Description

Advertisement pulling method, device and system and electronic equipment

Technical Field

The present disclosure relates to the field of internet technologies, and in particular, to an advertisement pulling method, an advertisement pulling device, an advertisement pulling system, and an electronic device.

Background

Stream of information (Feeds) advertisements refer to advertisements displayed in social media user friend trends or streams of informational and audiovisual media content. When a user browses information streams by using the terminal equipment, the user can trigger an advertisement pulling request through a corresponding media main background system, the terminal equipment sends the advertisement pulling request to an advertisement engine, and the advertisement engine judges whether to display advertisements and which advertisement or advertisements to display. In order to protect the user experience, the number of information flow advertisements presented per user per day is usually limited, so the advertisement engine needs to select the best several occasions to present the appropriate advertisements among several advertisement pull requests.

The related art generally pushes an advertisement to a user in response to an advertisement pull request each time the number of information streams newly acquired by the user reaches a preset value, and ignores a subsequent advertisement pull request when the number of advertisements pulled on the day exceeds a limit number. Because the behavior of browsing the information stream by the user is random, and the alternative advertisements delivered online change with time, the method can cause omission of advertisement delivery opportunities with better user experience or higher commercial value, and the advertisement delivery effect has a larger improvement space.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

The following detailed description of exemplary embodiments of the disclosure refers to the accompanying drawings.

Referring to fig. 1, the advertisement pull method 100 may include:

step S1, responding to the advertisement pulling request corresponding to the target user, and obtaining the price values of a plurality of candidate advertisements;

step S2, setting the candidate advertisement with the highest value score as a target advertisement;

step S3, obtaining the current advertisement pulling times corresponding to the target user;

step S4, when the number of times of the current advertisement can be pulled is more than zero, a value score filtering threshold value corresponding to the target user is obtained;

and step S5, when the value score of the target advertisement is larger than the value filtering threshold value, pulling the target advertisement and pushing the target advertisement to the target user.

The advertisement pulling method 100 provided by the present disclosure may be implemented by an advertisement engine. The advertisement engine is an entity connecting the media host and the advertiser, and puts the advertisement of the advertiser to an advertisement space provided by the media host, when a user accesses the media host, the advertisement pulling request is triggered by the media host background system, and the media host background system sends the advertisement pulling request to the advertisement engine for processing. A media owner refers to an entity (e.g., a circle of friends, a public number, a web portal, a news website, etc.) that owns an internet platform, and the media owner has a large user access volume (also referred to as user traffic) and inserts an advertisement space in the platform due to a desire to convert the user traffic into cash revenue.

The steps of the advertisement pull method 100 will be described in detail below.

In step S1, in response to the advertisement pull request corresponding to the target user, the value of the plurality of candidate advertisements is obtained.

In the embodiment of the present disclosure, the advertisement pull request may be triggered by a preset rule. For example, when it is determined that the number of information streams (feeds) acquired by the target user after the advertisement pull request is triggered last time exceeds a preset value, an advertisement pull request may be triggered again. The trigger rule of the advertisement pull request may also be other rules, and the disclosure is not limited thereto.

After the advertisement pulling request reaches the advertisement engine, the advertisement engine acquires the alternative advertisement at the current moment. Because the release rules of the advertisements are different, and the alternative advertisements at different times are not completely consistent, the alternative advertisement at the current time needs to be obtained in real time.

Referring to fig. 2, in one embodiment, step S1 may include:

step S11, obtaining the economic value and experience value of the alternative advertisement to the target user;

step S12, obtaining a current optimization target, and determining the weight of the economic value and the weight of the experience value according to the current optimization target;

and step S13, carrying out weighted summation according to the economic value, the weight of the economic value, the experience value and the weight of the experience value to determine the value of the alternative advertisement.

The value is used in the embodiment of the present disclosure to determine the push value of the alternative advertisement, so as to determine the alternative advertisement with the highest push value as the target advertisement to be pushed to the target user. In one embodiment, the value score of the alternative advertisement relates to both an economic value and an experience value. The economic value may be represented by eCPM (effective cost per mile), for example, and the eCPM of an alternative advertisement to a target user may be calculated by a general estimation method to estimate the advertising revenue that the alternative advertisement can obtain for each thousand impressions of the target user. The experience value may be represented by, for example, pCTR (predicted click through rate), and pCTR of an alternative advertisement for a target user may be obtained by a general evaluation method to evaluate the probability that the alternative advertisement is clicked after being pushed to the target user.

The eCPM can be used for measuring the commercial value of the alternative advertisement, the pCTR can be used for measuring the experience value of the alternative advertisement, and because the pushing scenes of the advertisement are different and the targeted users are different, the target to be realized when different advertisements are pushed is also different, sometimes the higher economic value needs to be realized when the advertisements are pushed, and sometimes the user experience needs to be taken care of when the advertisements are pushed. Therefore, in step S12, each time the value score of the candidate advertisement is determined, an optimization goal corresponding to the current advertisement pushing opportunity needs to be obtained in real time, and is more focused on the economic benefit of the advertisement or the user experience, so that the weights of the economic value and the experience value in the process of evaluating the value score of the candidate advertisement are determined according to the current optimization goal.

The current optimization target may be set by an operator in the background, may be automatically calculated according to a time period and other parameters of the user, and may also be set as a default, which is not limited in this disclosure. In some embodiments, the current optimization goal may be represented directly by a set of weight values including a weight of experience value and a weight of experience value. In other embodiments, the current optimization goal may also be represented by a word, and in step S12, the weight value set corresponding to the word may be obtained by presetting a corresponding relationship.

At step S13, the value score for an alternative advertisement may be determined by the following formula:

(1)

wherein, score is the value of the candidate advertisement, eCPM is the eCPM value of the candidate advertisement to the target user, pCTR is the pCTR value of the candidate advertisement to the target user, and θ₁And theta₂Respectively, the weight of the economic value and the weight of the experience value determined according to the current optimization goal. When the optimization objective is business value, θ can be set₁=1，θ₂=0, the eCPM of the candidate advertisement is the value thereof, and filtering by using the value filtering threshold value can achieve the goal of pulling the advertisement with a larger eCPM. Similarly, when the optimization objective is experience value, θ can be set₁=0，θ₂=1, and the pCTR of the alternative advertisement is its value at this time. For multi-objective optimization, namely balance optimization of economic value and experience value, theta can be adjusted₁And theta₂The value of (A) is calculated to reach different balance points of income and experience, and corresponding value scores are calculated to realize multi-objective optimization.

The above method for determining the value of the alternative advertisement is only an example, and those skilled in the art may determine other value calculation methods according to other optimization goals or advertisement display goals, and the disclosure is not limited in this regard.

In step S2, the candidate advertisement with the highest value score is set as the target advertisement.

By reasonably calculating the value of the alternative advertisement according to the current optimization goal, the alternative advertisement which best meets the current optimization goal and can best realize the effect represented by the current optimization goal can be screened out, namely the advertisement with the highest value score is set as the target advertisement which is ready to be pulled and pushed to the target user.

It should be noted that, although the target advertisement may not be pulled finally due to non-compliance in the subsequent condition determination process related to the number of times that the advertisement can be pulled and the value score filtering threshold corresponding to the target user, it is still necessary to determine the value of the alternative advertisement and determine the target advertisement for each advertisement pulling request as a condition for subsequently calculating the value score filtering threshold corresponding to the target user. That is, a target advertisement may be determined for each advertisement pull request, and the value score of the target advertisement may be recorded to provide conditions for subsequent data analysis.

In step S3, the current number of times of pull-able advertisements corresponding to the target user is obtained.

In the embodiment of the present disclosure, it needs to be determined whether the target user meets the hardest advertisement push condition when the current advertisement pull request is received, that is, the current number of times that the target user can pull the advertisement is determined.

Referring to fig. 3, in one embodiment, step S3 may include:

step S31, obtaining the current pulling opportunity number, the limiting pulling times and the current pulling times of the target user;

step S32, setting a maximum pull number equal to the limited pull number when the number of pull opportunities on the same day is not less than the limited pull number, and setting the maximum pull number equal to the number of pull opportunities on the same day when the number of pull opportunities on the same day is less than the limited pull number;

step S33, determining the number of times of the target user corresponding to the pull-able advertisement according to the difference between the maximum number of times of the pull-able advertisement and the number of times of the pull-able advertisement on the current day, wherein after the target advertisement is pushed to the target user, the number of times of the pull-able advertisement on the current day of the target user is increased by one.

In the embodiment of the disclosure, the number of pulling opportunities on the same day corresponding to each day of the target user may vary with the date. For example, the target user may be assigned several advertisement pull opportunities per day based on the target user's advertisement browsing behavior or information flow browsing behavior of the last day, week, or month. For users who have more information flow, more advertisements or more purchasing behaviors in recent browsing, the number of pulling opportunities on the day can be increased adaptively; for users who have less information flow in recent browsing, less advertisements in browsing or less purchasing behaviors, the number of pulling opportunities on the day can be adaptively reduced, and the like. There may be various rules for determining the number of pulling opportunities on the current day corresponding to each day of the target user, and the disclosure is not limited thereto.

The limit number of pulling is an upper limit of the number of times that the advertisement is pushed per user per day, which is set for protecting the user experience, and the number is generally set by the system and does not change with time or with the user.

The number of times that the current day has been pulled refers to the number of times that the target user has been pushed the advertisement on the current day, which is recorded by the system. The system can add one to the current day pulled times of the target user after pulling the target advertisement and pushing the target advertisement to the target user each time, so as to realize real-time update of the current day pulled times of the target user.

When the number of pulling opportunities on the current day corresponding to the target user determined according to the preset rule does not exceed the limit pulling times, determining that the maximum pulling times corresponding to the current day of the user is the number of pulling opportunities on the current day; when the number of pulling opportunities on the current day corresponding to the target user determined according to the preset rule exceeds the limited pulling times, the maximum pulling times corresponding to the current day of the user can be determined as the limited pulling times. Further, the number of times the target user has available advertisements to pull may be determined based on the difference between the maximum number of pulls and the number of times the current time point has been pulled on the day.

If the number of times of pulling the advertisement is larger than zero, the target user is proved to be in accordance with the basic condition of pulling the advertisement, and the value judgment of the next step can be carried out; if the number of times of the advertisements capable of being pulled is less than or equal to zero, the number of times of the advertisements pushed by the target user reaches the maximum number of times of pulling the advertisements on the day, and the number of times of the advertisements pushed by the target user does not meet the pushing condition of the pulled advertisements.

In step S4, when the number of times of the current advertisement that can be pulled is greater than zero, a value score filtering threshold corresponding to the target user is obtained.

The method and the device for pushing the advertisement can determine the value score filtering threshold value of the target user corresponding to the advertisement pulling request in real time according to the historical behavior of the target user, namely judge whether the target advertisement can generate enough value for the target user or not, and achieve the advertisement pushing target. The value score filter threshold is a condition that measures whether the targeted advertisement can produce a targeted value to the targeted user.

If the value filtering threshold value is set too high, error filtering is easily caused, and the advertisement filling rate is reduced; if the value filtering threshold is set too low, the target advertisement is directly displayed in response to each advertisement pulling request, and the advertisement pulling opportunity is exhausted too early, so that the advertisement with higher subsequent value score is omitted.

In order to predict an optimal advertisement pulling scheme and avoid missing better advertisement pulling opportunities, the value score filtering threshold value corresponding to the target user on the current day is determined according to analysis on the historical behavior of the target user, namely the behavior characteristics of the advertisement pulled in the last N days.

Referring to fig. 4, in one embodiment, step S4 may include:

step S41, obtaining N groups of pull advertisement characteristic values N days before the current date corresponding to the target user, wherein N is an integer greater than or equal to 1;

step S42, obtaining a filtering threshold value calculation function corresponding to the current date;

step S43, the N groups of pull advertisement feature values are substituted into the filtering threshold value calculation function to obtain an output value of the filtering threshold value calculation function, and the value score filtering threshold value is determined according to the output value of the filtering threshold value calculation function.

In the embodiment of the present disclosure, the manner of calculating the value score filtering threshold in the embodiment shown in fig. 4 may be represented by the following formula:

(2)

wherein, score_thFiltering threshold value for the value score corresponding to the current day of the target user, wherein the function f is a filtering threshold value calculation function corresponding to the current day, X_i,nThe ith characteristic value of the nth day in N days before the current date corresponding to the target user is obtained, wherein N is more than or equal to 1, N is more than or equal to 1 and less than or equal to N, and i is more than or equal to 1.

For example, if N =5 is set, and the number of a group of pull advertisement feature values corresponding to each day is 4, then when the value score filtering threshold value on the 6 th day is calculated, 5 groups of pull advertisement feature values on the 1 st, 2 nd, 3 rd, 4 th and 5 th days are obtained, that is, a total of 5 × 4=20 pull advertisement feature values is obtained. The 20 pull advertisement feature values are substituted into a filtering threshold calculation function to obtain an output value. In the embodiment of the present disclosure, the output value may be directly used as the value score filtering threshold value of the 6 th day, or may be further processed to obtain the value score filtering threshold value of the 6 th day. The above numerical values are only examples, and the number of characteristic values and the number of days can be set by a person skilled in the art, and the disclosure is not limited thereto.

Referring to fig. 5, in N days before the current date, the pulled advertisement characteristic value of the day is recorded every day according to the advertisement pulling behavior or advertisement pulling status corresponding to the target user. For convenience of calculation, the types and the number of the pull advertisement characteristic values recorded every day can be completely consistent, and only the numerical values are different according to the specific situation every day. By set form { X in FIG. 5_i,nAnd expressing the pull advertisement characteristic value corresponding to the nth day. In practical application, the number of the corresponding pull advertisement characteristic values per day can be one or more, i is greater than or equal to 1, and i is an integer. Pulling N in the advertisement characteristic value to be a relative value, namely the day relative to N days participating in calculationSay to belong to several days to use filtering threshold value calculation function of unified form to process the pulling advertisement characteristic value of N days to obtain the value score filtering threshold value corresponding to the current date. After the daily pull advertisement characteristic value is calculated, the characteristic value can be stored in a preset memory, and the subsequent flow can be directly called without repeated calculation.

Referring to fig. 6, in one embodiment, step S41 may include:

step S411, obtaining user portrait score of target user on target date, number of pulling opportunities on the same day, limited pulling times and value score of target advertisement corresponding to each pulling opportunity;

step S412, determining a value score threshold lower limit and a value score threshold upper limit of the target user on the target date according to the number of the pulling opportunities on the current day, the limited pulling times and the value score of the target advertisement corresponding to each pulling opportunity;

step S413, recording the user portrait score, the value threshold lower limit and the value threshold upper limit as a set of pull advertisement feature values of the target user on the target date.

In the embodiment shown in FIG. 6, the set of pull advertisement feature values corresponding to the target date may include, for example, 4 types of data, including user profile score, score lower threshold, score upper threshold, and number of pull opportunities on the current day for the target user on the target date.

The user portrait score of the target user on the target date can be obtained through various user portrait extraction models, and a person skilled in the art can set the extraction parameter types and model parameters of the user portrait extraction models according to actual conditions, which is not limited by the disclosure.

The "lower limit of the value score threshold" and the "upper limit of the value score threshold" are boundary values of a more reasonable value score threshold interval obtained by analyzing the number of pulling opportunities of the target date according to the value score of the target advertisement determined by all advertisement pulling requests of the target date. Because the historical data is used, the value scores of all the target advertisements corresponding to the target dates can be obtained, so that the value score threshold interval can be objectively analyzed, and no matter which of all the target advertisements corresponding to the target dates are finally pulled and pushed to the target users, the value score threshold interval obtained by analysis is not influenced by the analysis result in response to the advertisement pulling request, namely the value score threshold interval exists independently of the actual advertisement pulling condition, and is more accurate and objective.

Assuming that the number of the current-day pulling opportunities of the target user on the target date is L (namely the number of the advertisement pulling requests triggered by the target user on the target date is set to be L times), and the limiting pulling times set by the system is K, when the L is larger than or equal to K, the purpose of setting the value score filtering threshold value is to select the K times of opportunities with the maximum value score of the target advertisement in the L times of advertisement pulling requests to pull the advertisement, so as to realize the optimal advertisement putting effect; when L < K, the number of the pulling opportunities does not exceed the limited pulling times on the day, the pulling opportunities do not need to be preferred, the target advertisement can be pulled in response to each advertisement pulling request triggered by the target user, and the value filtering threshold can be set to be zero at the moment.

The value score of the target advertisement corresponding to each advertisement pulling request is scorore_n(for the advertisement engine, the value is set to positive value), the value of the target advertisements corresponding to the target date is sorted in descending order, i.e. score_n≥score_n+1. The value of the optimal threshold value is within an interval. Wherein, the upper limit of the optimal threshold is as follows:

(3)

the lower limit of the optimal threshold is:

(4)

the meaning of the formula (3) is that when L is larger than or equal to K and the pulling opportunity needs to be selected preferentially, the set value score filtering threshold value needs to ensure that the value of the target advertisement on the current day on the target date can be screened out for the maximum K times, namely the value score filtering threshold value corresponding to the target date needs to be not larger than the value of the Kth day; when L is less than K and the pulling opportunity is not required to be preferred, the set value score filtering threshold value needs to ensure that all target advertisements of the target date can be pulled, namely the value score filtering threshold value corresponding to the target date needs not to be larger than the value of the Lth maximum.

The meaning of the formula (4) is that when L is larger than or equal to K and the pulling opportunity needs to be selected preferentially, the set value score filtering threshold value needs to ensure that more than K target advertisements cannot be screened out, namely the value score filtering threshold value corresponding to the target date needs to be not smaller than the value of K +1, so as to filter out the target advertisements corresponding to the value score of K + 1; when L is less than K and there is no need to perform pull opportunity prioritization, the lower limit of the value score filtering threshold corresponding to the target date may be zero, that is, filtering of pull opportunities is not performed at all.

Therefore, the value score filtering threshold score corresponding to the target date_thShould be in

≤score_th≤

。

Within the range, the aim of selecting the pull opportunity with the largest value score for L times or K times to pull the advertisement is fulfilled.

Through the analysis, a group of pull advertisement characteristic values corresponding to the target user every day in N days before the current time can be obtained. In other embodiments of the present disclosure, the pull advertisement characteristic value may have other kinds, and the present disclosure is not limited thereto.

After the pull advertisement characteristic values corresponding to N days before the current time are determined, the pull advertisement characteristic values can be processed through a filtering threshold value calculation function acquired in real time at the current date so as to obtain a value score filtering threshold value corresponding to the current date.

In this disclosure, a parameter of a filtering threshold calculation function that enables a preset loss function value to obtain a minimum value may be solved first, and then the filtering threshold calculation function corresponding to the current date may be determined according to the parameter, where the parameter of the preset loss function includes the filtering threshold calculation function and a pull advertisement characteristic value for each day in N days before the current date corresponding to the target user. The Loss function (Loss function) is a function that maps the value of a random event or its related random variables to non-negative real numbers to represent the "risk" or "Loss" of the random event. In application, the loss function is usually associated with the optimization problem as a learning criterion, i.e. the model is solved and evaluated by minimizing the loss function.

Implementations of the filtering threshold computation function f include, but are not limited to, linear models, regression tree models, neural network models. In the model training stage of the filtering threshold calculation function f, parameters of the filtering threshold calculation function f can be obtained by solving the minimization loss function. With L_uTo represent the model loss function of the filtering threshold calculation function f corresponding to the user u, the solving formula may be, for example:

(5)

loss function L_uMay be in the form of, for example, mean square error or cross entropy. Because the value of the score filtering threshold only needs to be satisfied, the form of the loss function can be set to any one of the following forms:

(6)

(7)

in the formula (6), w₁And w₂Any constant that satisfies the condition may be set. In equation (7), Relu is a linear rectification function, defined as Relu (x) = max (x, 0). Substituting the formula (6) or the formula (7)And (5) entering the formula (5) and solving to obtain the parameters of the filtering threshold calculation function f.

The parameters of the filtering threshold calculation function f may be updated according to a preset period, for example, one week or one month. The pull advertisement characteristic value of each user in N days before the current date may be updated every day, and the value filtering threshold value is calculated using the filtering threshold value calculation function f corresponding to the current date and stored. When multiple advertisement pulling requests arrive in the current date, the value score filtering threshold value stored in the current date is directly called, and the value score filtering threshold value of the current date does not need to be repeatedly calculated in the same day.

The value score filtering threshold for the current date is calculated based on historical characteristics, but the real-time environment on the line often fluctuates compared to historical characteristics, so in one embodiment of the present disclosure, the value score filtering threshold is also corrected based on real-time information. For example, if there are a large number of advertisements with high eCPM in the same day, which results in the value score of the target advertisement pulled by the user being higher than the value score of the target advertisement pulled in the same period in the history period, the value filtering threshold needs to be adjusted up appropriately according to the current situation to ensure filtering preference; similarly, if some conditions occur in the same day, which results in a great reduction in the value scores of multiple target advertisements, the value filtering threshold needs to be reduced according to real-time conditions to ensure the filling rate of the advertisements. Therefore, in an embodiment of the present disclosure, the value score filtering threshold of the current date may be corrected in real time according to the time point corresponding to the advertisement pull request, so as to better reasonably judge whether the target advertisement should be pulled according to the advertisement competition environment of the current time point.

Referring to fig. 7, in one embodiment, step S43 may include:

step S431, obtaining a first value average value according to the value score of the pulled advertisement corresponding to a first time period of the current date, wherein the first time period is from zero point of the current date to the current time point;

step S432, obtaining a second value average value according to the value score of the pulled advertisement corresponding to the first time period of each day N days before the current date;

step S433, determining a correction coefficient according to the ratio of the first value average to the second value average;

step S434, setting the product of the correction coefficient and the output value of the filtering threshold calculation function as the value score filtering threshold.

First, a real-time value score average of the target user's current time (e.g., 0-10 hours) may be calculated_rtThat is, the average value of one or more values of the pulled advertisements of the target user up to the current time of the day is calculated to obtain score_rt(ii) a Then reads the value of all pulled advertisements for the same time period (e.g., 0-10 hours) N days before the current time, calculates the historical value score average_histThat is, values of the pulled advertisement corresponding to a first time period (e.g., 0-10 hours) of each day of the target user N days before the current time are obtained, and the values are averaged to obtain score_hist. According to the real-time value mean score_rtAnd historical value score_histThe correction coefficient is calculated as follows:

(8)

wherein,

and

the upper and lower limits of the preset correction coefficient can be adjusted by the technicians in the field according to the actual conditions. When in use

When the correction coefficient is not more than the upper limit and the lower limit of the correction coefficient, the correction coefficient is corrected

Is arranged as

(ii) a If not, then,

taking the corresponding upper and lower limits of the correction coefficient (

If the upper limit is exceeded, the upper limit is selected

，

If the lower limit is exceeded, the lower limit is removed

). The corrected value score filter threshold is:

(9)

the value score filtering threshold value corresponding to the current date is calculated according to the historical data corresponding to N days before the current date, and the correction coefficient is determined according to the historical data corresponding to the current time point, so that the value score filtering threshold value more conforming to the current advertisement competition environment and the advertisement browsing behavior of the user can be obtained.

In step S5, when the value score of the target advertisement is greater than the value filtering threshold, the target advertisement is pulled and pushed to the target user.

When the value score of the target advertisement is greater than the value score filtering threshold calculated in step S4, it may be determined that the value of the target advertisement to the target user is greater at the current date, and the advertisement delivery purpose may be better achieved, and at this time, the target advertisement may be pulled and pushed to the target user. Correspondingly, if the value score of the target advertisement does not exceed the value score filtering threshold, the pulling opportunity is given up, the advertisement pulling request is ignored, the advertisement pulling opportunity is given up for pushing the subsequent target advertisement with a higher value, and the condition that the current pulling opportunity corresponding to the target user is consumed in advance to cause the omission of the subsequent target advertisement with a higher value is avoided.

Referring to fig. 8, one column 81 corresponds to one ad pull request for a target user, each ad pull request corresponding to multiple candidate ads 811 (multiple ads in the same column). The first candidate advertisement in each column is the targeted advertisement 82 with the highest value score determined for the current ad pull request. In the plurality of columns 81, only a portion of the targeted advertisement 82 eventually becomes a pulled advertisement 83, pulled and pushed to the targeted user. As can be seen in FIG. 8, a partial ad pull request is ignored because the value score of its corresponding targeted ad 82 does not exceed the value score filter threshold for that targeted user at that time. Therefore, low-value advertisements which appear first can be prevented from being displayed, high-value advertisements which possibly appear later can be omitted, the commercial value of advertisement putting can be better improved or the experience of a user can be optimized, and the advertisement putting effect and the advertisement filling rate are effectively improved.

Referring to fig. 9, a system 900 may include:

the system comprises a plurality of user terminals 91, wherein each user terminal 91 is used for responding to a message of a user browsing information flow to trigger a plurality of advertisement pulling requests and displaying a target advertisement corresponding to at least one advertisement pulling request;

a server 92, communicatively connected to the user terminal 91, and provided with an advertisement engine, where the advertisement engine is configured to respond to an advertisement pull request to execute an advertisement pull method shown in fig. 1 to 8 to push a target advertisement to the user terminal 91;

and a memory 93 connected to the server 92 for storing the value of the target advertisement calculated by the server 92 for each advertisement pull request of each user terminal 91, the filter threshold calculation function calculated by the server, and the value score filter threshold calculated by the server for each user terminal on the current date.

In the embodiment of the present disclosure, the server 92 may be an independent physical server, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be a cloud server that provides basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a Network service, cloud communication, a middleware service, a domain name service, a security service, a CDN (Content Delivery Network), a big data and artificial intelligence platform, and the like. The terminal may be, but is not limited to, a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and the like. The terminal and the server may be directly or indirectly connected through wired or wireless communication, which is not limited by the present disclosure.

It is understood that fig. 9 is only a logical relationship illustration, in an actual deployment, the number of the user terminals 91 may be multiple, and the server 92 and the memory 93 may also be implemented by multiple hardware entities, and in some embodiments, the server 92 and the memory 93 are located in the same hardware entity.

In an application scenario, a user browses an information stream, and triggers an advertisement pull request through the user terminal 91 when a preset rule for triggering the advertisement pull request is satisfied. After receiving the advertisement pulling request, the advertisement engine disposed on the server 92 determines a target user corresponding to the advertisement pulling request, further obtains a plurality of candidate advertisements corresponding to the target user, and an economic value (eCPM) and an experience value (pCTR) of each candidate advertisement to the target user, determines value scores of the plurality of candidate advertisements according to a current optimization goal, selects the candidate advertisement with the highest value score as the target advertisement corresponding to the advertisement pulling request, and stores the value score of the target advertisement in the memory 93 for calculating a value score filtering threshold of the target user on a subsequent date.

And then, the advertisement engine determines the current times of pulling the advertisement of the target user, and when the current times of pulling is more than zero, the value score filtering threshold corresponding to the advertisement pulling request of the target user is obtained. In one embodiment, only the stored value score filtering threshold of the target user on the current date is directly called as the value score filtering threshold corresponding to the advertisement pull request, the value score filtering threshold of the current date is obtained by substituting N groups of pull advertisement characteristic values N days before the current date into a filtering threshold calculation function f, a parameter of the filtering threshold calculation function f is not changed within a preset period, the preset period may be, for example, one month or one week, and one or several pull advertisement characteristic values in a group of pull advertisement characteristic values are determined according to the value score of the target advertisement corresponding to each advertisement pull request every day stored in the memory 93. In another embodiment, a correction coefficient corresponding to the current advertisement pull request may be determined based on the value of the pulled advertisement on the current date and the pull advertisement feature value stored in the memory 93N days before the current date, and the value score filter threshold corresponding to the current advertisement pull request may be determined based on the product of the correction coefficient and the value score filter threshold of the current date.

After determining the value score filtering threshold corresponding to the advertisement pulling request, judging whether the value score of the target advertisement exceeds the value score filtering threshold, if so, pulling the target advertisement and pushing the target advertisement to the user terminal 91; if not, the advertisement pulling request is ignored.

In this application scenario, the memory 93 may be configured to store a value score of a target advertisement corresponding to each advertisement pull request per day calculated by the server 92, a filtering threshold calculation function determined by the server 92 at the beginning of each preset period, and a value score filtering threshold of the target user at the current date calculated per day by the server 92. The server 92 also reads the memory 93 to obtain historical data each time it calculates, for example, a filtering threshold function calculated and stored before it needs to be called when calculating the value filtering threshold, a value score of a target advertisement corresponding to each advertisement pull request of a target user every day needs to be called when calculating the filtering threshold calculation function, whether the value score filtering threshold of the current date needs to be read when pulling the target advertisement is determined, or further, the value score of the target advertisement corresponding to each advertisement pull request of the target user every day is read to determine the correction coefficient.
