Abstract

Transactional-retail data, probably the data with the largest scientific and financial interest, still remains the most examined data category in the field of data mining. The prominent model for handling such data has long been a rather naïve one that treated items as flat Boolean variables, ordered in various ways in order to facilitate efficient counting and to reduce complexity. In this work we propose a novel view of transactional data for data mining, which is based on a spatial, a temporal or a spatiotemporal component inherent in such data. Finally we propose a method for handling this data efficiently.
