Dialog System And Method With Improved Human Machine Dialog Concepts

Abstract: A dialog system according to an embodiment is provided. The dialog system comprises an input interface (105) for obtaining an input representation of an input by receiving the input and deriving the input representation from the input or by receiving the input representation, the input representation being an audio signal representation or a speech representation or a text representation, wherein the input representation comprises a plurality of input representation elements. Moreover, the dialog system comprises a preprocessor (110) for preprocessing the input representation to generate preprocessed information, such that the preprocessed information comprises a plurality of preprocessed information elements, and such that each of two or more of the plurality of preprocessed information elements depends on at least two of the plurality of information representation elements. Moreover, the dialog system comprises two or more information extraction processors (120, 123), wherein each of the two or more information extraction processors (120, 123) is suitable to generate derived information from the preprocessed information according to an information extraction rule specific for the information extraction processor, and different from an information extraction rule of any other one of the two or more information extraction processors (120, 123). Furthermore, the dialog system comprises an output interface (135) for generating an output, being an audio output and/or a textual output and/or visual output and/or being a signal for steering a machine, depending on the derived information from one or more of the two or more information extraction processors (120, 123).
