Abstract: An adaptive dialogue system and also a computer-implemented method for semantic training of a dialogue system are disclosed. In this connection, semantic annotations are generated automatically on the basis of received speech inputs, the semantic annotations being intended for controlling instruments or for communication with a user. For this purpose, at least one speech input is received in the course of an interaction with a user. A sense content of the speech input is registered and appraised, by the speech input being classified on the basis of a trainable semantic model, in order to make a semantic annotation available for the speech input. Further user information connected with the speech input is taken into account if the registered sense content is appraised erroneously, incompletely and/or as untrustworthy. The sense content of the speech input is learned automatically on the basis of the additional user information.

Abstract: A method for operating a navigation device. The navigation device carries out a position determination on the basis of received signals. In parallel, another position determination is carried out on the basis of signals from inertial sensors. These two determined positions are compared. If these two determined positions differ by more than a predetermined amount, which has been defined by a predetermined limit value, an error value is recognized. If an impermissible deviation is recognized, then especially the direction of movement, the speed differences and the position changes are taken into account. When the error value is recognized, shaded areas in the surroundings of the vehicle are determined and associated with the determined momentary position, as a result of which an association with a lane level is carried out.

Abstract: The invention relates to a navigation method and to a navigation device. In the navigation method, the actual movement of the navigation device and thus of the user of the navigation device is detected. In order for a prescribed destination to be reached, navigation instructions are output by the navigation device. Signals that reflect the actual geometry of the surroundings can be transmitted to the navigation device by a device for detecting the surroundings. If it is recognized that output navigation instructions have not been followed, then the signals that reflect the geometry of the surroundings are detected. Based on the difference between the actual movement and the movement prescribed by the instructions, alternative navigation instructions are determined. In comparison to the originally suggested navigation instructions, the alternative navigation instructions constitute a confirmation in the direction of movement suggested by the original navigation instructions.
