Abstract.

We give new definition of language as a concept and the definitions of mathematical and computer models of notions (words) of a natural language suitable for computer presenta- tion with random choice of additional objects. We propose to create interactive presentations of foundations of Turkic languages with the following aims: to offer all computer users an acquain- tance with Turkic languages without other languages as a media; to develop effective electronic text-books and complex examinations on Turkic languages; to fix their up-to-date state and to distinguish similar and same notions in them by comparing corresponding mathematical models.
