Service-oriented robot intention recognition device and training and recognition method thereof

The invention discloses a service-oriented robot intention recognition device and training and recognition method thereof, and the method comprises the following steps: 1) determining a dialogue intention to be recognized according to an application scene, obtaining a large amount of dialogue data and a corresponding intention, manually finding out the corresponding intention in the dialogue data, and carrying out the corpus labeling; 2) obtaining a stop word list by adopting an expected cross entropy quantization algorithm, and removing stop words in the dialogue; 3) constructing a device for intention recognition and training the device through the training set data processed in the steps (1) and (2), and (4) obtaining the dialogue data processed in the steps (1) and (2) in real time through the trained device, performing intention recognition and outputting the best intention The intention recognition method is high in intention recognition efficiency, high in accuracy, strong in generalization ability and
