In data mining, association analysis mainly deals with different associations between things. Different degrees of correlation are usually treated differently in performance. In a production society, people are more interested in understanding the strong relationships between things, while ignoring weaker relationships, thereby making meaningful and valuable decisions. However, people must face several problems. For example, how to use parameters to define strong correlation; how to define meaningful parameters, this article uses experiments to explain the main factors affecting the parameters and how to select parameter values. Find the balance point where the application association produces economic value, then this balance point is a more meaningful parameter. The purpose of this article is to find the support and credibility based on association analysis through dichotomy, and compare the application analysis of the same metric value in different scenarios. Experimental results show that selecting the same parameter value in different scenarios' associated demand analysis (such as attribute association analysis) will not produce the same benefit. In the same scenario, the dichotomy method can make the parameter value close to a more meaningful value. Therefore, how to define the parameters of frequent itemsets to produce the maximum benefit is the significance of this article.
