Problems solved by technology

[0002] When screening text information by searching keywords, semantic analysis of text information and keywords is usually used to judge the correlation between text information and keywords, but semantic similarity needs to rely on semantic learning of a large number of samples to obtain Higher accuracy, resulting in higher computational cost

Embodiment approach

[0039] figure 1 is an exemplary implementation of a method for pushing text information in this application, such as figure 1 As shown, the text information push method includes the following steps:

[0040] S101. Acquire a keyword group consisting of at least two keywords and at least one piece of candidate text information.

[0041] When obtaining candidate text information, the candidate text information can be predetermined text information, or it can be the candidate text information obtained after matching the keyword group with the text information to be matched. News, articles, etc. for phrase matching. Wherein, the keyword group contains at least two keywords, and the keywords can be the words entered by the user in the search box, or the keywords extracted according to the keyword extraction algorithm from the first granular text segment entered by the user in the search box, exemplary Yes, the first granularity text segment may be a sentence, that is, the user ma...

Abstract

The invention provides a text information pushing method and device, and relates to the technical field of Internet. The method comprises the steps of obtaining a keyword group composed of at least two keywords and at least one piece of candidate text information; obtaining the text information content of the candidate text information under each text information composition dimension; for each piece of candidate text information, obtaining a first hit frequency of the text information content hit by the keyword group under each text information composition dimension, and obtaining a push parameter of the candidate text information based on a weight value corresponding to each text information composition dimension and the first hit frequency corresponding to the text information composition dimension; and pushing the candidate text information to the terminal equipment based on the pushing parameters. According to the method and the device, the positions and the hit times of the keywords in the text information are considered, and different weight values are set for the composition dimensions of the text information, so that the calculated pushing parameters reflect the matching degree of the candidate text information and the keyword groups more accurately, and the candidate text information is pushed to the terminal equipment more accurately.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a text information pushing method and a device thereof. Background technique [0002] When screening text information by searching keywords, semantic analysis of text information and keywords is usually used to judge the correlation between text information and keywords, but semantic similarity needs to rely on semantic learning of a large number of samples to obtain Higher accuracy results in higher computational cost. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, an object of the present application is to propose a method for pushing text information, by obtaining a keyword group composed of at least two keywords and at least one candidate text information; obtaining the text of the candidate text information in each text information com...
