提出了一种面向主题的基于多层次空间概念的关联规则挖掘算法FT_MLSAM.在FT_MLSAM算法中,先根据用户感兴趣的主题确定挖掘的概念关系,然后对所涉及的多个空间数据层进行连接,生成空间视图,最后进行属性泛化,转化成一般属性关联规则的挖掘,实验证明算法是有效的.

In this paper,an algorithm of mining multi-level spatial association rules is presented which's based on theme.We called the algorithm as FT_MLSAM in the paper.In FT_MLSAM,it first constructs the concept relation based on the thems on which the user is interested.Second,it joins the spatial layers which are used in the data mining.Last it turns spatial association mining into association mining by attribute generalizing.It is proved right from the experiment.
