总结 医学专家系统的优化构建需要知识工程师知识库管理的强大交互环境。关键要求包括以下技术：（a）检查现有信息，（b）添加新知识和编辑预先存在的数据结构，以及（c）检查动态内部系统行为以促进在考虑实际情况时进行调试。本文讨论了开发此类知识工程工具时的设计注意事项。重点是使用具有高密度图形接口的专业工作站，因为该技术正在迅速成为知识工程活动的主要环境。为了说明所提出的观点，我们从一个实验知识库管理工具中抽取了一些例子，该工具是为知识工程师构建 ONCOCIN 知识库而设计的，ONCOCIN 是一个为癌症患者管理提供建议的专家系统。
Summary Optimal construction of medical expert systems demands a powerful interactive environment for knowledge base management by knowledge engineers. Key requirements include techniques for (a) examining existing information, (b) adding new knowledge and editing preexisting data structures, and (c) examining dynamic internal system behavior to facilitate debugging during consideration of actual cases. This article addresses design considerations in the development of such knowledge engineering tools. The emphasis is on the use of professional workstations with high density graphics interfaces since that technology is rapidly becoming a predominant environment for knowledge engineering activities. To illustrate the points made, examples are drawn from an experimental knowledge base management tool designed for knowledge engineers constructing the knowledge base of ONCOCIN, an expert system to advise in the management of cancer patients.
