Description
Technical Field
The invention relates to the technical field of internet, in particular to an advertisement pushing method and system.
Background
Frequency control in ad placement is often referred to as N + control, i.e., an ad can only be viewed by a user up to N times within a given placement period. At present, common internet advertisement systems can only perform very simple N + control basically. For example, only N + control is performed on a certain advertisement a within a certain time period T, that is, the number of times each user views the advertisement a within the advertisement delivery period T can be controlled to be at most N times. Advertisements like this are often referred to as N + advertisements.
However, the N + advertisement can only specify the maximum number of presentations within a limited time, and if the user visits frequently, the number of presentations will be used up quickly, and if the number of visits of the user is small, the advertisement that should be presented preferentially may not have an opportunity to be presented or may not be presented sufficiently. In the prior art, advertisement effect values are used for dividing advertisement putting weights, and when the method is used for controlling the advertisement putting frequency, the advertisements with different advertisement effects can only be displayed according to different proportions, and the advertisement frequency display aiming at the users cannot be adjusted according to the access habits of different users. The problem to be solved is to target advertisement display for users according to the access habits of different users and the conditions of user historical access records.
In addition, advertisement display based on N + control requires users to store data locally to complete advertisement display, which brings burden to data records of users, and can not summarize access conditions of different users to adjust the frequency of subsequent advertisement display, which brings inaccuracy of future advertisement display. How to reduce the burden of data recording of users and adjust the frequency of future advertisement display by using the total access data is also a problem to be solved.
In view of the above, the present invention is particularly proposed.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Example one
Fig. 1 is a flowchart illustrating an advertisement presentation method according to an exemplary embodiment, which may include the following steps.
In step S11, for each advertisement to be shown, obtaining an additional weight of the first access time thereof, where the additional weight of the first access time may be an initial weight;
in step S12, determining an additional weight of a second access time according to a time interval between the second access time and a first access time and an additional weight of the first access time, wherein the second access time is an access time after the first access time;
in step S13, the additional weight values of the second visit time of all the advertisements to be shown are compared, and the advertisements to be shown are determined and shown at the second visit time according to the comparison result.
In summary, in the advertisement push method provided in the embodiment of the present disclosure, the additional weight of the advertisement to be shown in the second access time of the advertisement to be shown is obtained by obtaining the additional weight of the first access time of the advertisement to be shown and combining the second access time and the time interval of the first access time, where the additional weight of the second access time represents the display priority of the advertisement, and the advertisement is shown according to the determination of the additional weight of the advertisement to be shown. The frequency of advertisement display can be changed according to the frequency of access, so that the problem of dynamic advertisement display is solved, and advertisements can be displayed more intelligently.
Example two
Fig. 2 illustrates an advertisement push method according to another exemplary embodiment, which may include the following steps.
In step S21, for each advertisement to be shown, obtaining an additional weight of the first access time thereof, where the additional weight of the first access time may be an initial weight;
the advertisement to be presented refers to the sum of all the advertisements waiting to be selected by the system for presentation, and may be an advertisement library, in which the contents of all the advertisements to be presented are stored.
All the advertisements in the advertisement library are correspondingly provided with weights, the weights are used for representing the finite stages of the advertisements when the advertisements are displayed, the first access time refers to the latest access time from the user to the present, the specific format of the access time has no clear requirement and can be year, month, day, hour, minute and second, or a time origin is set, and the access time is converted into the time counted in seconds or represented by a number with the same reference system.
The additional weight of the first access time is the additional weight corresponding to the access time of the advertisement, that is, the access weight is referred to the access time, and it is meaningless to express the access weight by deviating from the access time.
If the advertisement to be shown is a newly added delivered advertisement, the data of last access time does not exist for the advertisement to be shown, so for the newly added delivered advertisement, the additional weight corresponding to the first access time is the initial weight of the advertisement, and the initial weight is set by a system or a human, and is comprehensively determined by factors such as the price of the advertisement, the quality of an advertiser and the like.
In step S22, the additional weight of the first access time is attenuated according to the time interval between the second access time and the first access time,
obtaining a time interval between the second access time and the first access time, that is, obtaining a time interval between the current access time and the last access time, where the last access time is the closest access time to the current access time, and in short, there is no access between the second access time and the first access time.
The obtained time interval is the time naturally elapsed between the first access time and the second access time, and the unit of the time interval is second. For example, if the first access time is 11/22/15/23/30 seconds in 2017 and the second access time is 11/23/15/23/30 seconds in 2017, the time interval between the two access times is 86400 seconds. For example, exactly one day is for numerical convenience, and the number of seconds apart in practice may be any value.
After obtaining the time interval of the two visits, the additional weight of the first visit time is attenuated according to the time interval on the basis of the additional weight of the first visit time. Specifically, the additional weight of the first access time is attenuated by using a calculation formula, which is as follows:
w′n-1=wn-1*A
wherein, w'n-1Additional weighting for attenuated first access time, wn-1An additional weight for the advertisement to be presented at the first visit time, a being a decay factor that varies with the length of the time interval between the first visit time and the second visit time.
And the attenuation coefficient a is determined by the following calculation formula:
the factor is an attenuation factor of the advertisement to be displayed, the period is an attenuation period of the advertisement to be displayed, the first access time t1 is the second access time t2, and the time interval between the second access time and the first access time is t2-t1, wherein the attenuation factor is 0.9, and the attenuation period is 86400 seconds. From the formula, the attenuation coefficient can be well controlled by adjusting the attenuation factor and the attenuation period, and the attenuation factor of 0.9 and the attenuation period of 86400 seconds (namely one day) are the best implementation scheme.
In step S23, determining an additional weight of a second access time, which is an access time after the first access time, by the additional weight of the first time after the attenuation process and the initial weight;
in conjunction with step S22, the specific calculation formula for determining the additional weight of the second access time is:
wherein, wnAdditional weight for the advertisement to be shown at the second access time that needs to be determined.
This is the additional weight calculated for the nth visit at this time.
From said formula, we can derive the following,
for a new advertisement to be presented, the first visit, w1=w;
For the second access, w2=w+w1*A;
For the third access, w3=w+w2*A;
And so on.
Again, it is not difficult to conclude that when t2-t1 is less than period, d is a number less than 1, within which range the attenuation coefficient A decreases with increasing time interval, but the decrease is slower, then the base wn-1≈wn-1A means that the last presentation in the decay period will greatly affect the ranking of the presentation, with closer time distance the greater the effect.
At t2-t1 where d is a number greater than 1, greater than period, then the decay will accelerate and decay more rapidly.
Furthermore, the formula is recursive, i.e. the additional weight of the last access is not only related to the last access activity, but is related to each previous access, except that the longer the interval, the smaller the effect.
S24 comparing all the advertisement to be shown with the additional weight value of the second access time, determining and showing the advertisement to be shown according to the comparison result at the second access time
An additional weight value of the second access time can be obtained according to the calculation of the steps S22 and S23, and the additional weight value of the second access time is w in the step S23nA value of, and wnThe smaller the value of (c), the more preferentially the corresponding advertisement is shown. And adopt wnBecause of wnThe advertisement display process can be well reflected.
For example, in 360 mobile phone assistant software, the advertisement can be pushed by shaking, and each shaking is an access. The method comprises the steps that a user generates an access request every time the user shakes, the access request is sent to a server through a mobile terminal, the server records the access behavior of the user in kafka, the access behavior comprises specific access path, access time, access terminal and other information, a data processing device of the advertisement delivery system obtains access data generated by shaking of the user according to the data recorded in kafka, and the additional weight of the amount of the advertisement to be shown when the advertisement to be shown is accessed through shaking next time is calculated by combining the historical additional weight of the advertisement to be shown obtained from redis. And the server pushes the corresponding advertisement to be displayed to the mobile terminal according to the newly calculated additional weight of the next access, and the user can see the pushed advertisement on the mobile terminal.
Specifically, assuming that only two advertisements a and B are in the advertisement library to be displayed, and assuming that the initial weight w of the advertisement a is 1 and the initial weight of the advertisement B is 2, in one day (because the period is set to 1 day at present), it is basically possible to display B once after displaying a twice (calculated by substituting the above formula, the initial weight a is 1, display a, and then assume that there is one display after 1s, and the additional weight of a at this time is Slightly less than 2, still show a, accessed again at this point, with a weighting about 3, then show B, and so on).
Assuming that the A-advertisement was visited once 100 days ago, the available attenuation factor is calculatedIs 0.9100Then it may be substantially ignored or ad a may be presented. Finally, the advertisement can be ensured to be displayed infrequently in a short time, and the influence of the historical condition is small in a long time after a certain period.
The above example assumes that only two advertisements to be shown are displayed, and the selection of the display of the advertisement is performed in the same manner in the case of the advertisement library to be shown having N advertisements.
With the scheme disclosed in this embodiment, the advertisement to be displayed can be selectively displayed according to the access habits of the user, and the process of selectively displaying is not only selected according to the initial weight, but also dynamically adjusts the additional weight of the advertisement according to the access habits of the user, so as to obtain the implemented displaying process.
