Problems solved by technology
[0003] A current search intent recognition scheme uses word vectors to semantically represent search terms. The word vectors are obtained based on the meaning of the context. However, the search terms are irregular and short in length, and some have almost no context. Poor, resulting in low final intent recognition accuracy

Embodiment Construction
[0021] With the rapid development of Internet technology, users can search all kinds of products or information they want in various websites. When users search, they leave a series of search behavior track information. By analyzing the user's search behavior, the user's search behavior can be determined. The final appeal of the user is the product or information that the user wants, that is, to determine the intention of the user's search behavior. In order to further display or push the information desired by the user to the user. The user intention recognition method provided by the present application will be described in detail below with reference to the accompanying drawings.
[0022] See figure 1 , shows a flow chart of a search intent recognition method provided by an embodiment of the present application, the method is applied to a device with computing capabilities, such as figure 1 As shown, the method mainly includes the following steps:

The invention provides a search intention recognition method and device. According to the scheme, the method comprises the steps of: performing intention recognition on a to-be-recognized search textthrough a rule model to obtain a corresponding first recognition result; and for the to-be-recognized search text of which the accuracy is lower than a first preset value, performing intention recognition again by utilizing the deep learning model to obtain a corresponding intention category; and directly determining a corresponding first identification result as an intention category corresponding to the to-be-recognized search text by utilizing the to-be-recognized search text of which the accuracy is higher than a first preset value, which is identified by the rule model. Known from the above contents, according to the scheme, multi-level recognition is carried out on the to-be-recognized search text by utilizing multiple models, the rule model is used for guaranteeing the recognition accuracy, and the deep learning model is used for recognizing data which is inaccurate or cannot be recognized by the rule model, so that the recall rate of a recognition result is guaranteed, and therefore, the finally obtained search intention recognition result is very high in accuracy and recall rate.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a search intent recognition method and device. Background technique [0002] Search intent recognition refers to dismantling and analyzing the user's search terms to obtain the user's intent and needs, so as to recommend the products or content that the user needs most. It can be seen that improving the search recognition intent can improve the accuracy of product or content recommendation. [0003] A current search intent recognition scheme uses word vectors to semantically represent search terms. The word vectors are obtained based on the meaning of the context. However, the search terms are irregular and short in length, and some have almost no context. Poor, resulting in low final intent recognition accuracy. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a search intent recognition method and device to...
