A non-terminal fuzzy regular grammar is introduced and a method for its construction from a given set of sentences presented in this paper. The grammar is used to describe the relations between the occurrences of symbols in a set of sentences. It can be used to describe a set of sentences (for example a set of images with discovered elementary shapes) and such a description can be employed to retrieve similar sentences (for example images) or to analyze sentences (for example text). The fuzzy value in the grammar indicates the probability of using a given production generating a symbol and is given by the probability of the occurrence of the symbol in the set of sentences. The method of grammar construction was verified by an experimental system. Some results of experiments are presented in the paper too.
