Abstract: L'invention concerne un procédé et un système pour le stockage dans une base de données et la récupération des données ainsi que des procédés d'obtention de profils sémantiques issus d'un corpus de textes d'apprentissage. Un réseau de neurones (103) est prévu pour extraire les profils sémantiques (109) d'un corpus de textes. Un nouveau groupe de documents extraits d'Internet est ensuite traité par le même réseau de neurones qui calcule une représentation d'un profil sémantique pour les pages web en question par le biais de relations sémantiques (106) apprises lors de l'opération de profilage des documents d'apprentissage. Ces profils sémantiques sont par la suite classés en grappes de manière à réduire au minimum la durée de réponse (109). Lorsqu'un utilisateur interroge la base de données, notamment un groupe de documents, l'interrogation est transformée en profil sémantique et comparée aux profils sémantiques de chaque grappe de documents. Le profil d'interrogation est ensuite comparé à chaque document contenu dans la grappe. Les documents dont la correspondance pondérée est la plus proche de l'interrogation sont renvoyés comme résultat de recherche.

Abstract: A crop conditioning apparatus includes two parallel fluted intermeshing rollers mounted for rotation about respective axes for passage of crop material therebetween and for movement of the axes in a direction to increase and decrease the spacing the rollers. The rollers and flutes are substantially rigid, such that rotation of the rollers while intermeshing without crop material therebetween and while out of synchronism causes unacceptable noisy contact between the flutes. Each roller being driven by a respective one of two motors arranged to generate substantially equal torque so as to tend to rotate the rollers at common angular velocity. A timing arrangement for maintaining the rollers in synchronism includes a gear wheel having a plurality of gear lobes thereon projecting radially outwardly therefrom on one roller and a disk parallel to the gear wheel with a plurality of rollers projecting outwardly from one face of the disk into a position between the gear lobes of the first member. The gear wheel is formed of a flexible material so that the lobes can flex to an amount such that the intermeshing thereof does not prevent the rollers from relative rotation caused by the presence of crop material therebetween.
