Referring to fig. 1, fig. 1 is an application scenario schematic diagram of an advertisement delivery method based on a bloom filter according to an embodiment of the present application. The bloom filter-based advertisement delivery method is applied to the advertisement delivery system in fig. 1, and the advertisement delivery system includes an advertisement delivery platform 10 provided in the present application and a requester 20 for advertisement delivery (such as messenger, hundred degrees, tremble, etc.), where bloom filters corresponding to each policy result in at least one policy result are preset in the advertisement delivery platform 10, and a plurality of corresponding device identifiers are stored in each bloom filter: when the user opens the application corresponding to the requester 20 in the target device (device corresponding to the target device identifier), the requester 20 will send an advertisement delivery request carrying the target device identifier to the advertisement delivery platform 10, and then the advertisement delivery platform 10 determines which bloom filters the target device identifier hits, and returns a target policy result corresponding to the hitting bloom filter to the requester 20.
It should be noted that, before executing the advertisement delivery method based on the bloom filter provided in this embodiment, a plurality of bloom filters need to be created according to a preset policy rule of advertisement delivery, where each bloom filter stores a device identifier that conforms to a corresponding policy rule, that is, each bloom filter corresponds to a policy result, and when a received device identifier also exists in a bloom filter, it is illustrated that the policy result corresponding to the bloom filter is the policy result that needs to be returned, and specifically, steps of creating the bloom filter by the advertisement delivery platform are shown in fig. 2, and specifically include steps S110 to S140:
S110, reading the equipment identification file according to a preset file acquisition path.
The device identifier file includes a plurality of device identifiers and scoring results of a plurality of scoring sources corresponding to the device identifiers respectively, and specifically, the embodiment reads the device identifier file by using a mmap memory mapping mode based on the file acquisition path.
The equipment identifier is an equipment identifier corresponding to user equipment (such as a mobile phone), such as an IMEI, an OAID, an IDFA of an IOS and the like of Android, wherein scoring sources comprise company interiors, allies, temming, talkingdata and the like, and scoring results comprise, but are not limited to, click scores, completion scores, credit passing scores, current scores, overdue scores, credit quality scores and click credit passing scores.
Specifically, in some embodiments, the scoring results are determined from their corresponding big data models, e.g., device id 1 is rated at 0.7 and 0.8 points, respectively, and the completion points are rated at 0.5 and 0.6, respectively, relative to the different scoring sources (e.g., messenger and alliance).
The preset file acquisition path is a path capable of acquiring an equipment identification file, for example, a uniform resource locator (Uniform Resource Locator, URL) path, and the equipment identification file may be stored in a cloud storage and other locations, and the specific type of the file acquisition path and the specific storage location of the equipment identification file are not limited in this embodiment.
In some embodiments, in order to improve the security of the device identification file, the obtained device identification file is an encrypted device identification file, for example, an encrypted device identification file subjected to MD5 (an information abstraction algorithm), so as to prevent the device identification file from being tampered, which affects the accuracy of the final result.
S120, creating a plurality of bloom filters according to a plurality of preset strategy rules, and building a corresponding relation between each bloom filter and a strategy result.
In this embodiment, specifically, bloom filters are created according to the number of policy rules, for example, if there are 15 policy rules, then 15 bloom filters are created, where the policy result is a policy result corresponding to the policy rules, specifically, in this embodiment, policy results corresponding to the policy rules are preset respectively, and after bloom filters corresponding to the policy rules are created, a correspondence between the bloom filters and the policy results is established according to a correspondence between the policy rules and the policy results.
In some embodiments, before executing step S120, a plurality of policy rules and policy results corresponding to the policy rules respectively need to be obtained, where a bloom filter is required to be created for one policy rule later, and the policy result corresponding to the bloom filter is the policy result corresponding to the policy rule.
In this embodiment, a user first needs to preset a plurality of policy rules (an advertisement policy generally includes 2 or 3 policy rules) in the advertisement delivery platform, for example, an advertisement policy a includes a policy rule 1a and a policy rule 2a, and an advertisement policy b includes a policy rule 1b and a policy rule 2b, where:
advertisement strategy a:
policy rule 1a (corresponding to creating bloom filter 1 a): t1<0.8; the corresponding strategy results are: not exposing;
policy rules 2a (corresponding to creation of bloom filter 2 a): t1> =0.8 and t2>0.6 and t3>0.7; the corresponding strategy results are: exposing and bidding for 1.5 times;
advertisement policy b:
policy rule 1b (corresponding to creating bloom filter 1 b): u1<0.2; the corresponding strategy results are: not exposing;
policy rules 2b (corresponding to creating bloom filter 2 b): u1> =0.2 and u2>0.5 and u3>0.7; the corresponding strategy results are: exposure, and bid 1.2 times.
Wherein t1, t2 and t3 are respectively click score, completion score and credit passing score of vacation (scoring source) aiming at a certain equipment identifier; u1, u2 and u3 are respectively the click score, the completion score and the credit passing score of the alliance (scoring source) aiming at a certain equipment identifier;
therefore, if the policy rules include the policy rule 1a, the policy rule 2a, the policy rule 1b, and the policy rule 2b, it is necessary to construct the bloom filter 1a, the bloom filter 2a, the bloom filter 1b, and the bloom filter 2b for these policy rules, respectively, and the policy result corresponding to the bloom filter 1a is not exposure; the corresponding policy result of bloom filter 2a is exposure and bid 1.5 times; the corresponding policy result of bloom filter 1b is exposure; the corresponding policy result for bloom filter 2b is exposure and bid 1.2 times.
The execution order of the step S110 and the step S120 is not limited in this application, that is, the step S110 may be executed after the step S120, or may be executed simultaneously with the step S120.
S130, respectively storing the equipment identifiers into the corresponding bloom filters according to a plurality of scoring results and the policy rules respectively corresponding to the equipment identifiers.
In this embodiment, the device identifier file includes a plurality of device identifiers, and scoring results of a plurality of scoring sources corresponding to the device identifiers respectively.
Specifically, for each device identifier in the device identifier file, determining a policy rule which is met by the device identifier according to a plurality of scoring results (a plurality of scoring results of different scoring sources) of the corresponding device identifier, and writing the device identifier into a corresponding bloom filter (bloom filter hit with the policy rule), wherein if the device identifier meets a plurality of policy rules, the device identifier is written into a corresponding plurality of bloom filters.
For example, the device identifier 1 corresponds to a plurality of scoring results t1=0.9, t2=0.8, t3=0.8, u1=0.1; as can be seen from the above policy rules, the scoring result of the device identifier 1 accords with the policy rule 2a and the policy rule 1b, and the policy rule 2a corresponds to the Ying Bulong filter 2a and the policy rule 1b corresponds to the Ying Bulong filter 1b, and at this time, the device identifier 1 is written into the bloom filter 2a and the bloom filter 1b, respectively.
And S140, storing a plurality of bloom filters.
After traversing all the device identifications in the device identification file and writing the corresponding device identifications into the corresponding bloom filter, storing the bloom filter.
Therefore, the advertisement delivery platform provided by the application does not need to store the equipment identification file, and only needs to store different equipment identifications into the corresponding bloom filters according to the corresponding strategy results, so that the storage amount of data in the advertisement delivery platform is greatly reduced, and storage resources are saved.
Fig. 3 is a flowchart of an advertisement delivery method based on a bloom filter according to an embodiment of the present application. The method is applied to an advertisement delivery platform, a bloom filter corresponding to each policy result in at least one policy result is preset in the advertisement delivery platform, and a plurality of corresponding device identifiers are stored in each bloom filter, as shown in fig. 3, and the method comprises the following steps S210-S240.
S210, receiving an advertisement putting request sent by a requester, wherein the advertisement putting request comprises a target device identifier.
In this embodiment, when a requester (such as a messenger, hundred degrees, and jittering applications) of advertisement delivery needs to request a RTA (Realtime API) service of the advertisement delivery platform, an advertisement delivery request is sent to the advertisement delivery platform, where the advertisement delivery request includes a target device identifier, and the target device identifier is encrypted by MD 5.
Specifically, when a user uses a target device (such as a mobile phone) to brush and shake sound, the shake sound background generates an advertisement putting request according to a target device identifier of the target device, and sends the advertisement putting request to an advertisement putting platform.
S220, responding to the advertisement putting request, determining the bloom filters with the target equipment identifiers as target bloom filters, and obtaining at least one target bloom filter.
When the advertisement delivery platform acquires the advertisement delivery request, judging which bloom filters in a plurality of bloom filters in the local area of the advertisement delivery platform store the target equipment identifier, and determining the bloom filter storing the target equipment identifier as a target bloom filter, wherein the number of the target bloom filters can be 1 or more, and when the number of the target bloom filters is more than 1, the fact that the target equipment identifier is stored in the plurality of bloom filters is indicated, namely the target equipment identifier accords with a plurality of returned results.
S230, determining a strategy result corresponding to the target bloom filter as a target strategy result.
In some embodiments, specifically, S230 includes: if the strategy results corresponding to the target bloom filter comprise exposure results and non-exposure results, determining the exposure results as the target strategy results; if the strategy result corresponding to the target bloom filter is a non-exposure result, determining the non-exposure result as the target strategy result; and if the strategy result corresponding to the target bloom filter is an exposure result, determining the exposure result as the target strategy result.
For example, if multiple target bloom filters are hit, and the corresponding policy results include an exposure result and a non-exposure (i.e., non-exposure) result, then only the exposure result needs to be returned, i.e., only the exposure result is taken as the target policy result, and the non-exposure result is filtered out; if the corresponding strategy result is a non-exposure result (not including an exposure result), only one non-exposure result is returned no matter one or more non-exposure results are provided, namely, one non-exposure result is determined as a target strategy result; if the corresponding strategy result is an exposure result (not including a non-exposure result), determining the exposure result as a target strategy result according to the exposure result;
further, when there are a plurality of exposure results, at this time, according to determining the exposure result as a target policy result, it includes:
a. determining an exposure result with the highest priority among a plurality of exposure results as the target strategy result according to the preset priority; or b, determining a plurality of exposure results as the target strategy results.
The step a is adopted to reduce the data volume transmitted by the advertisement delivery platform and reduce the calculated volume of a requester; the step b is adopted, so that a requester can obtain more information, and bidding accuracy is improved.
S240, returning the target strategy result to the requester.
In this embodiment, after the advertisement delivery platform determines the target policy result, the target policy result is returned to the requester, so that the requester decides whether to deliver the advertisement corresponding to the advertisement delivery platform according to the obtained target policy result.
In general, a requester sends an advertisement delivery request to advertisement delivery platforms of multiple advertisers, and then receives policy results returned by each advertisement delivery platform, and decides which advertiser's advertisement is delivered according to each policy result.
In some embodiments, after the bloom filter is established, due to the fact that some rules of the bloom filter are invalidated, in order to save storage space and ensure accuracy of policy judgment, the invalidated bloom filter needs to be deleted, for example, the bloom filter to be deleted is a first bloom filter, at this time, a deletion instruction of the first bloom filter input by a user is acquired, and then the first bloom filter in the advertisement delivery platform is deleted in response to the deletion instruction.
In some embodiments, by the application, a bloom filter in the advertisement delivery platform may be newly added, for example, a bloom filter that needs to be newly added is a second bloom filter, and at this time, a new instruction of the second bloom filter needs to be acquired, where the new instruction carries a new policy rule and a new policy result corresponding to the new policy rule; then, the second bloom filter is established according to the new instruction, and a corresponding relation between the second bloom filter and the new strategy result is established; reading a device identification file according to a preset file acquisition path, wherein the device identification file comprises a plurality of device identifications and scoring results of a plurality of scoring sources corresponding to the device identifications respectively; and finally, storing the equipment identifier conforming to the new strategy rule in the equipment identifier file into the second bloom filter, and storing the second bloom filter to finish the new operation of the second bloom filter.
In some embodiments, since there is a relatively large total amount of outdated device identifications and newly added device identifications, to ensure accuracy of the data in the advertising platform, the advertising platform may update the local bloom filter, specifically, periodically or manually: acquiring a bloom filter update instruction; then responding to the bloom filter updating instruction, and reading a device identification file according to a preset file acquisition path, wherein the device identification file comprises a plurality of device identifications and scoring results of a plurality of scoring sources respectively corresponding to the device identifications; and finally, updating the equipment identifiers in the bloom filters according to a plurality of scoring results corresponding to the equipment identifiers and policy rules corresponding to the bloom filters.
Specifically, if the device identifier which accords with the policy rule but does not exist in the bloom filter exists in the device identifier file according to the read device identifier file and the policy rule corresponding to the bloom filter, the device identifier is newly added in the bloom filter; if the bloom filter is found to have the equipment identifier which does not accord with the policy rule or the bloom filter is found to have the equipment identifier which does not exist in the equipment identifier file, deleting the equipment identifier.
The bloom filter update instruction may be automatically generated according to a preset update period (for example, 1 month) in the advertisement delivery platform, or may be input by a user, which is not limited herein.
In summary, the method is applied to an advertisement delivery platform, and at least one bloom filter corresponding to each policy result in the policy results is preset in the advertisement delivery platform, and a plurality of corresponding device identifiers are stored in each bloom filter, and the method includes: receiving an advertisement putting request sent by a requester, wherein the advertisement putting request comprises a target equipment identifier; responding to the advertisement putting request, determining the bloom filters with the target equipment identifiers as target bloom filters, and obtaining at least one target bloom filter; determining a strategy result corresponding to the target bloom filter as a target strategy result; and returning the target strategy result to the requester. On one hand, in the embodiment, the device identifiers corresponding to the different strategy results are stored in different bloom filters in the advertisement delivery platform in advance, so that scoring results of a plurality of scoring sources corresponding to the device identifiers are not required to be stored in the advertisement delivery platform, the storage amount of data in the advertisement delivery platform is greatly reduced, and storage resources are saved; on the other hand, the method and the device can obtain the strategy result directly according to the equipment identifier stored in the bloom filter, and do not need to further calculate according to the scoring result corresponding to the equipment identifier when deciding, so that the response speed of the advertisement delivery platform is improved.
In addition, the bloom filter in the embodiment stores the device identifier in a binary manner, so that the storage amount of data is further reduced.
