- Abstract
- Outlines the principles underlying the theory of polyrepresentation applied to the user's cognitive space and the information space of information retrieval systems, set in a cognitive framework. Uses polyrepresentation to represent the current user's information needs, problem states, and domain work tasks or interests in a structure of causality, as well as to embody semantic full text entities by means of the principle of 'intentional redundancy'
