Abstract

Spatial clustering provides answers for “where?” and “when?” and evokes “why?” for further explorations. In this paper, we propose a divisive multi-level clustering method that requires O(n log n)time. It reveals a cluster hierarchy for the “where?” and “when?” queries. Experimental results demonstrate that it identifies quality multi-level clusters. In addition, we present a solid framework for reasoning about multi-level clusters using Region Connection Calculus for the “why?” query. In this framework, we can derive their possible causes and positive associations between them with ease.
