Abstract: A dialogue system including a processor, a memory, an audio input apparatus, an audio output apparatus, a touch input apparatus, and a display unit. The processor receives an input from the voice or a touch input apparatus, analyzes the content of the input, and selects a scenario corresponding to the input data from preset scenario information. The processor generates the output data specified in the scenario, calculates the priority of the input data, and determines the presence or absence of the scenario being prepared for the output data. When there is the scenario under generating the output data, the processor changes the output method of the scenario to be executed based on the priority.

Abstract: In a data collection system in which a server and a gateway are connected to each other and which includes a plurality of sensors installed on a subject of monitoring and outputting sensor data, the server selects a collection rule to change the granularity of the sensor data when it is detected on the basis of the sensor data that an abnormality or a sign of abnormality has occurred in the subject of monitoring, and the server transmits the collection rule to the gateway. The gateway acquires and manages states of the sensors, selects a first condition according to the collection rule received from the server, changes a setting for acquiring the sensor data on the basis of the first condition and the states of the sensors, acquires sensor data from the sensors on the basis of the setting, and transmits the sensor data to the server.
