Abstract
(EN)
A video demographics analysis system selects a training set of videos to use to correlate viewer demographics and video content data. The video demographics analysis system extracts demographic data from viewer profiles related to videos in the training set and creates a set of demographic distributions, and also extracts video data from videos in the training set. The video demographics analysis system correlates the viewer demographics with the video data of videos viewed by that viewer. Using the prediction model produced by the machine learning process, a new video about which there is no a priori knowledge can be associated with a predicted demographic distribution specifying probabilities of the video appealing to different types of people within a given demographic category, such as people of different ages within an age demographic category.

La présente invention porte sur un système d'analyse démographique de vidéo qui sélectionne un ensemble de vidéos d'apprentissage à utiliser pour corréler des données démographiques de spectateur et des données de contenu vidéo. Le système d'analyse démographique de vidéo extrait des données démographiques à partir de profils de spectateur relatifs à des vidéos dans l'ensemble d'apprentissage et crée un ensemble de distributions démographiques, et extrait également des données vidéo à partir de vidéos comprises dans l'ensemble d'apprentissage. Le système d'analyse démographique de vidéo corrèle les données démographiques de spectateur avec les donnés vidéo de vidéos vues par ce spectateur. En utilisant le modèle de prédiction produit par le processus d'apprentissage automatique, une nouvelle vidéo sur laquelle il n'existe aucune connaissance a priori peut être associée à une distribution démographique prédite spécifiant des probabilités que la vidéo plaise à différents types de personnes dans une catégorie démographique donnée, telles que des personnes de différents âges dans une catégorie démographique d'âge.
