基于SQL的多值多层关联规则挖掘

在分析研究关系数据库上关联规则挖掘现有方法的基础上,提出了一种基于结构化查询语言SQL的多值多层关联规则挖掘新方法。采用了一种新的根据概念分层的编码方法对多值属性进行离散化,然后利用SQL的查询语句,结合多值属性的编码,实现了关系数据库上的多层关联规则挖掘。实验表明,该算法具有快速、有效、易开发等优点。

SQL-Based Multi-Value Multilayer Mining Association Rules Excavation

On the basis of the analysis of the present algorithms about data mining of association rules in relational database,proposes one new method of multilayered association rules excavation based on the structured inquiry language SQL.First introduce a new coding method of concept lamination for multi-valued attributes discrete,then use SQL the inquiry sentence,combining multivalued attribute coding,to achieve multilayer mining association rules in relational database.Experiments show that this algorithm has many advantages,such as quickness,effectiveness,ease to develop,etc.
