Abstract

The principle of polyrepresentation, proposed more than 10 years ago, provides a holistic and explicitly cognitive framework for understanding the processes involved in Information Retrieval (IR). While readily applicable to the phenomena encountered in mainstream algorithmic IR research, the main strength of the principle is that it can also be applied simultaneously to the cognitive space of the user-thus integrating the two perspectives into one coherent cognitive framework. The main idea in the principle is that document overlaps generated from representations of different cognitive and functional origins can improve performance in IR systems. This kind of overlaps we entitle "cognitive overlaps". This chapter outlines the principle of polyrepresentation with a focus on the representations involved. The potentials and problems of the principle are discussed in the light of recent empirical studies, and challenges and opportunities for future research are identified along a polyrepresentation continuum.
