Recherche d'informations dans les systèmes hypertextes : des représentations de la tâche à un modèle de l'activité cognitive

Abstract : In this paper we examine the cognitive and ergonomic aspects of information search in hypertext systems. Our working hypothesis is that the design of hypertext systems for education must rely on a general cognitive model of the tasks and activities concerned with complex information structures. In the first part we describe briefly several approaches to the notion of information search and we propose a categorization in three levels: Rational task model, cognitive representation, and resulting activity. In the second part we review several studies showing the influence of individual and situational factors on information search in hypertext. In the third part we propose the selection-evaluation-processing cycle as a tentative activity model of information search. We briefly discuss the possible implications of our approach for the design of hypertext systems.
