Methods for mining co–location patterns with extended spatial objects
Robert Bembenik, Wiktor Jóźwicki, Grzegorz Protaziuk
Abstract
The paper discusses various approaches to mining co-location patterns with extended spatial objects. We focus on the
properties of transaction-free approaches EXCOM and DEOSP, and discuss the differences between the method using a
buffer and that employing clustering and triangulation. These theoretical differences between the two methods are verified
experimentally. In the performed tests three different implementations of EXCOM are compared with DEOSP, highlighting
the advantages and downsides of both approaches.
