摘要: 定义了一种基于k-邻近对象的空间同位模式,探讨了基于k-邻近空间关系的同位模式的特点及其与基于距离阈值的空间同位模式的区别与联系,并开发了k-邻近对象同位模式挖掘算法(KNFCOM)。通过对真实数据的实验结果表明,KNFCOM算法可有效地发现大型空间数据集中存在的各种空间同位模式。Abstract: We define a k-nearest feature based on co-location patterns,and develop k-nearest feature co-location mining(KNFCOM) algorithm to mine this kind of co-location patterns.The experimental results show that KNFCOM algorithm is efficient and scalable for mining spatial co-location patterns from various large spatial datasets.
