Specifically, it may include but is not limited to the landing page URL (Uniform Resource Locator) and additional information, etc.

[0076] Optionally, in this embodiment, the to-be-published content of the media resource is used to represent specific information displayed by the media resource to the user, and the to-be-published location of the media resource is used to represent a specific location displayed by the media resource to the user.

[0077] Optionally, in this embodiment, the above-mentioned splitting of media content into a first group of media elements and splitting of page information into a second group of media elements may include but is not limited to splitting media content into different types of first group media elements and splitting page information into different types of second group media elements. For example, taking the media resource as an advertisement, the above-mentioned media content is the advertising creativity, then the first group of media elements may include but is not limited to videos, advertising slogans, and covers, and the above-mentioned page information is UNIT, which may include but is not limited to landing page URL (Uniform Resource Locator) and additional information.

[0078] Optionally, in this embodiment, the above-mentioned review of each media element in the first group of media elements and each media element in the second group of media elements may include but is not limited to reviewing each media element in the first group of media elements and reviewing each media element in the second group of media elements respectively. The above-mentioned target review result may include but is not limited to review passed or review failed, that is, indicating whether the to-be-published content is allowed to be published in the to-be-published location.

[0079] For example, taking the media resource as an advertisement, the above media content is the advertising creativity, then the first group of media elements may include but not be limited to videos, advertising slogans, and covers, and the above page information is UNIT, which may include but not be limited to the landing page URL (Uniform Resource Locator) and additional information.

[0080] Then, each media element in the first group of media elements and each media element in the second group of media elements are reviewed separately, that is, the video, advertising slogan, and cover in the advertising creativity are reviewed separately, and the landing page URL (Uniform Resource Locator) and additional information in UNIT are reviewed separately. The review results of each element are summarized to obtain the above-mentioned target review results.

[0081] It should be noted that the aggregation method may include but is not limited to determining the above-mentioned target audit result as passed when the audit results of each element indicate passed, and determining the above-mentioned target audit result as failed when the audit result of any element indicates failed.

[0082] Figure 3is a schematic diagram showing a method for reviewing media resources according to an exemplary embodiment. Figure 3 As shown, it can include but is not limited to splitting the media content into a first group of media elements (element 1, element 2, element 3), splitting the page information into a second group of media elements (element A, element B), and reviewing them separately, and finally determining the review result of the media resource to be reviewed based on the review result of each media element.

[0083] The above is only an example, and this embodiment does not impose any specific limitation.

[0084] Through this embodiment, by obtaining the media resources to be reviewed uploaded by the target account, the media content is split into a first group of media elements according to the review type, and the page information is split into a second group of media elements, wherein a media element in the first group of media elements represents an audit unit for reviewing the media content, and a media element in the second group of media elements represents an audit unit for reviewing the page information. The audit type includes the review of the media content and the review of the page information. Each media element in the first group of media elements and each media element in the second group of media elements are reviewed separately to determine the target audit result of the media resources to be reviewed. Therefore, in the process of reviewing the media resources, the media content and page information in the media resources are pre-split into two different groups of media elements, and each media element is reviewed separately in the review stage to determine the audit result of the media resources to be reviewed, thereby improving the review efficiency of the media resources, improving the review quality, reducing the review omission rate, and solving the technical problem of low review efficiency of media resources in related technologies.

[0085] As an optional solution, reviewing each media element in the first group of media elements and each media element in the second group of media elements separately to determine a target review result of the media resource to be reviewed includes:

[0086] Obtaining historical audit results of the target account, wherein the historical audit results are used to indicate audit results of media resources previously uploaded by the target account, and the historical audit results include audit results of media elements having the same identifier as the first group of media elements and the second group of media elements;

[0087] Determining, based on the historical review results, a first review result for each media element in the first group of media elements and a second review result for each media element in the second group of media elements;

[0088] A target review result of the media resource to be reviewed is determined according to the first review result and the second review result.

[0089] Optionally, in this embodiment, the above-mentioned historical audit results may include but are not limited to being recorded in the form of a hash table, wherein each hash value in the hash table represents the audit result corresponding to the MD5 code of a media element, and the audit results of the media resources previously uploaded by the above-mentioned target account may include but are not limited to the audit results of each media element in the media resources previously uploaded by the target account.

[0090] Optionally, in this embodiment, the above-mentioned determination of the audit results of each media element in the first group of media elements based on the historical audit results may include but is not limited to obtaining the MD5 code of each media element, and searching for the audit result corresponding to the same MD5 code from the hash table corresponding to the historical audit results based on the MD5 code; if the MD5 code does not exist in the hash table, the media element without the corresponding MD5 code is placed in the pending audit pool for subsequent audit operations.

[0091] Optionally, in this embodiment, the above-mentioned determination of the target review result of the media resource to be reviewed based on the review results of each media element in the first group of media elements may include but is not limited to determining the target review result of the media resource to be reviewed based only on the review results of each media element in the first group of media elements, and may also include but is not limited to determining the target review result of the media resource to be reviewed based on the review results of each media element in the second group of media elements when the review results of each media element in the first group of media elements are all passed.

[0092] For example, if the media resource is an advertisement, the above media content is the advertising creative. The first group of media elements may include but is not limited to videos, advertising slogans, and covers. The above page information is UNIT, which may include but is not limited to the landing page URL and additional information.

[0093] When the review results of the video, advertising words, and cover in the advertising creative of the advertisement are passed, the landing page URL and additional information in the UNIT will be reviewed. When the video, advertising words, cover, landing page URL and additional information are all reviewed and passed, the target review result of the media resource to be reviewed is determined to be passed.

[0094] Through the embodiments of the present application, the review results of each media element in the first group of media information and the second group of media information are determined based on the historical review results, avoiding the complex process of manual or machine review of each media information, and automatically reviewing the unreviewed media information based on the historical review records, thereby improving the review efficiency of the media information.

[0095] As an optional solution, reviewing each media element in the first group of media elements and each media element in the second group of media elements separately to determine a target review result of the media resource to be reviewed includes:

[0096] Obtaining a set of historical information identifiers of the target account and a review result corresponding to the set of historical information identifiers;

[0097] The first audit result and the second audit result are respectively determined based on the group of historical information identifiers, the audit results corresponding to the group of historical information identifiers, and the target information identifier, wherein the target information identifier is the information identifier corresponding to the target media element to be audited in the group of historical information identifiers, and the target media element is a media element in the first group of media elements or the second group of media elements.

[0098] Optionally, in this embodiment, the above-mentioned acquisition of a set of historical information identifiers of the target account and the audit results corresponding to the set of historical information identifiers may include but are not limited to acquisition of a set of MD5 codes associated with the target account and the audit results corresponding to the MD5 codes, wherein the above-mentioned MD5 codes are MD5 codes calculated after inputting the media resources into the pre-trained model for recognition, and each MD5 code is used to represent the characteristic information of the media content of the media resource.

[0099] For example, taking the media resource as an advertisement, the above-mentioned media content is the advertising creativity, and the first group of media elements may include but is not limited to videos, advertising slogans, and covers. The above-mentioned MD5 code is used to represent the advertising creativity, that is, the MD5 codes of the video, advertising slogans, and cover under the same advertisement are the same, and the MD5 codes of the videos, advertising slogans, and covers representing the same content in different advertisements are also the same.

[0100] Specifically, Advertisement 1 includes Video 1, Advertising Words 1, and Cover 1; Advertisement 2 includes Video 2, Advertising Words 2, and Cover 2. When the contents of Advertisement 1 and Advertisement 2 are exactly the same, Advertising Words 1, Cover 1, Video 2, Advertising Words 2, and Cover 2 all correspond to the same MD5 code. When the contents of Advertisement 1 and Advertisement 2 are not exactly the same, but the contents of Video 1, Advertising Words 1, Video 2, and Advertising Words 2 are the same, and Cover 1 and Cover 2 are different, then Video 1, Advertising Words 1, Video 2, and Advertising Words 2 all correspond to the same MD5 code, while Cover 1 and Cover 2 correspond to different MD5 codes.

[0101] Through the embodiments of the present application, the target media identifier corresponding to the media information to be reviewed is searched from a group of historical information identifiers, and then the corresponding review result is searched through the media identifier, thereby avoiding the complex process of manual or machine review of each media information, and automatically reviewing the unreviewed media information based on the historical review records, thereby improving the review efficiency of the media information.

[0102] As an optional solution, determining the first audit result and the second audit result respectively according to the set of historical information identifiers, the audit results corresponding to the set of historical information identifiers, and the target information identifier includes:

[0103] When the set of historical information identifiers includes a first information identifier that is identical to the target information identifier, determining the audit result corresponding to the first information identifier as the first audit result or the second audit result corresponding to the target media element;

[0104] When the first information identifier is not included in the set of historical information identifiers, the target media element is audited to obtain the first audit result or the second audit result corresponding to the target media element.

[0105] Optionally, in this embodiment, the target information identifier is the MD5 code (Message-Digest Algorithm) corresponding to the target media element in the first group of media elements in the media resource to be reviewed.

[0106] Optionally, in this embodiment, the first information identifier is an information identifier in a group of historical information identifiers, and is an MD5 code determined based on the historical audit results (hash table) of the target account.

[0107] Optionally, in this embodiment, when the first information identifier and the target information identifier are the same, the review result corresponding to the first information identifier is searched for as the review result of the above-mentioned target information identifier; when the first information identifier and the target information identifier are different, the target media element is placed in the pending review pool to continue the subsequent review process (for example, machine review, manual review).

[0108] For example, an advertiser may have multiple accounts, which may create multiple creatives with the same content. Since the MD5 values of media elements with the same content are identical, a hash is generated by aggregating the MD5 and the target account's identifier. This hash uniquely identifies a review unit. If the same creative or unit is modified multiple times and triggers multiple versions to be submitted for review, during the review process and when the review results are sent, if a review is triggered, then for elements with the same content that are still in the pending review pool, they do not need to be inserted into the element review table. Otherwise, they are inserted into the element review table and placed in the pending review pool, awaiting human or machine review.

[0109] Through the embodiments of the present application, when a first media identifier that is identical to a target media identifier is found from a group of historical information identifiers, and then a corresponding review result is found, the review result is applied to the review process of the target media information. When the first media identifier is not found, the target media information is placed in a review pool, thereby avoiding the complex process of manually or machine reviewing each media information, and at the same time avoiding missed reviews, thereby improving the review efficiency of media information and reducing the probability of missed reviews.

[0110] As an optional solution, determining the first audit result and the second audit result respectively according to the set of historical information identifiers, the audit results corresponding to the set of historical information identifiers, and the target information identifier includes:

[0111] In a case where the audit types of the target media element and the media element associated with the first information identifier are different, the audit result corresponding to the first information identifier is determined as the audit result of the target media element.

[0112] Optionally, in this embodiment, the first type of media elements may include but are not limited to advertising slogans, videos, covers, etc., and the second type of media elements may include but are not limited to advertising slogans, videos, covers, etc. that are different from the first type.

[0113] Optionally, in this embodiment, when the target media element is a first-type media element, the media element associated with the first information identifier is a second-type media element, and the first type is different from the second type, the review result corresponding to the first information identifier is determined as the review result of the target media element, which may include but is not limited to, when it is obtained that the target media element is a first-type media element and the first information identifier corresponding to the target information identifier can be found in the historical review results, regardless of whether the media element corresponding to the first information identifier is the same as the first type, the review result corresponding to the first information identifier is determined as the review result of the target media element.

[0114] For example, taking the media resource as an advertisement, the above-mentioned media content is the advertising creativity, then the first group of media elements may include but not be limited to video, advertising words, and cover, the above-mentioned information identifier may include but not be limited to MD5 code, Advertisement 1 includes video 1, advertising words 1, and cover 1, Advertisement 2 includes video 2, advertising words 2, and cover 2, Advertisement 1 is an advertisement that has been reviewed by the target account, and Advertisement 2 is an advertisement uploaded by the target account for review. When the MD5 code of Cover 2 is the same as the MD5 code of Advertising Words 1, the review result of Advertising Words 1 is applied to Cover 2, and the review result of Cover 2 is directly determined without the need for subsequent review process.

[0115] Through the embodiments of the present application, when the audit type is different, for example, when only information identification for media content can be found, it can also be applied to the audit process for page information, further improving the audit efficiency of media information and reducing the probability of missed audits.

[0116] As an optional solution, reviewing each media element in the first group of media elements and each media element in the second group of media elements separately to determine a target review result of the media resource to be reviewed includes:

[0117] If the review results of each element in the first group of media elements and each element in the second group of media elements indicate that the review is passed, determining a first review result, wherein the first review result indicates that the to-be-published content is allowed to be published at the to-be-published location;

[0118] When the review result of any one of the first group of media elements and the second group of media elements indicates that the review has not been passed, a second review result is determined, wherein the second review result indicates that the to-be-published content is not allowed to be published at the to-be-published location.

[0119] Optionally, in this embodiment, the target media elements can be reviewed by machine review and / or manual review. Since the review standards involve a large number of scale-based penalties, such as exaggerated efficacy and low-perception videos, there is a fuzzy area in the penalty decision-making of human review and the threshold selection of machine review. After the media resources are split into media elements, manual review is conducted according to the media element type and the penalty result of each media element is given. Based on the penalty result of each media element, the machine review is targeted and modeled according to the media element content, media element review history, etc., which improves the accuracy of the model, facilitates the configuration of different machine review scales and policy thresholds, improves the quality of machine review, and reduces the machine review omission rate.

[0120] Optionally, in this embodiment, it may include but is not limited to determining that the media resource to be reviewed has passed the review as the above-mentioned first review result when the review results of each element in the first group of media elements and each element in the second group of media elements all indicate that the review has passed; and determining that the media resource to be reviewed has failed the review as the above-mentioned second review result when the review results of any element in the first group of media elements and the second group of media elements indicate that the review has not passed.

[0121] Through the embodiments of the present application, only when the review results of each element in the first group of media elements and each element in the second group of media elements indicate that the review has passed, the content to be published is allowed to be published in the to-be-published location, so as to improve the review quality and avoid the misreview of some media information, resulting in publication failure or other risks after the media information is published.

[0122] The following is a further explanation of this application with reference to specific examples:

[0123] With the development of commercial businesses and the launch of programmatic creative features, the volume of advertising creatives (corresponding to the aforementioned media content) undergoing review has increased exponentially, with human efficiency nearing saturation and a high rate of content reuse. Analysis shows that creatives are composed of three parts: the slogan, cover, and video (corresponding to the first set of media elements mentioned above), while the unit (corresponding to the aforementioned page information) consists of the landing page URL and additional information (corresponding to the second set of media elements mentioned above). Therefore, creatives or units can be broken down into the most detailed review units for review.

[0124] By adopting this application, the review results of videos, covers, and slogan elements can be applied to the same content creativity. It can also reduce the number of reviews, reduce labor costs, and thus improve the quality of reviews.

[0125] The steps in this embodiment include but are not limited to the following:

[0126] 1) Creative ideas are submitted for review in different versions:

[0127] The advertising content that is finally delivered is the advertiser's latest version of the creative and UNIT content. Even if the advertiser modifies the creative and UNIT multiple times from ad creation to ad review and triggers review, the advertising content that can finally be delivered is the advertiser's latest version of the creative and UNIT after approval.

[0128] Therefore, each time you submit your work for review, it will be accompanied by a version number, which will be used as a unique submission identifier through the creative ID / UNITD and version.

[0129] 2) Creative elements submitted for review:

[0130] Advertisements submitted for review on the DSP platform (Demand-Side Platform) are divided into two types: creative and unit. Creative consists of three parts: slogan, cover, and video, while unit consists of two parts: landing page URL and additional information. The review side breaks down the creative or unit into the most detailed review units for review, that is, the five elements of slogan, cover, video, landing page, and additional information are reviewed separately.

[0131] 3) Element aggregation principle:

[0132] According to the current situation, creatives are composed of videos, covers, and slogans (multiple slogans), and UNITs are composed of landing pages and additional information. An advertiser (corresponding to the aforementioned target account) will have multiple accounts, and these accounts will create multiple creatives with the same content. Since the MD5 of elements with the same content is the same, a HASH is generated by aggregating MD5 and the customer ID. This HASH is the unique identifier of an audit unit. If the same creative or UNIT is modified multiple times and triggers multiple versions to be submitted for review, during the period between the review and the sending of the review results, if the review is triggered, then for elements with the same content, if the element is still in the pending review pool, there is no need to insert it into the element review table, that is, into the pending review pool; otherwise, the element will be inserted into the element review table and enter the pending review pool, waiting for human or machine review.

[0133] Figure 4 is a schematic diagram showing another method for reviewing media resources according to an exemplary embodiment. Figure 4 As shown, including but not limited to the following steps:

[0134] S1, get the element (corresponding to the aforementioned media element);

[0135] S2, determining whether the media element is aggregated for the first time;

[0136] S3, if the result of S2 is yes, insert the element and the corresponding MD5 code into the element audit table (corresponding to the above historical audit result) successfully;

[0137] S4, if the result of S2 is no, determine whether the element is reviewed;

[0138] S5: If the result of S4 is yes, the element and the corresponding MD5 code are successfully inserted into the element audit table;

[0139] S6: If the result of S4 is negative, inserting the element and the corresponding MD5 code into the element audit table fails.

[0140] 4) Impact of dismantling elements on machine inspection:

[0141] Because the review criteria include numerous scale-based penalties, such as exaggerated efficacy and low-performing videos, there's ambiguity between human review decisions and the threshold selection for machine review. After breaking down the creative into its elements, human reviewers review them by element type and assign a penalty to each element. Based on these penalties, machine reviewers create targeted models based on element content and review history, improving their accuracy. Configuring different machine review scales and policy thresholds improves machine review quality and reduces missed rejections.

[0142] 5) Creative application of element results:

[0143] Once the creative's video, cover, and slogan elements have been reviewed, the creative is considered complete. Once the unit's landing page and additional information have been reviewed, the unit is considered complete. Once an element has been reviewed, the review results for that element will apply to all pending creatives or units using the same element.

[0144] Figure 5 is a schematic diagram showing another method for reviewing media resources according to an exemplary embodiment. Figure 5 As shown, it includes but is not limited to the following steps, where update represents the update operation of the database, set action = review status represents changing the review status of the element to pass / reject, and where hash = xxx and action = 0 represents the update operation for all elements with hash = xxx and action = pending review:

[0145] S1, enter the element review process;

[0146] S2, update element audit table set action = audit status where hash = xxx and action = 0;

[0147] S3, update element-creative relationship set action = review result, where hash = xxx and andaction = 0;

[0148] S4, determine whether all elements of the creative have been reviewed;

[0149] S5, if the result of S4 is negative, wait for the review results of the remaining elements;

[0150] S6, if the result of S4 is yes, determine whether all elements have passed the review;

[0151] S7, if the result of S6 is negative, reject the media resource review request;

[0152] S8. If the result of S6 is yes, the media resource review request is approved.

[0153] Through this embodiment, the creativity or UNIT is split into video, cover, slogan, landing page, and additional information, thereby improving the review quality. Reviewers only need to focus on the compliance of the content itself, aggregate the elements through MD5 and account ID, and aggregate all the same elements to be reviewed into an audit unit, which greatly reduces the number of reviews, reduces labor costs, and improves the review timeliness.
