New similarity measure for spatio-temporal OLAP queries

Abstract

Storing, querying, and analyzing spatio-temporal data are becoming increasingly important, as the availability of volumes of spatio-temporal data increases. One important class of spatio-temporal analysis is computing spatio-temporal queries similarity. In this paper, we focus on assessing the similarity between Spatio-Temporal OLAP queries in term of their GeoMDX queries. However, the problem of measuring Spatio-Temporal OLAP queries similarity has not been studied so far.Therefore, we aim at filling this gap by proposing a novel similarity measure. The proposed measure can be used either in developing query recommendation, personalization systems or speeding-up query evolution. It takes into account the temporal similarity and the basic components of spatial similarity assessment relationships.
