Abstract

Context dependency is an important problem of knowledge. Fuzzy information also suffers from this dependency when any fuzzy concept, once described, is isolated from its context. The paper describes a cognitive model in which fuzzy knowledge is processed with respect to its surrounding context. The model is derived from some psycho-cognitive approaches: the integrity of knowledge and its context as well as the episodic character of contextual effects on knowledge. The model consists of some functional modules performing related cognitive tasks. Fuzzy knowledge is kept within a layered long-term memory. Layers form an episodic base for contextual knowledge: each layer represents a different context and keeps related fuzzy knowledge. A context selector module evaluates existence of context information in order to choose appropriate context layers. An aggregation module which is an optimization module evaluates implicit contexts. The model is supported by a car brake example, which shows its simplicity and adaptability, and thus the power of this cognitive model. The model is useful especially for mobile fuzzy system applications where knowledge on environment conditions are constantly changing and adaptation of the fuzzy system's descriptive aspects are necessary.
上下文相关模糊知识的认知模型
语境依赖是一个重要的知识问题。当任何模糊概念一旦被描述,就会与其上下文分离时,模糊信息也会受到这种依赖性的影响。本文描述了一种模糊知识根据其周围环境进行处理的认知模型。该模型来源于一些心理认知方法:知识及其情境的完整性以及情境对知识的影响的情景性。该模型由执行相关认知任务的功能模块组成。模糊知识保存在分层的长期记忆中。各层构成了上下文知识的情景基础:每层代表一个不同的上下文,并保留相关的模糊知识。上下文选择器模块评估是否存在上下文信息,以便选择适当的上下文层。聚合模块是一个计算隐式上下文的优化模块。通过一个汽车制动器实例验证了该模型的简单性和适应性,从而证明了该认知模型的强大。该模型特别适用于移动模糊系统的应用,在移动模糊系统中,环境条件的知识是不断变化的,需要对模糊系统的描述方面进行适应。
