Method and device for generating search prompt

Abstract

The embodiment of the invention provides a method and a device for generating a search prompt. The method for generating the search prompt comprises the following steps: acquiring a search keyword ofa user; generating a candidate prompt set of search keywords according to the search keywords; generating a data feature of each candidate prompt by using a search keyword and each candidate prompt inthe candidate prompt set; inputting the data feature into a pre-trained score prediction model to obtain the score of each candidate prompt; and determining a target prompt for a search keyword fromthe set of candidate prompts according to the score. The score of each candidate prompt is extracted by the score prediction model, No manual weight setting is avoided, the problems of unreasonable weight setting and inaccurate scores of candidate prompts are solved, and the scores of candidate prompt s can be objectively calculated according to the historical behavior of the user, so that the prompts are more in line with the wishes of the user, and the user can select the desired prompts from the prompts, thereby improving the efficiency of information searching.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for generating search prompt words. Background technique [0002] With the rapid development of the Internet, the network has become an indispensable part of people's daily life, study and work. Network information disseminates rapidly, and there is a large amount of network information, how users can quickly retrieve useful information from a large amount of information is very important. User input hints are also called search hints, which are a way to improve retrieval efficiency by giving users complete hint words by inputting part of the query information in the search box. [0003] Currently, search prompt words are mainly generated from different sources such as pinyin prefixes, simplified spelling prefixes, and prompt word prefixes of the prompt words. Specifically, first calculate the matching degree between the search keyword and the prompt...

Problems solved by technology

[0004] However, the current method of generating prompt words requires artificially assigning different values ​​for the matching degree between the search keyword and the prompt word, the search volume of the prompt word, whether the prompt word is an album on the site, the click-through rate of the prompt word, and the novelty of the prompt word. Weights often lead to excessive weights assigned to prompt words with a large search volume, or to suppress the weight of more popular prompt words in order to prevent cheating, or when the empirical formula calculates that the matching degree of two prompt words is consistent, the prompt words cannot be adjusted. The phenomenon of sorting, resulting in the problem that the prompt words generated according to the sorting do not match the user's search keywords and do not meet the user's wishes, making the user unable to choose among the prompt words, and the prompt words lose the meaning of prompting
