    <Paragraph position="0"> In this paper we have presented a new theoretical approach to a formal description of SAA functions in the cooperative informational dialogue. It differs from the previous approaches in several ways: - two cognitive components in a participant's knowledge base are defined to represent his own knowledge as contrasted to his beliefs about his partner's state of knowledge; the rules are introduced describing the information flow relations between these components; - propositional and evaluative constituents are distinguished ill individual knowledge representation; u notion of v-eva/nation is introduced and types of cognitive states described; - a cognitive background for SAA performance is represented by one of four types of ignorance; - a typology of SAAs is proposed which distinguishes between basic and non-elementary SAAs; for each SAA type a formal representation of its informational content is given; - a scheme of information flow Js presented which shows different dialogue functions of SAAs; in this scheme a stage of introducing propositional and evaluative information and that of coordinating evaluations are considered.</Paragraph>
    <Paragraph position="1"> The limitations of the paper did not allow us to present a description of the so called particular SAAs which are opposed to the general SAAs described here by the scope and character of the propositional information under evaluation.</Paragraph>
    <Paragraph position="2"> The current description can be extended in a variety of ways: an additional research is required to define the non-elementary SAAs as a sub-class of complex speech acts; the dialogue scheme is also to he extended to include the non-elementary SAAs; the question of how to design a dialogue model allowing for types of informational contracts between the participants deserves further attention.</Paragraph>
