J* Measure

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 (J*)
that is more relevant and efficient for the task of STCOP mining. We also demonstrate the
space and time efficiency of the J* with experimental evaluation.
