One embodiment of the present invention provides a system characterizes a document with respect to clusters of conceptually related words. Upon receiving a document containing a set of words, the system selects "candidate clusters" of conceptually related words that are related to the set of words (Figure 22, 2202). These candidate clusters are selected using a model that explains how sets of words are generated from clusters of conceptually related words (Figure 22, 2204). Next, the system constructs a set of components to characterize the document, wherein the set of components includes components for candidate clusters (Figure 22, 2206). Each component in the set of components indicates a degree to which a corresponding candidate cluster is related to the set of words (Figure 22, 2208).
Un mode de réalisation de la présente invention concerne un système destiné à caractériser un document par rapport à des groupes de mots associés conceptuellement. Lors de la réception d'un document contenant un ensemble de mots, le système sélectionne des "groupes candidats" de mots associés conceptuellement associés à un ensemble de mots. Ces groupes candidats sont sélectionnés au moyen d'un modèle expliquant comment les ensembles de mots sont générés à partir de groupes de mots associés conceptuellement. Ensuite, le système construit un ensemble de composants en vue de caractériser le document, cet ensemble de composants comprenant des composants destinés à des groupes candidats. Chaque composant dans l'ensemble de composants indique un degré selon lequel un groupe candidat correspondant est associé à l'ensemble de mots.
