Linguistic representation of fuzzy temporal profiles

We take as a starting point the Fuzzy Temporal Profile (FTP) model, which i s used to describe the temporal evolution of a certain physical parameter. This model defines the approximation of an evolution curve by means of a se t of linear sections between a series of significant points (X-0,X-1,..., X -N), and in which each section is defined by means of an imprecise constrai nt on the duration, the increase in value and the slope between the points connected by the section. Following the FTP model we present a language for the representation of trends, the semantics of which is projected onto a f uzzy definition of each one of the constraints of a profile of interest.
