Embodiment Construction

[0071] Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0072] In order to overcome the low success rate of the existing prefetch request method based on completion matching, an embodiment of the present application provides a data prefetch method, which introduces a pre-trained language model to perform query prefix input by the user. Discriminate to obtain the perplexity of the query prefix, and send a prefetch request ...

Abstract

The invention discloses a data prefetching method and device, electronic equipment and a computer readable storage medium, and relates to the field of intelligent search. The specific implementation scheme is as follows: obtaining a query prefix input by a user; judging the query prefix based on a pre-trained language model to obtain the confusion degree of the query prefix; judging whether the confusion degree is smaller than a preset threshold value or not; and when the confusion degree is smaller than the preset threshold, sending a prefetching request based on the query prefix. According to the embodiment of the invention, the prefetching request with relatively high confusion degree can be directly filtered out, so that the prefetching success rate can be improved.

Description

technical field [0001] This application relates to the field of computer technology, in particular to the field of intelligent search technology. Background technique [0002] The search prefetch function is a prefetch request for the query prefix initiated by the client before the user actually clicks the search. The prefetch result can be obtained in advance and displayed to the user, giving the user a faster search speed experience and increasing the surprise of the user. [0003] At present, the way of sending the prefetch request is mainly: send the prefetch request based on the complete matching of the query prefix input by the user. For example, when the user enters the query prefix "Liu De", the query prefix "Liu De" can be completed to "Andy Lau" to trigger the delivery of the prefetch request. Therefore, the method of issuing prefetch requests based on complementary matching often results in a large number of prefetch requests being issued when the user enters the...
