Discovering association patterns in large spatio-temporal databases

Over the past few years, a considerable number of studies have been made on market basket analysis. Market basket analysis is a useful method for discovering customer purchasing patterns by extracting association from stores' transaction databases. In many business of today, customer transactions can be made in many different geographical locations round the clock, especially after e-business have become prevalent. The traditional methods that consider only the association rules of an individual location or all locations as a whole are not suitable for such a multi-location environment. We design a novel and efficient algorithm for mining spatio-temporal association rules which have multi-level time and location granularities, in spatio-temporal databases. Experimental results have shown that our methods are efficient and we can find spatio-temporal association rules satisfactorilyDepartment of ComputingRefereed conference pape
