A "domain-general" method for topical segmentation of a document input includes the steps of: extracting one or more selected terms from a document; linking occurrences of the extracted terms based upon the proximity of similar terms; and assigning weighted scores to paragraphs of the document input corresponding to the linked occurrences. In accordance with the present invention, the values of the assigned scores depend upon the type of the selected terms, e.g., common noun, proper noun, pronominal, and the position of the linked occurrences with respect to the paragraphs, e.g., front, during, rear, etc. Upon zero-sum normalization, the assigned scores represent the boundaries of the topical segments of the document input.
Un procédé à visée globale de segmentation topique d'une entrée document comprend les étapes suivantes; l'extraction d'au moins un terme sélectionné dans un document; la liaison des occurrences des termes extraits en fonction de la proximité de termes similaires; et l'attribution de notes pondérées à des paragraphes de l'entrée document correspondant aux occurrences liées. Selon la présente invention, les valeurs des notes pondérées dépendent du type des termes sélectionnés, par exemple, nom commun, nom propre, pronom, position des occurrences liées par rapport aux paragraphes, par exemple, avant, milieu, arrière, etc. Lors de la normalisation des sommes à zéro, les notes attribuées représentent les limites des segments topiques de l'entrée document.
