Title (EN) SYSTEMS AND METHODS FOR TEXT ATTRIBUTE DETERMINATION USING CONDITIONAL RANDOM FIELD MODEL
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTERMINATION D'ATTRIBUT DE TEXTE À L'AIDE D'UN MODÈLE DE CHAMP ALÉATOIRE CONDITIONNEL
Abstract:
(EN) A system and method for determining an attribute for each of the one or more subsets of a text, the method comprising: receiving a query from a terminal device (505); extracting a text from the query (510); determining one or more subsets of the text (520); obtaining a trained conditional random field (CRF) model (530); and determining an attribute for each of the one or more subsets of the text based on the CRF model and the each of the one or more subsets of the text (540).
(FR) L'invention concerne un système et un procédé pour déterminer un attribut pour chacun du ou des sous-ensemble d'un texte, le procédé comprenant : recevoir une requête provenant d'un dispositif de terminal (505) ; extraire un texte à partir de la requête (510) ; déterminer un ou plusieurs sous-ensembles du texte (520) ; obtenir un modèle de champ aléatoire conditionnel (CRF) entraîné (530) ; et déterminer un attribut pour chacun du ou des sous-ensembles du texte sur la base du modèle CRF et de chacun du ou des sous-ensembles du texte (540).
