Abstract

The embodiment of the invention discloses a retrieval method and device. The method comprises the specific steps of receiving an information acquisition request sent by a client side, wherein the information acquisition request comprises target text input by a user; parsing the target text, and generating the characteristic information of the target text; inputting the characteristic information to a pre-trained keyword generation model, and obtaining keywords of the target text, wherein the keyword generation model is used for characterizing the corresponding relation between text and keywords; conducting retrieval with the obtained keywords as retrieval words, and sending a retrieval result back to the client side. The method improves the retrieval flexibility.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, especially to a retrieval method and device. Background technique [0002] With the development of computer technology, online shopping has penetrated into every aspect of people's lives. Usually, the user needs to input text (such as a phrase including product name, model, etc.) in the page to search for product information. [0003] The existing methods usually directly use all the text entered by the user as the search term for information retrieval. When the text entered by the user is long or there are spelling errors in the text, it is usually impossible to retrieve valid information. Therefore, this retrieval method There is a problem of low flexibility. Contents of the invention [0004] The purpose of the embodiments of the present application is to propose an improved retrieval method and device to solve the technical pro...
