Automatic construction of syntactic language models for text processing systems

The article describes a formal model of the syntactic structure of texts based on generalized syntagmas and methods of its automatic construction. The proposed syntactic model is based on machine grammar which is based on the system of inflectional classes of Russian words. The correspondence between the form of the representation of words and their grammatical information, laid down in the theoretical conception of the inflectional classes of words in the Russian language, made it possible to create on this basis new classes — classes of words that have the same sets of grammatical features corresponding to their forms of representation in similar context.
