摘　　要：针对原有兴趣度度量算法的缺点,结合力学平衡原理,运用概率论、集合论等知识,提出了多事务兴趣度的度量法。具体地,采用推导和实例结合的方法详述其理论,并对此理论进行论证。论证方法采用VC++作为开发环境进行测试,以超市的实际商品为数据,用SQL SERVER存放在数据库,并且两个字段对数据进行存放。通过论证结果可以看到,此方法既综合衡量了相关度和规则准确度对规则兴趣度的影响,又克服了PS公式只适用两个事务的关联规则兴趣度度量的缺陷。In view of the shortcomings of the original interest measurement algorithm,in combination with the balance principle of mechanics and based on the knowledge of probability theory and set theory,a multitransaction interest measurement method is proposed.Specifically,the theory is expounded by a combination of derivation with example,and this theory also demonstrated.The demonstration method uses VC++as the development environment for testing,the actual commodity of the supermarket is used as data,and the SQL SERVER is stored in the database,and two fields store the data.It can be seen from the results of the argument that this method not only comprehensively measures the influence of correlation degree and rule accuracy on the interest of the rule,but also overcomes the defect that the PS formula could only be applicable to interest measurement of the association rule for two transactions.
