    Abstract: L'invention permet de reconnaître automatiquement tout document à partir d'un petit nombre d'extractions réalisées manuellement qui servent de base pour l'apprentissage à un système automatisé. En reposant sur la construction automatique de modèles relatifs à chaque métadonnée par apprentissage automatique supervisé, le procédé selon l'invention est efficace pour traiter tout type de document et parer ainsi à la variabilité du contenu des documents. Le principe de l'invention repose sur le fait que chaque émetteur d'une pièce comptable présente son contenu d'une manière structurée et cohérente. L'invention consiste à identifier statistiquement la structure des informations contenues dans les pièces comptables produites par un émetteur et à la généraliser pour être ensuite en mesure de reconnaître les informations contenues dans toutes les pièces comptables émises par un même émetteur.

    Abstract: Methods and apparatus for determining absolute concentration values of components, a blood flow and/or a blood volume in tissue of an organ, comprising emitting radiation with at least one wavelength in the near-infrared spectrum into the tissue, generating measurement signals from detecting emerging radiation using near-infrared spectroscopy, converting, with an evaluation algorithm, a system matrix and a programmed evaluation unit, a temporal change of the detected intensities of the emerging radiation into absolute concentration values of components, introducing into the tissue an indicator having an absorption maximum in the near-infrared spectrum, and determining a temporal course of concentration values of the indicator in the tissue. Further, a mean transit time mtt is derived from the time course of the concentration values of the indicator and at least one transport function g(t) is used that characterizes blood flow in the tissue, and the blood volume is determined from the time course of concentration values of the indicator or parameters derived therefrom.
