Methods, systems and computer program products for mapping a set of related objects into a multidimensional space. The mapping is carried out using an iterative (e.g., pairwise) refinement strategy that attempts to ensure that the distances of the objects on the map satisfy a supplied set of upper and lower bounds. In a preferred embodiment, these upper and lower bounds are derived from a supplied set of relationships (similarities, dissimilarities, or proximities) between the objects. In another preferred embodiment, these distance bounds are chosen to preserve local relationships between neighboring objects while maintaining minimum separation between remote objects.

L'invention concerne des procédés, des systèmes et des produits de programmes informatiques permettant le mappage d'un ensemble d'objets reliés dans un espace multidimensionnel Ce mappage est effectué au moyen d'une stratégie de raffinement itératif (e.g., par paire) qui s'assure que les distances des objets sur la carte satisfont un ensemble donné de liaisons supérieures et inférieures. Dans un mode de réalisation préféré, ces liaison supérieures et inférieures sont issues d'un ensemble fourni de relations (similarités, différences, ou proximités) entre ces objets. Dans un autre mode de réalisation préféré, ces liaisons de distance sont choisies afin de préserver une relation locale entre des objets voisins tout en maintenant une séparation minimale entre les objets éloignés.
