摘要
提出了一种构模知识的组织和获取方法。构模知识分为模型知识、领域知识和数据知识3个层次，数据知识是最底层的知识，高层知识的应用通过调用底层知识完成。模型知识和领域知识可以通过交互的方式在专家的帮助下获取，数据知识可以由系统自动获取。应用这种方法，系统能够在专家构建模型时获取构模的知识，从而使模型资源得到有效利用，并解决了模型管理系统知识获取的瓶颈问题。
This paper proposes a method for modeling knowledge organization and acquirement. Modeling knowledge is organized in three hierarchies: model knowledge, domain knowledge and data knowledge. Data knowledge is in the lowest level. The knowledge application in higher level is realized by calling the knowledge in low level. Model knowledge and domain knowledge can be acquired through interacting with the modeling expert, and data knowledge can be acquired automatically by the system. In this way, system can acquire modeling knowledge when the model is constructed by the expert so that model resource is effectively used.
