L'HPI a d\u00e9velopp\u00e9 une plate-forme qui permet de trouver des contenus vid\u00e9o non seulement sur la base d'un titre ou de mots-cl\u00e9s, mais aussi gr\u00e2ce au contenu audiovisuel lui-m\u00eame.<\/p>\n
\"Les moteurs de recherche traditionnels atteignent ici leurs limites, car il est particuli\u00e8rement important que le contenu informatif des diff\u00e9rentes s\u00e9quences soit saisi et compris dans sa signification\".<\/em><\/p>\n explique Harald Sack, chercheur principal dans le domaine des technologies et syst\u00e8mes Internet de l'HPI. La solution est une combinaison de nouvelles m\u00e9thodes d'analyse vid\u00e9o et de technologies du web s\u00e9mantique.<\/p>\n Dans le Web s\u00e9mantique, les informations exprim\u00e9es en langage naturel sont compl\u00e9t\u00e9es par une description univoque de leur signification (s\u00e9mantique), qui peut \u00e9galement \u00eatre correctement interpr\u00e9t\u00e9e et donc comprise par des ordinateurs.<\/p>\n En enrichissant automatiquement les donn\u00e9es des films avec des informations s\u00e9mantiques, les chercheurs de l'HPI permettent \u00e0 l'utilisateur de reconna\u00eetre les liens entre les contenus des vid\u00e9os web et de les parcourir.<\/p>\n Il est ainsi possible d'utiliser des tables des mati\u00e8res visuelles ou de naviguer dans l'offre vid\u00e9o \u00e0 l'aide d'un texte audio visualis\u00e9, fourni par une reconnaissance vocale automatique.<\/p>\n Cela optimise, entre autres, l'acc\u00e8s et l'utilisation de films, d'animations informatiques, d'enregistrements de cours et de conf\u00e9rences.<\/p>","protected":false},"excerpt":{"rendered":" Comment rendre la recherche de et dans les m\u00e9dias audiovisuels tels que les vid\u00e9os web aussi simple que celle de textes ?
