中文摘要: 基于兴趣度的规则优化算法通过整合用户领域知识,对规则进行了精简和优化,有效地帮助了用户发现其最感兴趣的规则。但算法仍存在兴趣度计算方式欠妥、用户含义表达受限等问题。提出对兴趣度计算方法的改进,对单模板情况下的计算进行分类讨论,解决了兴趣度计算不合理的问题。同时,新算法引入复合模板的技术,支持对规则的多维分析,丰富了用户含义的表达。通过2组对比实验验证,改进后的基于主观兴趣度的规则优化算法能导出更加合理的兴趣度排序结果,给用户提供更有价值的规则参考。
Abstract:In order to resolve the improper calculation method, an improvement on calculating interestingness was proposed by considering classified situations.Multiple templates were induced, which support multi-dimension analysis and enrich user’s implications. With two groups of contrast experiments, the new algorithm produced more reasonable sorting result of interestingness, and supplied users with more valuable rules.
