Abstract

This paper describes the need for mining complex relationshipsin spatial data. Complex relationships are definedas those involving two or more of: multi-feature colocation,self-colocation, one-to-many relationships, self-exclusionand multi-feature exclusion. We demonstrate that even inthe mining of simple relationships, knowledge of complexrelationships is necessary to accurately calculate the significanceof results. We implement a representation of spatialdata such that it contains known 'weak-monotonic' properties,which are exploited for the efficient mining of complexrelationships, and discuss the strengths and limitations ofthis representation.
