摘要:
为了避免或者减少关联规则生成的模式中没有意义的规则,引入兴趣度作为阈值对关联规则进行完善.对兴趣度从主、客观两方面多因素进行分析,在此基础上提出了M-FIM多因素兴趣度建模,合理权衡构成兴趣模式的多个因素中的各个指标,并进行权重的确定,研究结果有助于根据不同客户对商品的不同偏好,获取有兴趣的规则,从而扩展了兴趣度的适用范围.

Abstract:
In order to avoid or reduce the useless rules in association rules, a new threshold is introduced to perfect the association rules. The interestingness is analyzed from both objective and subjective sides on multi-factors, and the M-FIM is then proposed. The indexes in multi-factors which constitute the interest measure are balanced properly and the weights are confirmed to find the different tastes of client on goods and to extend its the application areas.
