Abstract: A dialogue device according to an embodiment includes an acquisition unit configured to acquire a user utterance input by the user, an identification unit configured to identify a situation of the user utterance as an utterance situation, a selection unit configured to select a scenario corresponding to the user utterance from a database storing a plurality of scenarios, and an output unit configured to output a system utterance defined by the selected scenario. Each scenario defines a user utterance, a system utterance for the user utterance, and hierarchically defined scenario attributes. When two or more scenarios defining a user utterance are present as candidate scenarios in a database, the selection unit selects one scenario from the two or more candidate scenarios based on a hierarchical relationship among the two or more scenario attributes defined in the two or more candidate scenarios and the utterance situation.

Abstract: An information-processing device including an acquisition unit that acquires input data corresponding to spoken words input to a user terminal, and acquired response data output from a dialog processing device that performs processing according to the input data. A generation unit generates guidance information on how to use the dialog processing device based on the input data and the response data. An output unit outputs the guidance information generated by the generation unit to the user terminal.

Abstract: A function execution instruction system includes a function execution instruction unit configured to instruct execution of one or more functions, a sentence input unit configured to input a sentence, an execution function determination unit configured to determine a function the execution of which is instructed on the basis of an input sentence, a time information extraction unit configured to extract time information indicating a time from the input sentence, and a time specification unit configured to, in accordance with a determined function, specify a time used for the execution of the function on the basis of extracted time information wherein the function execution instruction unit instructs the execution of the determined function, which uses a specified time.

Abstract: A dialog device according to an embodiment includes an acquisition unit configured to acquire a user utterance input by a user, a plurality of generation units configured to generate a system utterance corresponding to the user utterance, and an output unit configured to output the system utterance generated by one generation unit selected from the plurality of generation units. The plurality of generation units include a first generation unit having a first scenario and a second generation unit having a second scenario different from the first scenario. The output unit outputs a first system utterance generated by the first generation unit in response to the user utterance, in a first expression format, and outputs a second system utterance generated by the second generation unit in response to the user utterance, in a second expression format different from the first expression format, following the first system utterance.

Abstract: An information-processing device includes an acquisition unit that acquires input data corresponding to spoken words input to a user terminal, and acquires response data output from a dialog processing device that perform processing according to the input data. A learning unit learns an input rule for data input to the dialog processing device based on the input data and the response data. A conversion unit converts the input data into another input data so that the input data meets the input rule that has been learned by the learning unit for the dialog processing device to which the input data is input. An output unit provides the other input data generated by the conversion unit to the dialog processing device.

Abstract: A sentence matching system includes an input unit configured to input a sentence, a matching determination unit configured to determine matching between a sentence input by the input unit and a preset matching sentence, wherein the matching sentence is configured to be divided into a plurality of character string units and at least one of the character string units includes a plurality of candidates further divided into a plurality of character strings, and the matching determination unit determines the matching by treating the input sentence as divided into the plurality of character string units.

Abstract: A sentence matching system includes an input unit configured to input a sentence, a matching determination unit configured to determine matching between the sentence input by the input unit and a preset matching sentence, wherein precision used to determine the matching in accordance with the matching sentence is set in the matching sentence, and the matching determination unit determines the matching at the precision and priority corresponding to the precision for each matching sentence.

Abstract: A dialog device according to an embodiment includes an acquisition unit configured to acquire a user utterance input by a user, a plurality of generation units configured to generate a system utterance corresponding to the user utterance, and an output unit configured to output the system utterance generated by one generation unit selected from the plurality of generation units. The plurality of generation units include a first generation unit having a first scenario and a second generation unit having a second scenario different from the first scenario. The output unit outputs a first system utterance generated by the first generation unit in response to the user utterance, in a first expression format, and outputs a second system utterance generated by the second generation unit in response to the user utterance, in a second expression format different from the first expression format, following the first system utterance.
