The paper describes an expert system for the assessment of the liver function. Since the system must act as an intelligent assistant for a general physician, a major emphasis has been laid upon its interactive capabilities. In particular, the user can ask the system how a given conclusion has been reached (explanation facilities) and can alter the normal operation flow. In the design of the system, the different significance and availability of the clinical data and the laboratory tests have been taken into account: The investigations about a given patient start from the clinical data, and only when there is some evidence of hepatopathy are the results of some laboratory tests requested. The final result of the investigations consists of the assessment of the liver function in terms of four aspects (biosynthesis, cholestasis, cytolysis, reactivity), each of which is assigned a linguistic value describing its impairment degree. The techniques adopted in the system are based on Artificial Intelligence methodologies augmented with linguistic terms handled according to the fuzzy set theory.
本文描述了一个用于评估肝功能的专家系统。由于该系统必须作为普通医生的智能助手，因此重点强调了其交互能力。特别是，用户可以询问系统如何得出给定的结论（解释功能），并且可以改变正常的操作流程。在系统设计中，考虑了临床数据和实验室检查的不同重要性和可用性：对给定患者的调查从临床数据开始，只有在有肝病证据时才要求进行一些实验室检查的结果。调查的最终结果包括从四个方面（生物合成、胆汁淤积、细胞溶解、反应性）对肝功能进行评估，每个方面都被赋予一个描述其损害程度的语言值。系统采用的技术基于人工智能方法，并根据模糊集理论处理语言术语进行了扩充。
