Referring to fig. 3, fig. 3 is a schematic flowchart of an alternative method for recommending multimedia information according to an embodiment of the present invention, and the steps shown in fig. 3 will be described.
S101, the server receives an exposure request.
S102, the server acquires preset quantity-keeping configuration information according to the user information carried in the exposure request.
S103, the server acquires first multimedia information based on preset quantity-of-protection configuration information; wherein the multimedia information to be exposed comprises first multimedia information.
And S104, the server screens out a candidate multimedia information set from the multimedia information to be exposed according to a preset screening threshold, wherein the candidate multimedia information set contains first multimedia information conforming to the target conservation duty ratio.
S105, the server determines exposure multimedia information based on the candidate multimedia information set.
And S106, the server pushes the exposed multimedia information to the terminal.
And S107, the terminal displays the exposed multimedia information in the current page.
In the case that the embodiment of the invention is applied to the scene of Feed stream recommendation, a multimedia information recommendation device is taken as a server as an example for explanation. When a user loads multimedia information on a current page of the terminal (for example, performs a refresh information operation on the current page, etc.), that is, the terminal generates an exposure request and sends the exposure request to the server, and the server implements a recommendation process of the multimedia information to be exposed.
In S101, the server receives an exposure request sent by the terminal, where the exposure request is used to request the multimedia information displayed on the current page, and the server needs to respond to the exposure request to implement selection of the exposed multimedia information.
In the embodiment of the invention, in order to ensure certain exposure of specific multimedia information, the multimedia information is selected by adopting the operation of the protection. The specific multimedia information may be understood as multimedia information requiring a certain exposure, and in the embodiment of the present invention, the first multimedia information and the representation of the first sub-multimedia information refer to the specific multimedia information.
In S102, the exposure request received by the server carries user information, where the user information may be information characterizing characteristics and conditions of the user, such as feature data corresponding to the user, and the server may select preset amount-keeping configuration information satisfied by the user information according to the user information, where the preset amount-keeping configuration information characterizes the amount-keeping condition, and only when the user information is in compliance with the amount-keeping condition, the exposure request is given to specific multimedia information requiring amount keeping. It should be noted that the preset amount of the configuration information may be stored in an amount of the configuration information base, and for different users, a matching amount of the configuration information base may be found, that is, the preset amount of the configuration information.
For example, the preset amount of configuration information may be a man, a middle-aged, etc., and the embodiment of the present invention is not limited.
In the embodiment of the present invention, the specific multimedia information is the multimedia information about which a sufficient exposure needs to be ensured, and the preset amount of protection configuration information may include configuration information of the supported amount of protection directional crowd, the amount of protection, and the like.
In S103, the quality assurance process may be divided into four stages (as shown in fig. 4A-4C): recall, coarse ranking, fine ranking, mixed ranking, and the multimedia message to be exposed can be advertisement, video or news, etc., and the embodiment of the invention is not limited. In the embodiment of the invention, the server can adopt an independent link to carry out the quality-preserving process in the coarse arranging stage (fig. 4A), or adopt an independent link to carry out the quality-preserving process in the fine arranging stage (fig. 4B), or adopt an independent link to carry out the quality-preserving process in both the coarse arranging stage and the fine arranging stage (fig. 4C), and adopt the distribution sequence and the service rate to determine the first exposure multimedia information in the mixed arranging stage so as to determine the exposure multimedia information. In the recall phase, the server marks the multimedia information that needs to be protected, i.e., the specific multimedia information, with a protection mark for distinguishing the specific multimedia information from the non-specific multimedia information (second multimedia information). The server may obtain preset amount-of-protection configuration information corresponding to the agreed multimedia information which wants to be saved in the current period by using feature data, user interests or big data analysis corresponding to the user of the terminal, and recall other multimedia information (second multimedia information) according to the recall policy. In the embodiment of the invention, the server acquires the specific multimedia information (the multimedia information to be exposed) in the recall stage, namely, the first multimedia information, and the specific multimedia information is acquired from a multimedia information database (such as an advertisement or an article put in) through a separate link based on the preset quantity-of-protection configuration information after the server acquires the preset quantity-of-protection configuration information. The multimedia information to be exposed in the embodiment of the invention can comprise the first multimedia confidence acquired based on the preset quantity-of-protection configuration information and the second multimedia information which is the nonspecific multimedia information acquired based on the recall strategy.
That is, in the embodiment of the present invention, the multimedia information recalled by the server and including the specific multimedia information is the multimedia information to be exposed. The multimedia information to be exposed comprises specific multimedia information for the protection, namely first multimedia information, recalled through an independent link according to preset protection configuration information.
It should be noted that, in the embodiment of the present invention, the specific multimedia data may be multimedia information belonging to different contracted users, so that the specific multimedia information may be classified into at least one of the guaranty sets, and the specific multimedia information in different guaranty sets may be marked as the same guaranty mark, and the characteristics belong to the same lot of guaranty information. In the response process of one exposure request, the specific multimedia information may be the multimedia information in multiple quality-preserving sets, that is, the server needs to determine the first sub-multimedia information with enough exposure amount (i.e. the specific multimedia information that can be exposed at the last of the mixed-arrangement stage) from the specific multimedia information in different batches.
In S104, the server acquires recalled multimedia information to be exposed, and the number of specific multimedia information in the recalled multimedia information to be exposed can be statistically determined, so that the server can screen out a candidate multimedia information set from the multimedia information to be exposed based on the specific multimedia information and a preset screening threshold, wherein the candidate multimedia information set includes first sub-multimedia information conforming to the target quality-keeping ratio.
The preset screening threshold is used for representing the quantity of the multimedia information which needs to be screened from the multimedia information to be exposed and enters the mixed arrangement stage. The target quality-preserving ratio characterizes a proportion of the first multimedia information to the first sub-multimedia information reserved to the shuffling stage.
It should be noted that, the preset screening threshold includes: the target guard ratio comprises a first guard ratio and a second guard ratio.

In the embodiment of the invention, the server can acquire the total exposure of the previous period, for example, the total exposure of yesterday to specific multimedia information, in the process of carrying out the quality-preserving processing of the current period or the recommendation of the multimedia information.
Further, the total exposure of the previous cycle may also be an average total exposure of each cycle counted in a historical time, which is not limited in the embodiment of the present invention.
For the first mode, the server determines a first retention ratio based on the ratio of the number of the first multimedia information to the total exposure of the previous period, wherein the first retention ratio represents the reserved retention information proportion of the current period predicted based on the total exposure of the previous period, then the first multimedia information with the first retention ratio is ensured to enter a candidate set of the next fine-ranking stage in the coarse-ranking stage based on the first retention ratio and a first preset screening threshold, and then the server performs fine-ranking screening on the fine-ranking candidate multimedia information set in the fine-ranking stage to obtain the candidate multimedia information set. In the fine-ranking stage, the server can adopt a second preset screening threshold value to screen out candidate multimedia information sets meeting the second preset screening threshold value from the fine-ranking candidate multimedia information sets, and the fine-ranking stage does not carry out the quality assurance of specific multimedia information, but only carries out total screening on the multimedia information entering the fine-ranking stage.
It can be understood that the server performs one-time quality-preserving processing on the specific multimedia information in the coarse-ranking stage, and retains the specific multimedia information with certain requirements to enter the fine-ranking stage, so that the probability of the specific multimedia information entering the next stage in the coarse-ranking stage is ensured, certain ensured specific multimedia information is provided for screening in the fine-ranking stage, and the exposure of the specific multimedia information is influenced and improved to a certain extent.

Aiming at the third mode, the server determines a first conservation rate based on the ratio of the number of the first multimedia information to the total exposure of the previous period, wherein the first conservation rate represents the reserved conservation information proportion of the current period predicted based on the total exposure of the previous period, then the server ensures that the specific multimedia information with the first conservation rate enters a candidate set of the next fine-ranking stage in the coarse-ranking stage based on the first conservation rate and a first preset screening threshold value, thereby realizing the conservation processing of the specific multimedia information once, and then the server can determine the candidate multimedia information set of the first sub-multimedia information which is reserved with the second conservation rate of the specific multimedia information from the fine-ranking candidate multimedia information set based on a second preset screening threshold value, thereby realizing the conservation processing of the second specific multimedia information.
It can be understood that the server performs primary quality-preserving processing on the specific multimedia information in the coarse-ranking stage and performs secondary quality-preserving processing on the specific multimedia information in the fine-ranking stage, so that the specific multimedia information with certain requirements is reserved in the layer-by-layer screening stage of the specific multimedia information and enters the mixed-ranking stage, the probability of exposing the specific multimedia information in the mixed-ranking stage is ensured, certain ensured specific multimedia information is provided for exposing and screening in the mixed-ranking stage, and the exposure of the specific multimedia information is improved.
That is, the server performs the quality-preserving process of an individual link in the coarse-ranking stage, so as to obtain a fine-ranking candidate multimedia information set with a first preset screening threshold, where the fine-ranking candidate multimedia information set further includes fine-ranking first multimedia information conforming to the first quality-preserving ratio. Here, the server continues to perform the second quality-preserving process on the fine-grained first multimedia information in each quality-preserving set using a separate link.
In some embodiments of the present invention, the server may determine, from the fine-ranked candidate multimedia information sets, a candidate multimedia information set that retains the first sub-multimedia information that conforms to the second retention ratio based on a second preset screening threshold.
In some embodiments of the present invention, for the server in the first and third modes, based on the total exposure of the previous period and the first preset screening threshold, an implementation process of screening the fine-ranking candidate multimedia information set from the multimedia information to be exposed includes: and determining a first conservation rate based on the ratio of the quantity of first multimedia information in the multimedia information to be exposed to the total exposure of the previous period, wherein the first conservation rate represents the reserved conservation information proportion of the current period predicted based on the total exposure of the previous period, and then ensuring that the first multimedia information with the first conservation rate enters a candidate set of the next fine-ranking stage in the coarse-ranking stage based on the first conservation rate and a first preset screening threshold.
In some embodiments of the present invention, the server determines a first duty cycle corresponding to the multimedia information to be exposed based on the total exposure of the previous period; determining the quantity of the fine-ranking multimedia information corresponding to the fine-ranking candidate multimedia information set based on the multimedia information to be exposed and a first preset screening threshold; determining the quantity of the precisely-arranged first multimedia information based on the quantity of the precisely-arranged multimedia information and the first maintenance ratio; selecting fine-ranking first multimedia information of the fine-ranking first multimedia information quantity from the first multimedia information, and selecting fine-ranking second multimedia information from the multimedia information to be exposed; and taking the fine-ranking first multimedia information and the fine-ranking second multimedia information as fine-ranking candidate multimedia information sets.
In the embodiment of the invention, the first preset screening threshold is the number of the multimedia information from the coarse stage to the fine stage, and the 4 stages are funnel type layer-by-layer filtering multimedia information. The value of the first preset screening threshold is preset, and the embodiment of the invention is not limited.
In the embodiment of the present invention, the server may select the fine-ranked first multimedia information occupying the first retention ratio for the first multimedia information to the next stage, but the number of fine-ranked first multimedia information reaching the first preset screening threshold for entering the fine-ranked stage must not be enough, so that the fine-ranked second multimedia information with the (1-first retention ratio) proportion needs to be selected from the information (second multimedia information) of the multimedia information to be exposed, except for the specific multimedia information, to enter the information processing of the fine-ranked stage. The number of fine-grained multimedia information is the same value as the first preset screening threshold.
Here, the server needs to select the fine-ranking multimedia information of the first preset screening threshold from the multimedia information to be exposed, so that the amount of the fine-ranking multimedia information is the first preset screening threshold.
Further, for the first multimedia information, the process of selecting the fine-ranking candidate specific multimedia information with the first conservation duty ratio from the first multimedia information is as follows: the server determines the quantity of the fine-ranking first multimedia information based on the quantity of the fine-ranking first multimedia information and the first conservation duty ratio, then selects the fine-ranking first multimedia information of the quantity of the fine-ranking first multimedia information from the first multimedia information according to a preset screening rule, selects the fine-ranking second multimedia information from the multimedia information to be exposed, and finally uses the fine-ranking first multimedia information and the fine-ranking second multimedia information together as a fine-ranking candidate multimedia information set to enter the information processing of a fine-ranking stage.
Note that, the fine-ranked first multimedia information is multimedia information conforming to (1-first allowance ratio) which is screened from the second multimedia information.
In the rough ranking stage, the server first calculates a pool of reserved retention amounts (corresponding to the first retention ratio) according to the total yesterday exposure amount (total exposure amount of the previous period), and the reserved retention amounts are reserved for specific multimedia information, for example, p% (first retention ratio) =sum (all retention requirements in the current period, namely, the first multimedia information amount of fine ranking)/total yesterday exposure amount. Then, the multimedia information melon requiring the amount of the reservation in all the amount-reserved sets divides the flow of the% p.
In the embodiment of the present invention, the first maintenance ratio is determined according to the amount of the first multimedia information, and since the first multimedia information is recalled from the individual link by the server based on the preset maintenance configuration information, that is, the amount of the first multimedia information is configured to satisfy the maintenance number, the larger the maintenance number is, the higher the first maintenance ratio is. For each of the sets of metrics, the flow of% p is divided according to the internal duty ratio after the internal duty ratio of each is determined.
In some embodiments of the present invention, the server may be in a CTR manner according to a preset screening rule, and each of the quality-preserving sets may determine, according to the level of the CTR, the amount of information that may be selected by the specific multimedia information in each of the quality-preserving sets in the first amount of multimedia information.
It should be noted that, in the embodiment of the present invention, each specific implementation of screening may adopt a CTR mode, and the embodiment of the present invention is not limited.
In some embodiments of the present invention, determining, for the server in the second and third modes, an implementation process of the candidate multimedia information set from the fine-ranking candidate multimedia information set according to a second preset screening threshold, includes: the server determines a second conservation duty ratio from the fine-ranking candidate multimedia information set through an independent link; the second conservation duty ratio represents the proportion of the first sub-multimedia information of the fine-ranking candidate multimedia information set to the first multimedia information; determining the number of the multimedia information corresponding to the candidate multimedia information set based on the fine-ranking candidate multimedia information set and a second preset screening threshold; determining the first multimedia information amount based on the second conservation duty cycle; selecting first sub-multimedia information of a first multimedia information quantity from the fine candidate multimedia information set, and selecting second sub-selected multimedia information from the fine candidate multimedia information set according to the multimedia information quantity; the second sub-multimedia information is a subset of the fine-ranked second multimedia information in the fine-ranked candidate multimedia information set; the first sub-multimedia information and the second sub-candidate multimedia information are used as candidate multimedia information sets.
The second preset screening threshold is the number of the multimedia information entering the mixed discharging stage in the fine discharging stage, and the value of the second preset screening threshold is preset, which is not limited in the embodiment of the invention.
In the embodiment of the present invention, the server may select the first multimedia information by mixing the amount occupying the sum of the second retention amounts to the next stage, but the amount of mixed multimedia information reaching the second preset screening threshold value for entering the mixed stage must not be enough, so that the second sub-multimedia information for supplementing the second preset screening threshold value is selected from the fine candidate multimedia information set according to the amount of the multimedia information to enter the information processing of the mixed stage. The amount of multimedia information here is the same value as the second preset screening threshold.
Here, the server needs to select the candidate multimedia information of the second preset screening threshold from the fine-ranked candidate multimedia information, and thus, the number of multimedia information of the candidate multimedia information is the second preset screening threshold.
Further, for the fine-ranking first multimedia information, the process of selecting the first sub-multimedia information with the second conservation duty ratio is as follows: the server firstly determines the number of first sub-multimedia information based on the total number of the preset multimedia information and the second conservation duty ratio, then selects the first sub-multimedia information of the number of the first sub-multimedia information from the precisely-arranged first multimedia information according to a preset screening rule, and selects the second sub-multimedia information from the precisely-arranged candidate multimedia information set according to the number of the multimedia information; the second sub-multimedia information is a subset of the fine-ranked second multimedia information in the fine-ranked candidate multimedia information set; and finally, the server takes the first sub-multimedia information and the second sub-multimedia information together as a candidate multimedia information set, and enters the information processing of the mixed arrangement stage.
In the embodiment of the present invention, since the fine-ranked first multimedia information may belong to multiple quality-preserving sets, the server may determine, for each quality-preserving set, a specific multimedia number (corresponding to the first sub-multimedia information number of each quality-preserving set) of mixed-ranked of each quality-preserving set, and prioritize the fine-ranked first multimedia information in the quality-preserving set with a small quality-preserving number.
In some embodiments of the present invention, for fine-ranking first multimedia information in each of the alert sets, obtaining a number of alerts corresponding to each of the alert sets from preset alert configuration information, determining a second alert duty corresponding to each of the alert sets based on a sum of the alert data and the number of alerts of all of the alert sets, and then determining the actual reserved quantity of the reserved quantity in each quantity of the reserved sets based on the quantity of the multimedia information and the second quantity of the reserved quantity, wherein the actual reserved quantity of the reserved quantities is at least 1, so that part of the first sub-multimedia information in each quantity of the reserved sets can be determined according to the actual reserved quantity of the reserved quantities, and the first sub-multimedia information is obtained.
Illustratively, since the fine-pitch stage also cannot determine the final exposure, only the guaranteed amount of the first sub-multimedia information can appear in the mixed candidate set. Thus, if the quality-preserving individual link in the fine-ordering stage has a value of Quote (second preset filtering threshold, i.e. the number of pieces of multimedia information) of P, the selection of the P pieces of first sub-multimedia information can be determined simply using the second quality-preserving ratio of the quality-preserving number, assuming K (K) <P) sets of guarantees, each set of guarantees (i-th set of guarantees) requiring a number of guarantees of N i (preset amount of protection configuration information), the total number of guarantees (sum of the number of guarantees of all the sets of guarantees) isEach of the sets of measures actual reserved quantity number->Wherein Q is preferentially calculated as the number of the guarantees is smaller i 。/>
In S105, the server may determine the exposed multimedia information satisfying each of the exposed bits in the current page from the candidate multimedia information set.
It should be noted that, in the embodiment of the present invention, the selection process and implementation principle of the exposure multimedia information of each exposure bit requested by the server in the exposure request are the same, and are all selected from the candidate multimedia information. The specific implementation can be that the server can determine the exposure multimedia information corresponding to each exposure bit according to the height of the CTR for each quality-preserving set in a CTR mode according to a preset screening rule. The embodiments of the present invention may also be implemented in other manners, and will be described in detail in the following embodiments.
In S106 and S107, after the server selects the exposure multimedia information corresponding to each exposure bit of the current page, the server may push the exposure multimedia information to the terminal, and then the terminal displays the exposure multimedia information corresponding to each exposure bit in the current page, so as to implement exposure.
It can be understood that the server can implement reservation of the specific multimedia information, that is, reservation of the first retention ratio and/or the second retention ratio, through separate links in the coarse-row and/or fine-row stages, so that the specific multimedia information entering the mixed row is guaranteed by a certain proportion, enough retention information in the specific multimedia information can be exposed, and the exposure of the specific multimedia information is improved.
In some embodiments of the present invention, based on fig. 3, fig. 5 is an optional flowchart of a multimedia information recommendation method provided in the embodiment of the present invention, and implementation of S105 may include: s1051 and S1052 will be described in connection with the steps shown in fig. 3.
S1051, the previous period of the reserve supply amount and the current reserve supply amount are acquired.
S1052, based on the previous period of the reserve supply amount, the current reserve supply amount and the preset reserve configuration information, the exposed multimedia information is determined from the candidate set of multimedia information.
In the embodiment of the invention, the server can acquire the amount of the reserved amount in the previous period, namely, the total amount of the actually supplied first multimedia information in the previous period, and can also acquire the current amount of the reserved amount in the current period, namely, the exposure amount of the first multimedia information which is already finished at the current time. Thus, the server can determine the exposed multimedia information from the candidate multimedia information set based on the previous period of the reserve supply amount, the current reserve supply amount, and the preset reserve configuration information.
Wherein the current reserve supply is obtained online in real time.
In some embodiments of the present invention, in a shuffling stage, the exposure multimedia information corresponding to each exposure bit is screened out for exposure, where the acquisition of the exposure multimedia information corresponding to each exposure bit is implemented by using an improved online HWM algorithm, an allocation order and an occurrence probability (service rate) of the first sub-multimedia information are required to be determined for a candidate multimedia information set, the first exposure multimedia information which is finally retained is determined based on the allocation order and the occurrence probability (service rate), and then, second exposure multimedia information corresponding to the second sub-multimedia information is determined from the candidate multimedia information set; the first exposure multimedia information and the second exposure multimedia information are used as exposure multimedia information.
In some embodiments of the present invention, the server obtains the previous period of the reserve supply and the current reserve supply; determining the distribution sequence and the service rate of a corresponding first sub-multimedia information set in the candidate multimedia information set based on the amount of the reserved amount supply in the last period, the current reserved amount supply and the preset reserved amount configuration information; the method comprises the steps of collecting first sub-multimedia information into a collection composed of the first sub-multimedia information; determining first exposure multimedia information from the first sub-multimedia information set based on the allocation order and the service rate; determining second exposure multimedia information corresponding to the second sub multimedia information from the candidate multimedia information set; the second sub-multimedia information is a subset of the fine-ranked second multimedia information in the fine-ranked candidate multimedia information set; the first exposure multimedia information and the second exposure multimedia information are used as exposure multimedia information.
In some embodiments of the present invention, the server determines, based on the previous period of the reserve supply amount, the current reserve supply amount, and the preset reserve configuration information, the allocation order and the service rate of the corresponding first sub-multimedia information set in the candidate multimedia information set as follows: the server determines the distribution sequence of each first sub-multimedia information set in the candidate multimedia information set based on the ratio of the reserve supply quantity of the previous period and the preset reserve configuration information; acquiring a current guarantee duty ratio at the current moment, and determining the residual supply quantity at the current moment based on the current guarantee duty ratio and the guarantee supply quantity of the previous period; and obtaining the service rate of each first sub-multimedia information set based on the current guarantee supply amount, the preset guarantee configuration information, the residual supply amount at the current moment, the guarantee supply amount of the last period and the preset service rate model.
In the embodiment of the present invention, the server needs to count the amount of the reserve in each reserve set in the previous period, then determine, for each reserve set (corresponding to each candidate multimedia information subset, i.e., one set of candidate multimedia information), a ratio of the amount of the reserve in the previous period to the preset amount of the reserve configuration information, and then determine, based on the size of the ratio of each reserve set, an allocation order of each reserve set, where a smaller ratio indicates a higher degree of urgency, and preferentially allocates traffic. The server calculates the current reserve duty at the current time on line for each reserve set, and thus calculates the remaining supply at the current time, that is, the remaining supply=the reserve supply of the previous cycle (1-current reserve duty). The server can then obtain a service rate for each of the sets of the guaranty (each of the candidate subsets of the multimedia information) based on the current guaranty supply, the preset guaranty configuration information, the remaining supply at the current time, the guaranty supply of the last period, and the preset service rate model.
Exemplary, in the embodiment of the present invention, it is assumed that the reserve supply amount of the previous cycle is s i This s i For the number of each insurance set i of the feasible insurance candidate set stage, presetting the number of required insurance of each insurance set j corresponding to the insurance configuration information as d j . Then, for a guaranteed set j, the corresponding service rate is α j 。
In the embodiment of the invention, because the flow difference is relatively large at different moments, the uniform flow can be assumed to be in direct proportion to the flow as much as possible for the guaranteed amount at each moment, namely the number of the guaranteed amounts is relatively larger when the flow is large, and the number of the guaranteed amounts is smaller when the flow is small. For Feed flows, the daily flow distribution is relatively regular, and taking the granularity of minutes as an example, the flow ratio at each moment (for example, per minute) can be counted, i.e. the current conservation ratio is set to be t. For each of the guard sets, if the guard completion number duty ratio at the current time exceeds the flow duty ratio at the current time, the degree of homogeneity is considered to be destroyed, and the candidate set is not used. Then, for all i, the residual flow r i ＝s i *(1-t)。
It can be understood that based on the consideration of the current conservation duty ratio, the uniform setting of the conservation is realized, and the effect of uniform conservation of the moment level can be realized in the current period.
Here, the preset service rate model characterizes a correspondence relationship between a current reserve supply amount, preset reserve configuration information, a remaining supply amount at a current time, and a reserve supply amount and a service rate in a previous period. As in formula (1):
∑ i∈Γ(j) min{r i ，s i α j }＝d j -c j (1)
that is, the server calculates the service rate α online j In time, the real-time count c of the guaranteed quantity can be obtained in real time or near real time j (current amount of credit supplied) so that determining the service rate of the particular multimedia information in each credit set that is subsequently also in need of credit is based on the actual demand for the further needed credit (i.e., d j -c j ) To solve for.
It can be understood that in the process of preserving the quantity, the condition that the preserving quantity is completed is considered, so that the solution of the service rate is more accurate, the exposure degree of the specific multimedia information to be exposed can be fully ensured, and the exposure rate of the specific multimedia information (first multimedia information) is improved.
It should be noted that, the service rate of each of the guaranty sets needs to be solved, and it needs to be guaranteed that the service rate of each of the guaranty sets is at least 1, that is, when equation (1) has no solution, α is set j ＝1。
In some embodiments of the present invention, after solving the service rate of each of the quality-keeping sets, the server may determine the exposed multimedia information from the candidate multimedia information sets based on the allocation order and the service rate.
That is, the server may determine first exposed multimedia information from the first sub-multimedia information in the candidate multimedia information set based on the allocation order and the service rate, and re-select second exposed multimedia information from the second sub-multimedia information.
In some embodiments of the present invention, the first exposure multimedia information and the second exposure multimedia information may be used as the exposure multimedia information, respectively, and if it is assumed that the exposure bits are specific multimedia information exposure bits and the exposure bits are non-specific exposure multimedia information exposure bits, the first exposure multimedia information or the second exposure multimedia information may be directly used as the exposure multimedia information according to different exposure types of the exposure bits.
For example, for a preset number of exposure bits in the current page, a certain number of specific exposure bits will be reserved for the specific multimedia, and the remainder is common exposure bits, for each specific exposure bit, the first exposure multimedia information in the specific exposure bit may be selected as exposure multimedia information based on the allocation sequence and the service rate, the same principle is adopted to determine all exposure multimedia information of the specific exposure bit, and the second exposure multimedia information is determined, where after the exposure multimedia information corresponding to each common exposure bit, all exposure multimedia information corresponding to all preset number of exposure bits is sent to the terminal, and all exposure multimedia information may be displayed in the current page of the terminal.
In the embodiment of the invention, the corresponding relation between the exposure bits and the exposure multimedia information is not limited in the display process, so long as the type of the exposure bits is consistent with the corresponding quantity of the type of the exposure multimedia information, for example, among 10 exposure bits, 3 exposure bits display 3 final specific multimedia information.
In some embodiments of the present invention, the process of determining the first exposed multimedia information for the server is: determining the arrangement sequence of each first sub-multimedia information set according to the distribution sequence of each first sub-multimedia information set; when the sum H of the service rates of the first j first sub-multimedia information sets of the first sub-multimedia information sets is smaller than 1 based on the arrangement sequence, determining the actual service rate of the j+1th first sub-multimedia information set as 1-H, wherein j is the maximum value that the sum of the service rates of the first j first sub-multimedia information sets is smaller than 1, and the actual service rates of candidate multimedia information sets starting from the j+2th first sub-multimedia information set are all 0; and selecting the first exposure multimedia information from the first j first sub-multimedia information sets according to the service rates of the first j first sub-multimedia information sets.
It should be noted that, in the above embodiment, each candidate multimedia information set mainly refers to each of the quality-preserving sets, so that the server determines the first exposed multimedia information based on the allocation sequence and the service rate of each quality-preserving set.
It should be noted that, in the embodiment of the present invention, exposure of the first sub-multimedia information in the first-order-assigned policy set needs to be preferentially guaranteed, and the sum of the actual service rates of each selected policy set cannot be greater than 1, but the sum of the service rates of each policy set calculated by the server online may be greater than 1, so the server needs to determine the order of each policy set according to the order of the assignment from the sharp to the slow, then keep the actual service rate in the policy set with the sum H of the service rates of the first j first sub-multimedia information sets smaller than 1 as the online calculated service rate, and determine the actual service rate of the j+1th first sub-multimedia information set as 1-H, and then select the first sub-multimedia information in each corresponding policy set with the probability of the final actual service rate.
Illustratively, the server makes the selection of the first exposed multimedia information based on the following policies:
given an exposure, let J= { C 1 ，C 2 ，…，C |J| To satisfy the ad list(s) of the targeting contract, J is ordered in the order of allocation.
If it isLet l be satisfied->Maximum value of condition, finally let->
Thus, at alpha j Is to select a contract j e 1, l](first exposure multimedia information) and at alpha' l+1 If the probability of selecting the l+1 contract advertisement (second exposure multimedia information) is further increasedPossibly l+1 contracted ads are not contracted to be selected.
The server can realize reservation of specific multimedia information through separate links in the coarse arrangement and/or fine arrangement stage, namely, reservation of the first conservation rate and/or the second conservation rate, so that specific multimedia information entering mixed arrangement is guaranteed in a certain proportion, and the uniformity of service rate is guaranteed based on real-time participation of current conservation supply quantity aiming at candidate multimedia information sets, so that on the premise of guaranteeing the conservation proportion and realizing the conservation uniformity, enough conservation information in the specific multimedia information can be exposed, and the exposure of the specific multimedia information is improved.

The first multimedia information is taken as specific multimedia information to carry out schematic description of the embodiment of the invention by adopting a specific refreshing application scene.
Scene one, the amount is preserved in the coarse row stage. When a user opens a news application on a terminal 1 (in a mobile phone for illustration, but not limited to, a mobile phone), as shown in fig. 9A, the terminal 1 displays information 2 of a current page, when the current page receives a refresh operation of the user (for example, a slide operation from a position a to a position B), a refresh request is generated (which may also be understood as an exposure request), the terminal 1 sends the refresh request to a background server 3, the server 3 starts recall, acquires 10000 pieces of multimedia information to be exposed, including 5000 pieces of specific multimedia information, and performs a guarantee process when the server 3 performs coarse-ranking, so that the server 3 calculates a pool (corresponding to a first guarantee ratio) of a reserved guarantee according to a total daily exposure (total exposure of a previous period), and is specially reserved for the specific multimedia information, for example, p% (the first guarantee ratio) =sum (all the guarantee requirements in the current period, i.e., the total number of precisely-ranking first multimedia information)/total daily exposure. Then, the flow of the% p of the multimedia information to be held in all the holding amount sets (first holding ratio) is calculated, assuming that the% p is 10%, that is, the server 3 screens out 10% of 5000 pieces of specific multimedia information, that is, 500 pieces of specific multimedia information as fine-ranking specific candidate multimedia information (fine-ranking first multimedia information), and the server 3, in the coarse ranking stage, needs to screen out the fine-ranking candidate multimedia information sets satisfying the first preset threshold, assuming that the first preset threshold is 2000 pieces, the server 3 already occupies 500 pieces of names with 500 pieces of fine-ranking specific candidate multimedia information, then the server 3 also needs to select 2000-500=1500 pieces of remaining fine-ranking candidate multimedia information (fine-ranking second multimedia information) from 5000 pieces of specific multimedia information to be exposed, out of 10000 pieces of the remaining pieces of specific multimedia information (second multimedia information), then uses 500 pieces of fine-ranking specific multimedia information and 1500 pieces of fine-ranking candidate multimedia as fine-ranking candidate multimedia to enter the second pre-ranking stage, and performs the pre-processing on the assumption that 500 pieces of fine-ranking candidate multimedia information sets enter the second stage If the screening threshold is 200, the server 3 selects 200 pieces of multimedia information from 2000 pieces of fine candidate multimedia information as candidate multimedia information sets, entering a shuffling stage in which the server 3 counts the amount of the reserve supply in each reserve set in the previous cycle, then for each of the quality-guaranteed sets (corresponding to each of the candidate sub-sets of multimedia information), determining the ratio of the reserve supply quantity of the previous period and the preset reserve configuration information, and then determining the allocation sequence of each of the insurance sets based on the magnitude of the ratio of each of the insurance sets, wherein the smaller the ratio is, the higher the degree of emergency is, and the traffic is allocated preferentially. The server calculates the current reserve duty t at the current time on line for each reserve set, and thus calculates the remaining supply at the current time, that is, the remaining supply=the reserve supply of the previous cycle (1-current reserve duty). The server can then obtain a service rate for each of the sets of the guaranty (each of the candidate subsets of the multimedia information) based on the current guaranty supply, the preset guaranty configuration information, the remaining supply at the current time, the guaranty supply of the last period, and the preset service rate model.

Then, for a guaranteed set j, the corresponding service rate is α j And for all i, the residual flow r i ＝s i * (1-t). Here, the server calculates the service rate α online j In time, the real-time count c of the guaranteed quantity can be obtained in real time or near real time j Whereby determining the service rate of the first sub-multimedia information in each of the subsequent sets of the required maintenance is based on the actual requirements of the required maintenance (i.e. d j -c j ) To solve for. After the server solves for the service rate of each of the quality-of-service sets, the server can then base the allocation order and the service rate α j Determining a first exposed multimedia information from the candidate multimedia information set and a second exposed multimedia from the second sub-multimedia informationThe media information, the first exposed multimedia information and the second exposed multimedia information constitute exposed multimedia information. Assume that the allocation order and the service rate alpha are based j When selecting one exposure bit 4 (the exposure bit reserved for the specific multimedia information) for the current page, the server 3 screens the first exposure multimedia information of the exposure bit 4 from 200 candidate multimedia information according to the allocation sequence and according to the service rate alpha j Determining the probability of the first sub-multimedia information appearing in the exposure bit 4, selecting the second exposure multimedia information exposed by the exposure bit 4 according to the probability, finding the exposure multimedia information of all the exposure bits based on the second exposure multimedia information, transmitting the exposure multimedia information to the terminal 1, and displaying the exposure multimedia information on the exposure bit of the terminal 1.

In the shuffling stage, the server 3 counts the amount of the reserve supply in each reserve set in the previous period, then determines, for each reserve set (corresponding to each candidate multimedia information subset), a ratio of the amount of the reserve supply in the previous period to the preset amount of the reserve configuration information, and then determines an allocation order of each reserve set based on the magnitude of the ratio of each reserve set, wherein a smaller ratio indicates a higher degree of urgency, and preferentially allocates traffic. The server calculates the current reserve duty t at the current time on line for each reserve set, and thus calculates the remaining supply at the current time, that is, the remaining supply=the reserve supply of the previous cycle (1-current reserve duty). The server can then obtain a service rate for each of the sets of the guaranty (each of the candidate subsets of the multimedia information) based on the current guaranty supply, the preset guaranty configuration information, the remaining supply at the current time, the guaranty supply of the last period, and the preset service rate model. Based on this, the server in the embodiment of the present invention may assume that the reserve supply amount in the last period is s i This s i For the number of each insurance set i of the feasible insurance candidate set stage, presetting the number of required insurance of each insurance set j corresponding to the insurance configuration information as d j . Then, for a guaranteed set j, the corresponding service rate is α j And for all i, the residual flow r i ＝s i * (1-t). Here, the server calculates the service rate α online j In time, the real-time count c of the guaranteed quantity can be obtained in real time or near real time j Whereby determining the service rate of the first sub-multimedia information in each of the subsequent sets of the required maintenance is based on the actual requirements of the required maintenance (i.e. d j -c j ) To solve for. After the server solves for the service rate of each of the quality-of-service sets, the server can then base the allocation order and the service rate α j Determining first exposure multimedia information from the candidate multimedia information set, and determining second exposure multimedia information from the second sub-multimedia information, the first exposure multimedia information and the second exposure multimediaThe volume information constitutes the exposed multimedia information. Assume that the allocation order and the service rate alpha are based j When selecting one exposure bit 4 (the exposure bit reserved for the specific multimedia information) for the current page, the server 3 screens the first exposure multimedia information of the exposure bit 4 from 200 candidate multimedia information according to the allocation sequence and according to the service rate alpha j Determining the probability of the first sub-multimedia information appearing in the exposure bit 4, selecting the second exposure multimedia information exposed by the exposure bit 4 according to the probability, finding the exposure multimedia information of all the exposure bits based on the second exposure multimedia information, transmitting the exposure multimedia information to the terminal 1, and displaying the exposure multimedia information on the exposure bit of the terminal 1.

And in a third scene, the amount is simultaneously ensured in a coarse discharge stage and a fine discharge stage. When a user opens a news application on the terminal 1, as shown in fig. 9C, the terminal 1 displays information 2 of a current page, when the current page receives a refresh operation (for example, a slide operation from a position a to a position B) of the user, a refresh request (also can be understood as an exposure request) is generated, the terminal 1 sends the refresh request to the background server 3, the server 3 starts to recall to obtain 10000 pieces of multimedia information to be exposed, wherein 5000 pieces of specific multimedia information are contained, the server 3 performs one-time guarantee processing when performing coarse arrangement, and then the server 3 calculates a pool (corresponding to a first guarantee ratio) of reserved guarantees according to the total yesterday exposure (total exposure of the last period), and is specially reserved for the specific multimedia information to be applied, for example, p% (first guarantee ratio) =sum (all guarantee requirements in the current period, namely, the total number of precisely arranged first multimedia information)/total daily exposure. Then, the multimedia information needed to be protected in all the protected sets is divided into the flow of the% p (first protected ratio), let% p be 10%, that is, the server 3 screens out 10% of 5000 pieces of specific multimedia information, that is, 500 pieces of specific multimedia information are used as fine-ranking specific candidate multimedia information, and the server 3, in the coarse ranking stage, needs to screen out a fine-ranking candidate multimedia information set meeting a first preset threshold, assuming that the first preset threshold is 2000 pieces, the server 3 already occupies 500 pieces of names with 500 pieces of fine-ranking specific candidate multimedia information, so that the server 3 also needs to select 2000-500=1500 pieces of residual fine-ranking candidate multimedia information from 10000 pieces of to-be-exposed multimedia information except 5000 pieces of specific multimedia information, then uses 500 pieces of fine-ranking specific candidate multimedia information and 1500 pieces of residual fine-ranking candidate multimedia as fine-ranking candidate multimedia information sets, performs information processing in the fine ranking stage, and if the second preset screening threshold is 200 pieces of fine-ranking candidate multimedia information (wherein, the number of fine-ranking first multimedia information is 500 pieces), and the second preset screening threshold is 100 pieces of fine-ranking candidate multimedia information from the first candidate multimedia information to the fine ranking candidate multimedia information set, and the second preset screening threshold is 100 pieces of fine-ranking candidate multimedia information, and the fine-ranking candidate multimedia information sets are mixed with the second candidate multimedia information sets, and the fine-ranking candidate multimedia information sets is selected from 100 pieces.

The server calculates the current reserve duty t at the current time on line for each reserve set, and thus calculates the remaining supply at the current time, that is, the remaining supply=the reserve supply of the previous cycle (1-current reserve duty). The server can obtain the service rate of each guarantee set based on the current guarantee supply amount, the preset guarantee configuration information, the residual supply amount at the current moment, the guarantee supply amount of the last period and the preset service rate model. Assume that the previous period of the reserve supply quantity Is s i This s i For the number of each insurance set i of the feasible insurance candidate set stage, presetting the number of required insurance of each insurance set j corresponding to the insurance configuration information as d j . Then, for a guaranteed set j, the corresponding service rate is α j And for all i, the residual flow r i ＝s i * (1-t). Here, the server calculates the service rate α online j In time, the real-time count c of the guaranteed quantity can be obtained in real time or near real time j Whereby determining the service rate of the first sub-multimedia information in each of the subsequent sets of the required maintenance is based on the actual requirements of the required maintenance (i.e. d j -c j ) To solve for.
