Semantic evaluation of prognostic statements on the base of probabilistic parameters

The interest in logical-semantic and semantic-information analysis of prognostic statements can be substantiated not only by the development of prognostics as such but also by the occurrence of prognostic statements in a number of empirical dissciplines where it has proved inevitable to operate with statements on the future states of the systems under investigation. Neither is it possible to overlook the fact that the prediction of future states is one of the important cognitive aims of these disciplines. The concept "prognostic statement" which will be analysed in this paper calls for a certain explication. First of all, it should be stressed that the grammatical future alone is no guarantee that a prognostic statement is involved. By prognostic statement we understand a statement made for the purpose of determining the future state of the system under investigation, future events within the given "univers de discours", etc.
