Cognitive excursion analysis of uncertainty concepts based on cloud model

Based on the characteristics of human cognition and cloud model, excursion uncertain concepts by similarity between from perspective conceptual is studied. Firstly, considering different meanings numerical characters in concept, properties are given. Furthermore, order to reflect various similarities that may exist five constructed, specifically include concept expectations, entropy, hyper shape overall similarity. Secondly, rationality these proposed measurements illustrated comparing with existing methods through specific data analysis. Finally, two cognitive experiments, including processes without prior knowledge (including positive negative knowledge), designed. These experiments all used study process concepts. The experiment results show reasonable method ones, effectiveness also verified cognition.
