example 1

[0186] The final freshness score, FreshScore, is a fusion of the freshness of multiple predetermined dimensions. We use a linear weighting method to fuse the scores of each freshness dimension:

[0187] FreshScore=∑w i ×FreshScore i

[0188] in:

[0189] w i : weight of each dimension, satisfying ∑w i = 1,w i ≥0, the weight can be specified manually or by machine learning.

[0190] FreshScore i : Freshness value of each dimension, satisfying FreshScore i ∈[0,1]

[0191] For the freshness value of each dimension, its calculation is as shown in the following formula:

[0192]

[0193] α: Fitting coefficient, the default value is 0.1, which can be adjusted according to actual needs

[0194]β: The value range is [0,1]. The user repeatedly receives the advertisement of the same dimension, and an additional penalty is imposed on the freshness score.

[0195] CalMemory: The value range is [0,1], indicating the user's memory of the memory content of this dimension.

example 2

[0228] In this embodiment, an advertisement is used as promotion information and an industry dimension is taken as an example for illustration. Such as image 3 As shown, this example provides a method for sending promotional information, including:

[0229] Step S1: a request to pull an advertisement;

[0230] Step S2: Obtain a list of candidate advertisements;

[0231] Step S3: Judging whether there are advertisements whose freshness has not been calculated in the list of candidate advertisements, if not, the process ends, if there is, proceed to step S4;

[0232] Step S4: Select a candidate advertisement whose freshness has not been calculated;

[0233] Step S5: Extract historical data on advertisements viewed by the user, where the historical data may include the industry involved in the advertisements viewed by the user.

[0234] Step S6.1: Calculation times attenuation;

[0235] Step S6.2: Calculate the memory strength of the user;

[0236] Step S7: Calculate the i...

example 3

[0238] Such as Figure 5 As shown, this example provides a schematic diagram of an optional hardware structure of an apparatus for determining the freshness of promotional information, including a processor 11, an input / output interface 13 (such as a display screen, a touch screen, and a speaker), a storage medium 14, and a network interface 12. Components can communicate via system bus 15. Correspondingly, the storage medium 14 stores executable instructions for performing the method for determining the freshness of the promotion information described in the embodiment of the present invention. Figure 5 Each hardware module shown in can be partially implemented, fully implemented or other hardware modules can be implemented according to needs, and the number of each type of hardware module can be one or more, and each hardware module can be implemented in the same geographic location, or distributed in different geolocation implementation that can be used to perform the abo...

Abstract

An embodiment of the invention discloses a method and a device for determining the freshness of promotion information, and relates to the technical field of information. The method includes acquiring promotion information viewing historical data of users; determining the memorization strength of first promotion information according to the historical data; determining the freshness of second promotion information on preset dimensions according to the memorization strength. The first promotion information and the second promotion information are correlated to each other in the preset dimensions. The second promotion information is current to-be-promoted information. The first promotion information is the promotion information already viewed by the users. The memorization strength is used for indicating the first promotion information memorization strength of the users. The freshness is used for indicating the strangeness degree of the second promotion information. According to the technical scheme, the method and the device in the embodiment of the invention have the advantages that the freshness can be computed, accordingly, bases can be provided for determining whether the promotion information needs to be transmitted to clients or not, the promotion information can be accurately located and transmitted, and effective spreading of the promotion information can be enhanced.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for determining the freshness of promotional information. Background technique [0002] Promotional information is content that is actively pushed to users for viewing or viewing. Common promotional information may include advertisements, government announcements, and event introduction information. [0003] In the prior art, usually a promotional information will be repeatedly pushed to the same user for viewing, or similar promotional information may be pushed to one or more users in a concentrated manner, but the promotional effect of this method of pushing promotional information is not No, obviously the effective dissemination rate of this kind of information is low. In addition, repeatedly pushing the same promotional information or similar promotional information to the same or the same type of users may cause user dissatisfaction, even ca...
