Abstract: Starting from cognitive science，this paper discusses the concept space theory proposed by G?rdenfors，with the cloud model formalization of the concept space.As there are a lot of fuzzyness and uncertainty in the concept and property，this paper combines cloud model and G?rdenfors concept space model，establishes a concept space model based on the cloud theory.And the concept of similarity is defined such as to form a new method of concept space-based cloud model.An insect instance of the conceptual classification is used in model experiment of the concept space.The concept space-based cloud model validity is verified by using static and dynamic two different methods.

Key words: concept space, cloud model, cognitive science, formal concept space model

摘要： 从认知科学出发，讨论了G?rdenfors的概念空间理论，用云模型对概念空间进行了形式化研究。由于概念、属性中存在着大量的模糊性和不确定性，将云模型和G?rdenfors的概念空间模型结合起来，建立了一套基于云的概念空间模型。并进一步对概念、相似性等进行定义，形成了一套新的基于云的概念空间模型方法。通过一个昆虫分类实例来进行概念空间的建模实验。用静态和动态两种不同的方法来验证基于云模型的概念空间的有效性。
