CA 2436740

An essay is analyzed (100) automatically by accepting (110) the essay, retrieving each sentence (120) and determining (130) whether each of a predetermined set of features is present in each sentence of the essay. For each sentence in the essay a probability that the sentence is a member of a certain discourse element category is calculated (140). The probability is based on the determinations of whether each feature in the set of features is present or absent. Furthermore, based on the calculated (140) probabilities, a sentence is chosen (160) as the choice for the discourse element category.

Dans cette invention, on analyse (100) automatiquement un compte-rendu en acceptant (110) celui-ci, en extrayant chaque phrase (120) et en déterminant (130) si chacune des caractéristiques d'un ensemble de caractéristiques prédéterminé est présente dans le compte-rendu. Pour chaque phrase contenue dans le compte-rendu, on calcule (140) la probabilité que cette phrase soit un élément d'une certaine catégorie d'éléments de discours. Cette probabilité est basée sur la détermination de la présence ou de l'absence de chacune des caractéristiques de l'ensemble. Sur la base des probabilités calculées (140), on choisit (160) ensuite une phrase pour la catégorie d'éléments de discours.
