Training method of keyword generation model and keyword generation method and device

The invention discloses a keyword generation model training method and device and a keyword generation method and device, and relates to the technical field of computers, in particular to the field of artificial intelligence such as deep learning. According to the specific implementation scheme, the method comprises the steps of obtaining first training samples of multiple generation tasks; inputting the first training sample into an initial keyword generation model to obtain a first prediction keyword; and according to the difference between the first prediction keyword and the first sample keyword, training the initial keyword generation model to obtain a first keyword generation model. Therefore, by utilizing the first training samples of the multiple generation tasks, multi-target joint training is achieved, unified modeling of the multiple generation tasks is achieved, and the keyword generation model has the capacity of generating keywords with different matching relations with the query text. 本申请公开了关键词
