Training method and device of intention matching degree analysis model

The invention discloses a training method and device for an intention matching degree analysis model, and the method comprises the steps: obtaining a sample data set which comprises a plurality of pieces of sample data, each piece of sample data comprises a text and an intention, and each piece of sample data has a corresponding sample intention confidence coefficient; inputting the sample data into the initial model to obtain undetermined intention confidence corresponding to the sample data; and adjusting the initial model by using the difference between the undetermined intention confidence and the sample intention confidence to obtain an intention matching degree analysis model, wherein the intention matching degree analysis model is used for analyzing the matching degree of the text and the intention. The intention matching degree analysis model trained by using the method disclosed by the invention can be used for analyzing the matching degree of the text and the intention, even a new intention can be i
