Problems solved by technology

However, since the user query sentences input in the search engine are often varied and the word order is free, the user query sentences are relatively random, so it is difficult to capture the syntactic structure of the user query sentences
Even if the capture is successful, the accuracy of the matching result is very low if the capture result is matched with the syntactic structure of the topic sentence of the webpage

Embodiment 1

[0033] Figure 1B It is a schematic flowchart of a method for determining the syntax structure of a user query statement provided by Embodiment 1 of the present invention. The method can be executed by a device for determining the syntactic structure of the user's query statement; the device is implemented by software, and can be used as a part of the search engine, which is provided in the search engine installed on the terminal, and of course can also be able to communicate with the search engine Standalone product for data communications. . see Figure 1B The method for determining the syntax structure of a user query statement provided in this embodiment specifically includes the following operations:

[0034] Operation 110: Identify the alignment relationship between the participle in the user query sentence and the participle in the preset topic sentence of the webpage.

[0035] Operation 120. Construct the syntax structure of the user query sentence according to the...

Embodiment 2

[0043] figure 2 It is a schematic flowchart of a method for determining the syntax structure of a user query statement provided by Embodiment 2 of the present invention. In this embodiment, on the basis of the first embodiment above, the operation of generating a word alignment list is further added, and the operation of identifying the word alignment relationship is optimized accordingly. see figure 2 The method for determining the syntax structure of a user query statement provided in this embodiment specifically includes the following operations:

[0044] Operation 210, acquire a sample set.

[0045] Wherein, the acquired sample set includes: a source language sample subset composed of multiple query statement samples, and a translation language sample subset composed of webpage topic sentence samples having a confidence relationship with the query statement samples.

[0046] In this embodiment, the source language sample subset includes: the historical query sentences...

Embodiment 3

[0066] image 3 It is a schematic flowchart of a method for determining the syntax structure of a user query statement provided by Embodiment 3 of the present invention. In this embodiment, aiming at the application scenario where the search engine calculates the correlation between the user query sentence and the candidate webpage topic sentence, the preset webpage topic sentence is preferably the candidate webpage topic sentence (that is, the webpage to be matched with the user query sentence) Topic Sentence). In this embodiment, on the basis of the first and second embodiments above, the operation of calculating the similarity between the syntactic structure of the user's query statement and the syntactic structure of the topic sentence of the webpage is further added. see image 3 The method for determining the syntax structure of a user query statement provided in this embodiment specifically includes the following operations:

[0067] Operation 310: Identify the align...

Abstract

An embodiment of the invention discloses a user query statement syntactic structure determining method and device. The method includes identifying the alignment relationship between the segmentation of the user query statements and the segmentation of preset webpage topic sentences; according to the alignment relationship and the syntactic structures of the webpage topic sentences, establishing the syntactic structures of the user query statements. According to the technical scheme, the syntactic structures of the user query statements can be captured in a manner of facilitating the subsequent processing, especially facilitating the subsequent measuring of correlation processing between the user query statements and webpage topic sentences to be matched.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, in particular to a method and device for determining the syntax structure of user query sentences. Background technique [0002] The core issue of search products is the correlation calculation between user query sentences (character strings entered by users to search engines) and webpage topic sentences (webpage titles, or sentences used to describe the main content of webpages obtained by parsing webpages). It is the ranking based on the correlation calculation of the webpage that determines the quality of the search engine and the quality of the user's search experience. Among them, for the user query sentences entered in the search engine, its expression forms are diverse, not only the same semantics can be expressed by different user query sentences, but also the same participle has ambiguity in different user query sentences . [0003] For example, when queryin...
