Résumé:
In this thesis I investigate an original
approach, namely the management of queries as a process relying on
events (for instance, an object enters a zone)
related to the moves of objects over a discrete representation of the
underlying space. A query is thus a
sequence of primitive events.
We introduce mobility patterns as expressions describing
such sequences of events. In the present paper we examine
specifically the following aspects of this framework:
* comparison and aggregation of moving objects trajectories, with
respect to, eventually, a multi-scale map;
* on-line classification of trajectories continuously provided by
GPS-like devices.
For each aspect, we propose a model and an evaluation technique based
on pattern-matching algorithms. A prototype validates our optimizations.
