Abstract

The invention provides a user intention recognition method and device for an intelligent voice robot, and computer equipment. The method comprises the following steps: extracting candidate feature words from a historical question and answer text between the intelligent voice robot and a user, and establishing a feature database based on the candidate feature words; constructing a plurality of intention recognition models, wherein the plurality of intention recognition models comprise model parameters updated in the training process; obtaining a to-be-processed user voice text, and determining a corresponding intention recognition model; and outputting an intention prediction value of the to-be-processed user voice text by using the determined intention recognition model. The specific feature words can be effectively extracted, the feature database for user intention recognition is established, and ambiguity resolution and semantic uniformity of the specific feature words can be effectively realized; a plurality of intention sub-models for optimizing model parameters are constructed, so that the model precision can be improved; and the user intention can be identified more accurately, and finer-grained user intention mining can be realized.

Description

technical field [0001] The invention relates to the field of computer information processing, in particular to a user intention recognition method, device and computer equipment for an intelligent voice robot. Background technique [0002] At present, the communication between intelligent voice robots and users is mainly based on speech skills, and there are high requirements for the recognition of single sentence intentions. It is necessary to recognize the intentions of user sentences. Currently, commonly used algorithms include logistic regression, support vector machines, and decision trees. However, because there is a certain connection between the text before and after the statement, the currently commonly used algorithms have relatively large limitations, and there is a problem of low accuracy in identifying user intentions, resulting in an increase in user complaints. [0003] With the rapid development of network technology, massive information resources exist in th...
