F-transform, fuzzy natural logic, tectogrammatical tree, fuzzy type theory

This paper is a contribution to the applications offuzzy logic in modeling of linguistic semantics. The topic of interest is description of the past course of a dynamical process that is given by data in the form of time series. We suggest to use the well developed technique of linguistic theory, the so called tectogrammatical trees using which linguists represent semantics of sentences. The core of the suggested procedure is construction of the tectogrammatical tree that is then assigned a formula of fuzzy natural logic. As the latterconstrues semantics of the given sentence, we can construct a model on the basis of the given data. If successful, the initial sentence can be taken as a linguistic characterization of them.
