摘要

Spatio-temporal data mining is an emerging research area dedicated to the development and application of novel computational techniques for the analysis of large spatio-temporal databases. The main impulse to research in this subfield of data mining comes from the large amount of 1. spatial data made available by GIS, CAD, robotics and computer vision applications, computational biology, and mobile computing applications; 2. temporal data obtained by registering events (e.g., telecommunication or web traffic data) and monitoring processes and workflows. Both the temporal and spatial dimensions add substantial complexity to data mining tasks. First of all, the spatial relations, both metric (such as distance) and non-metric (such as topology, direction, shape, etc.) and the temporal relations (such as before and after) are information bearing and therefore need to be considered in the data mining methods.
