Group spatiotemporal pattern queries
Reporting the motion patterns in moving objects data has been the focus of many research projects recently. Group spatiotemporal patterns are the movement patterns, in space and time, formed by groups of moving objects, such as flocks, concurrence, encounter, etc. There exist, in the literature, smart algorithms for matching some of these patterns. These solutions, however, address specific pat...
متن کاملSpatiotemporal Pattern Queries
Capturing moving objects data is now possible and becoming cheaper with the advances in the positioning and sensor technologies. The increasing amount of such data and the various fields of applications call for intensive research work for building a spatiotemporal DBMS. This involves several aspects such as modeling the moving objects data, designing query methods, query optimization, ...etc. ...

متن کاملSpatiotemporal Queries in Database Systems
My research focuses on how to extend database technology to better support spatiotemporal applications and queries. There is now a gulf between the spatio-temporal concepts used by domain scientists and the tools provided by database systems and other commercial systems. Bridging, or at at least narrowing, this gap is universally viewed as a critical objective, but progress toward this goal has...
متن کاملCommon SpatioTemporal Pattern Analysis
In this work we present a method for the estimation of a rank-one pattern living in two heterogeneous spaces, when observed through a mixture in multiple observation sets. Using a well chosen representation for an observed set of second order tensors (matrices), a singular value decomposition of the set structure yields an accurate estimate under some widely acceptable conditions. The method pe...
