—In this paper, we investigate using specifically-designated spatiotemporal indexing techniques for mining co-occurrence patterns from spatiotemporal datasets with evolving polygon-based representations. Previously, suggested techniques for spatiotemporal pattern mining algorithms did not take spa-tiotemporal indexing techniques into account. We present a(More)
Mining spatiotemporal co-occurrence patterns requires assessing the strength of co-occurrences among the instances of different feature types. Currently, a spatiotemporal version of the Jaccard measure is used for measuring the strength of spatiotemporal co-occurrences. We present an extended spatiotemporal version of the Jaccard measure (<i>J*</i>) that is(More)
