Abstract:
Cloud model integrates fuzziness and randomness of the qualitative concepts in the natural language. With cloud model, mapping between quantities and qualities becomes much easier and interchangeable. Based on these, a concept of similar cloud and one method of similar cloud measurement and analysis is brought forward, then the method is validated through some experiments, and the results of the experiments are discussed and analysed. In the end, it is pointed out that the similar cloud and the measurement method has some theory value and real meanings.
