Embodiment

[0037] For user corpus with millions of users, the iterative process of defining these user corpus intentions through business is not a one-step process. Generally, the intentions with higher priority of business requirements are defined first, and the intentions that are not defined as user corpora are other intentions, and then other intentions are defined. The user corpus further iterates new intents through the intent discovery model. For example, the intents with higher priority of business needs are: navigation, music, and weather, then the intents of other user corpora are first defined as other intents, and then new intents are iterated through the intent discovery model for user corpora of other intents, for example: through The user corpus of other intentions iterates out chatting intentions, booking intentions, Baidu Encyclopedia intentions, etc.

Abstract

The invention provides an intention discovery method and system. The intention discovery method comprises the steps that corresponding user corpora are collected according to service requirements and preprocessed; defining a corresponding intention according to the corpus of the user; constructing and training an intention recognition model according to the intention, and performing optimization; recognizing the intention of the user corpus through an intention recognition model; judging an intention type according to the current intention, and if the judged intention type is the same as the current service type, not updating the current intention; if the judged intention type does not accord with the current service type, updating through an intention discovery model to obtain a new intention; the intention discovery model is constructed and trained according to the user corpora, and is used for clustering the user corpora and then redefining the intention according to the user corpora and service requirements in the category. The intention recognition accuracy is improved through the intention recognition model. Meanwhile, the user experience of man-machine conversation is guaranteed, and the phenomenon that new intention questions and answers of the user cannot be recognized or are poor is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of intention discovery, and in particular, relates to an intention discovery method and system. Background technique [0002] Natural language is the crystallization of human wisdom, and it has been a long-standing expectation for people to interact with computers in the form of natural language. With the development of natural language processing technology and the rise of deep learning methods, the human-computer dialogue system has become a new research hotspot. In the vehicle-mounted voice interaction system, what the user says to the machine is not necessarily the originally defined intention, but may be a new intention, which will reduce the accuracy of intention recognition and the user experience of man-machine dialogue. [0003] Patent document CN109492079A (application number: CN201811173868.6) discloses an intent recognition method and device. The method includes receiving a document to ...
