In spite of the information retrieval systems performance, the electronic document production generate cognitive and information overload and disorientation. The heuristic potential of visualization gives encouraging perspectives on ability to synthesize research results, to reveal global relevance and to highlight disciplinary perception. However, precepts of visual communication and information design come up against the specific problematic of end-users perception and their multiple profiles in information use. This thesis introduce perspectives of information art as part of an instrumentalized social mediation process to improve textual retrieval system. An experiment developed within Paris 8 University library on bibliographical datas provided this research problematic.
