Les moteurs traditionnels offrent à l'utilisateur des résultats de plus en plus pertinents, mais, dans la plupart des cas, les résultats similaires ont tendance à se regrouper. L'utilisateur peut être intéressé pour retrouver des documents qui soient certes tous pertinents par rapport à sa requête, mais aussi qui soient différents les uns des autres. Dans cette thèse, nous considérons le problème de la diversité pour la recherche d'images. Nous avons focalisé notre attention sur la diversité par l'exploitation du clustering, plus spécialement par une approche hiérarchique (AHC), car sa hiérarchie de clusters peut bien correspondre à la nature hiérarchique de la diversité. De plus, nous proposons une nouvelle approche pour exploiter des ress...
