Implementation of Frame System Based on Fuzzy Set Theory

要构建专家系统，我们必须获得人类专家的知识，将其表达在计算机中，并使其具有良好的用途。在本研究中，我们将格式化和实现一个模糊框架系统，以表示模糊结构和模糊值的知识，在其中我们可以将重要性值添加到插槽和确定一个模糊集作为插槽值。我们塑造了模糊的框架，并实现了原型系统。在1991年，我们评估了这个系统，并改进了它，更多的细节是下面的内容。模糊框架系统的评估：我们描述了使用模糊框架系统进行评估的多个系统。从它的经验来看，它有几个要点要改进，包括：（a）关于超级和子类的变化， （b）关于模糊继承方式的切换的介绍，（c）关于它自己模糊设置名称在一个类中的定义。为了改进这些点的实现：我们提高了上面的点，我们在程序命令中从模糊的框架系统中检索数据。我们如何在它中找到一些问题，这是一个未来的工作，可以考虑，并引入一种新的非程序命令语言。

To build expert systems, we have to acquire human expert's knowledge, represent it in an computer and make good use of it. In this research, we formulate and implement a fuzzy frame system for representing knowledge with a fuzzy structure and a fuzzy value, in which we can attach an importance value to a slot and define a fuzzy set as a slot value.In 1990, we formulated a fuzzy frame and implemented its prototype system. In 1991, we evaluated the system and improved it. More details are the followings.・Evaluation of Fuzzy Frame System : We described several systems using fuzzy frame system for evaluation. From its experience, were had several points to be improved, which include(a)a change in notations for super and sub classes, (b)an introduction of switch for a way of fuzzy inheritance, and(c)a definition of its own fuzzy set names in a class.・Implementation of the points to be improved : We improved the above points.We retrieve a data from fuzzy frame system in a procedural command. We, however, find several problems in it. It is a future work to consider and introduce a new type of non-procedural command language.
