Problems solved by technology

[0004] For users who already know about the TV series or have watched history, their need is to find the playback link, but there are still users who have not learned about the TV series, and their needs are the introduction of the TV series. Using the existing search Among the search results output by the processing technology, the play link ranks first, and such search results do not conform to the search preferences and habits of such users

Embodiment 1

[0020] figure 1 It is a schematic flowchart of a method for generating a search result ranking model according to Embodiment 1 of the present invention. The method for generating a ranking model of search results includes the following steps:

[0021] Step 11: Establish a click weight adjustment model with multiple user characteristic parameters as training features.

[0022] Step 12: Obtain feature values ​​of multiple user features of at least one user.

[0023] The user characteristics may include, but are not limited to, at least one of the following: repeated clicks on search results, site preferences, user gender, age, occupation, job-seeking intention, location, points of interest, consumption intention, consumption ability, travel intention, health status and Pregnancy status.

[0024] According to an exemplary embodiment of the present invention, feature values ​​of multiple user features of at least one user may be acquired from a pre-established user model databa...

Embodiment 2

[0029] figure 2 It is a schematic flowchart of the search processing method in Embodiment 2 of the present invention. The method may be performed, for example, on a search engine server. The method comprises the steps of:

[0030] Step 21: Receive the user's search term.

[0031] The search term may be a search term sent from a client. For example, the user inputs "suspect tracking" on the browser search engine interface to search, and the browser application sends the search term to the search engine server.

[0032] Step 22: Obtain multiple search result items according to the search term.

[0033] A search engine server may retrieve a plurality of search result items using existing search techniques (eg, from a pre-compiled index of web pages) using the search term.

[0034] Step 23: Extract user model data of the user, where the user model data includes values ​​of multiple user characteristics of the user.

[0035] Specifically, according to the concept of the pres...

Embodiment 3

[0049] Figure 5 It is a schematic structural diagram of a search processing device according to Embodiment 3 of the present invention. Such as Figure 5 As shown, the search processing device includes:

[0050] The user search term receiving module 31 is configured to receive the user's search term.

[0051] The search result item obtaining module 32 is used to obtain multiple search result items according to the search term.

[0052] The user model data extraction module 33 is configured to extract the user model data of the user, and the user model data includes the values ​​of multiple user characteristics of the user.

[0053] The user characteristics may include at least one of the following: repeated clicks on search results, site preferences, user gender, age, occupation, job-seeking intention, location, points of interest, consumption intention, consumption ability, travel intention, health status, and pregnancy and infant status.

[0054] The influence weight acq...

Abstract

The embodiment of the invention provides a search processing method and a method and device for generating a search result ranking model. The search processing method comprises the steps of receiving a search term of a user, acquiring a plurality of search result items according to the search term, extracting user model data comprising a plurality of user feature values of the user, acquiring the impact weights of the search result items from the search result ranking model with the search result items and the user feature values as input, ranking the search result items according to the impact weights, and sending the ranked search result items. By means of the search processing method and the method and device for generating the search result ranking model, the search result can conform to the search preference and habits of the user better, and the matching degree of the search results and the user requirement is improved.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, in particular to a search processing method, a method and a device for generating a ranking model of search results. Background technique [0002] With the development of Internet applications, search processing technology is becoming more and more mature. However, the existing search applications process the search results more casually, and only consider the correlation between the search results and the search terms. [0003] For example, if a user enters the search term "suspect tracking" to search, the first ranked search result is the play link of the TV series, and the second ranked is the encyclopedia introduction of the TV series. [0004] For users who already know about the TV series or have watched history, their need is to find the playback link, but there are still users who have not learned about the TV series, and their needs are the introduction of th...
