The invention provides a triggering way and a device of promoting key words, wherein the triggering way of promoting key words includes the following steps: obtaining a query inputted by users; inputting an input sequence corresponding to the query onto a translation model to obtain an output sequence; using the output sequence to ensure the promoting key words triggered by the query; the translation model is obtained by training in advance through the following steps: obtaining the query and a clicked title corresponding to the query from the users' clicking behavior logs as training data; using the query in the training data to obtain the input sequence, using the clicked title corresponding to the query to obtain a target sequence, and training a neural network model to obtain the translation model. The triggering way and the device of promoting key words can really obtain the promoting key words corresponding to the query in semantic, and improve accuracy and recall rate triggered by the key words. 本发明提供了
