Embodiment 1

[0047] figure 1It is a schematic flowchart of a method for determining the similarity between a query statement and a webpage provided by Embodiment 1 of the present invention. This embodiment is applicable to calculating the similarity between the query statement and the webpage after obtaining the query statement input by the user , so that the search engine can determine whether the webpage can be used as a candidate webpage in the query result based on the similarity, or rank each candidate webpage under the query statement based on the similarity.

[0048] The method can be performed by a device for determining the similarity between the query sentence and the web page, and the device can be the search engine itself that provides web page search services for users, or a third-party server that provides the search engine with the calculation of the similarity between the query sentence and the web page . see figure 1 , the method provided in this embodiment specifically ...

Embodiment 2

[0059] figure 2 It is a schematic flowchart of a method for determining the similarity between a query sentence and a web page provided by Embodiment 2 of the present invention. On the basis of Embodiment 1 above, this embodiment further adds the operation of "creating a phrase translation model". see figure 2 , the method provided in this embodiment specifically includes the following operations:

[0060] Operation 210, determine the translation bilingual pair corpus; wherein, the source language sentence of the translation bilingual pair in the translation bilingual pair corpus is a query sentence, and the target language sentence is a webpage topic sentence.

[0061] Operation 220: Train the translated bilingual corpus to create a phrase translation model; the input of the phrase translation model is a query sentence, and the output includes at least one candidate sentence having similar semantics to the input.

[0062] Operation 230, using the pre-created phrase transl...

Embodiment 3

[0076] image 3 It is a schematic flowchart of a method for determining the similarity between a query sentence and a web page provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, this embodiment will "determine the similarity between the target query sentence and the topic sentence of the web page" The operation of "is further optimized to "determine the similarity between the target query sentence and the topic sentence of the web page according to the translation probability of the candidate sentence and the similarity between the candidate sentence and the topic sentence of the web page". see image 3, the method provided in this embodiment specifically includes the following operations:

[0077] Operation 310: Translate the target query sentence into at least one candidate sentence with similar semantics through the pre-created phrase translation model.

[0078] Operation 320. Determine the similarity between the target que...

Abstract

The embodiment of the invention discloses a method and a device for determining the similarity between an inquiry sentence and a webpage, a terminal and a server. The method comprises the following steps: translating a target inquiry sentence into at least one candidate sentence having similar semantics through a pre-created phrase translation model; determining the similarity between the target inquiry sentence and a webpage topic sentence according to the similarity between the at least one candidate sentence and the webpage topic sentence, wherein the webpage topic sentence is a webpage title or a sentence for describing major webpage content obtained by resolving webpage content based on a set algorithm. By adopting the technical scheme provided by the embodiment, the webpage recall rate of any inquiry sentence by a search engine can be increased, the search engine can return webpage sets with small differences specific to inquiry sentences having different representation forms but similar semantics, and the user satisfaction of an inquiry result is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a method, a device, a terminal and a server for determining the similarity between a query statement and a web page. Background technique [0002] At present, when search engines provide users with search services, they usually first obtain the instructions entered by users in the search bar, generate query sentences based on the instructions, then calculate the correlation between the query sentences and a large number of web pages, and finally put the relevant Links corresponding to webpages with high reliability are presented to the user as the query result for the user to click to view. [0003] Since the ranking of web pages based on correlation calculation directly determines the quality of search engines and the quality of user experience, how to accurately and efficiently calculate the correlation between query statements and web page...
