Abstract :
In this paper we propose a formal framework allowing the expression of temporal trends which involve multiple granularities. We first discuss the representation of trend dependencies and then we propose a characterization of trends according to different temporal features considering also the relationships with the specific temporal granularities involved in the trend definition. A suitable temporal logic is introduced to formally represent time-evolving relations, granularities and granular trends
