摘要
空间co-location模式代表的是一组空间特征的子集,它们的实例在空间中频繁的关联。它是空间数据挖掘的一个重要研究方向。首先给出co-location模式的基本概念;然后描述了针对不同数据领域提出的各种算法,并重点分析了算法提出的思路及主要特点;最后对Co-location模式挖掘未来的研究方向作了探讨。
Spatial co-location patterns are traditionally defined as the subsets of features whose instances are frequently located together in geographic space .It is an important research direction for spatial data mining .Firstly ,the concepts of co-location patterns are reviewed .Then ,many popular algorithms based on different data fields are described ,which highlights the processes and dominant features of different co-location algorithms .Finally ,the future work on co-location patterns min-ing algorithms are discussed .
