An object-oriented approach has been applied to the different stages involved in developing a knowledge base about insulin metabolism. At an early stage the separation of terminological and assertional knowledge was made. The terminological component was developed by medical experts and represented in CORE. An object-oriented knowledge acquisition process was applied to the assertional knowledge. A frame description is proposed which includes features like states and events, inheritance and collaboration. States and events are formalized with qualitative calculus. The terminological knowledge was very useful in the development of the assertional component. It assisted in understanding the problem domain, and in the implementation stage, it assisted in building good inheritance hierarchies.
一种面向对象的方法已应用于开发胰岛素代谢知识库所涉及的不同阶段。在早期阶段，术语知识和断言知识被分离。术语部分由医学专家开发并以CORE表示。面向对象的知识获取过程应用于断言知识。提出了一种框架描述，其中包括状态和事件、继承和协作等特征。状态和事件用定性演算进行形式化。术语知识在断言部分的开发中非常有用。它有助于理解问题领域，并且在实施阶段，有助于构建良好的继承层次结构。
