain) is well recognized from both theoretical and practical aspects. In the following paper, we present a two-level TMS project for the system with uncertainty. The presentation will be performed on the basis of an expert system used to prognosticate the effects of medical treatment of a bronchial asthma disease.
