Abstract: From a complex system perspective, the authors report a conceptual model of thinking. In this model, the knowledge forms a complex network, in which concepts form nodes, conceptual relationships form links, and propositions form network circuits. It suggests that a thinking process such as deductive reasoning corresponds to a set of network dynamical events with competing activations of network circuits under an optimization function. This conceptual model leads to a design for the next generation of expert system.

摘要: 在复杂系统研究思想指导下, 构建了基于神经元网络结构的复杂系统思维模型, 提出以网络节点表示概念, 以网络连接表示命题, 以网络回路实现知识表达, 以网络节点间的时空动力学激发实现演绎推理等思维活动的理论新框架, 并以此为基础对新一代专家系统进行了设计。
