Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 1 As shown, an embodiment of the present invention provides a modeling method of an information ranking model, including:

[0028] S11, collecting information samples;

[0029] S12. Perform sample labeling on the information sample to determine the sample correlation of the information sample;

[0030] S13, extracting sample features of the information sample, and scoring the extracted sample features to obtain a sample feature score of the information sample;

[0031] S14. Perform ranking model training by using the sample correlation degree and the sample feature score, so as to establish the ranking model.

[0032] The modeling method of the information sorting model provided by the embod...

Abstract

The invention discloses a modeling method, a ranking method, a modeling device and a ranking device for an information ranking model, and relates to the technical field of calculation and information retrieval. The modeling method, the ranking method, the modeling device and the ranking device are used for solving the problems that in the prior art, the accuracy of classified information obtained by users is low, the speed is low, and the user experience is low. The modeling method includes the steps of collecting information samples, marking the information samples so as to determine the sample relevancy of the information samples, extracting sample characteristics of the information samples, grading the extracted sample characteristics so as to obtain the sample characteristic grades of the information samples, and training the ranking model through the sample relevancy and the sample characteristic grades so as to establish the ranking model.

Description

technical field [0001] The invention relates to the technical field of computing and information retrieval, in particular to a modeling method of an information sorting model, a sorting method, a modeling device, and a sorting device. Background technique [0002] Classified information is a brand-new product form. An effective method for users to find the most suitable information from massive classified information is search technology, among which search sorting is one of the core technologies that directly affects user experience. The traditional sorting of classified information generally only sorts according to the newness of the information. [0003] This method is widely used on many information websites, because the information has issues of timeliness and tradability, so it is generally believed that the latest information is better in terms of timeliness and tradability. However, in an actual system, the most recent information does not necessarily mean that it i...
