Abstract

Despite the fact that reasoning over time is clearly of great importance in diagnosis, prognosis and treatment planning, few medical expert systems have attempted to represent this facet of medical knowledge. This paper describes how a “time specialist” is being developed to handle the temporal aspects of problem-solving, and in particular, how it might deal with uncertainty and ambiguity in temporal relationships by using a form of Truth Maintenance.
