Abstract
The paper outlines the principles underlying the theory of polyrepresentation applied to the user's cognitive space and the information space of IR systems, set in a cognitive framework. By means of polyrepresentation it is suggested to represent the current user's information need, problem state, and domain work task or interest in a structure of causality as well as to embody semantic full-text entities by means of the principle of 'intentional redundancy'. In IR systems this principle implies simultaneously to apply different methods of representation and a variety of IR techniques of different cognitive origin to each entity. The objective is to aproximate as close as possible text retrieval to retrieval of information in a cognitive sense.
