Abstract

Summary

The history and main features of the diagnostic expert system Pro. M. D. are presented. An illustrative case report from a knowledge base for the evaluation of disorders of lipid metabolism helps to explain Pro. M. D.’s functions. The knowledge representation syntax is explained for the different types of rules. Knowledge bases currently in development are outlined. A new concept of probability reasoning and other recent improvements are discussed briefly. Implementation details are described with special regard to the inference function. Evaluation problems are discussed and Pro. M. D. is compared to other known diagnostic computer systems.

Die Entstehung und die wichtigsten Merkmale von Pro. M.D. werden vorgestellt. Ein beispielhafter Ergebnisbericht, der mit Hilfe einer Wissensbasis zur Diagnose von Fettstoffwechselstörungen erstellt wurde, erläutert die Arbeitsweise von Pro. M.D. Die Syntax der Wissensnotation wird für die verschiedenen Regeltypen erklärt. Auf die bisher entwickelten und die sich noch in Entwicklung befindlichen Wissensbasen wird eingegangen. Ein neues Konzept zur Wahrscheinlichkeitsrechnung und andere neue Verbesserungen werden kurz diskutiert. Details der Implementierung, insbesondere der Schlußfolgerungsfunktion, werden erläutert. Probleme der Evaluationen werden besprochen und eine Einordnung vergleicht Pro. M.D. mit anderen diagnostischen Computersystemen.
