It should also be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for presentation, analyzed data, etc.) referred to in the present disclosure are both information and data that are authorized by the user or sufficiently authorized by various parties.

Referring to fig. 1, a schematic diagram of an application environment of a content recommendation method according to an exemplary embodiment is shown, where the application environment may include a terminal 110 and a server 120, and the terminal 110 and the server 120 may be connected through a wired network or a wireless network.

The terminal 110 may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, and the like. The terminal 110 may have client software, such as an Application (App for short), installed therein, where the client software provides a service content display function, and the Application may be a stand-alone Application or a sub-program in the Application. Illustratively, the application may include a short video application, a live application, a shopping application, and the like. The user of the terminal 110 may log into the application through pre-registered user information, which may include an account number and a password.

The server 120 may be a server providing a background service for an application in the terminal 110, where a content recommendation system is deployed on the server, the server 120 obtains a content recommendation request of a target object through the content recommendation system, performs mixed arrangement processing on a service content sequence generated by each service in response to the content recommendation request to obtain a mixed arrangement content sequence recommended to the target object, and sends the recommended mixed arrangement content sequence to the terminal 110 of the target object, where each service is a service with a different service type, such as a native service (live broadcast, short video, cold start, and the like), a promotion service (an information flow service, a paid promotion service, and the like), and the mixed arrangement content sequence recommended to the target object may include service contents with different service types.

The server 120 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a CDN, a big data and artificial intelligence platform, and the like.

Fig. 2 is a flowchart illustrating a content recommendation method according to an exemplary embodiment, and as shown in fig. 2, the content recommendation method is applied to the server in fig. 1, and includes the following steps.

In step S201, a plurality of service content sequences are obtained, each of the service content sequences corresponds to a different service type, and each of the service content sequences includes a plurality of service contents ordered based on a degree of correlation with a target object.

The service content sequence of each service type can be obtained by content recall, fine-ranking, coarse-ranking and rearrangement screening in sequence, generally, the service contents in each service content sequence are ranked from high to low according to the degree of correlation with the target object, and the higher the degree of correlation is, the more interested the target object is in the corresponding service contents, the more likely the target object is to browse the service contents. The business content may include short videos, live broadcasts, news, merchandise, and so on.

In a specific implementation, when a content recommendation request is initiated by a target object, service services call back service content from respective service content sets in response to the content recommendation request, and perform fine-arranging, coarse-arranging and rearrangement processing on the called-back service content in sequence to form a service content sequence of each service, and each service sends the respective service content sequence to a mixed arrangement service, so that the mixed arrangement service obtains the service content sequence of each service type.

In step S203, the service content sequences are recalled sequentially based on preset sequence constraint information, so as to obtain a plurality of mixed content sequences.

Wherein each of the shuffled content sequences includes service content of at least one service type.

The preset sequence constraint information is used for constraining the service contents of some service types in the mixed content sequence so as to ensure that the mixed content sequence recalled by the sequence meets some basic service requirements.

In practical application, the preset sequence constraint information may consider introducing control on exposure positions and exposure intervals of service contents of certain service types, for example, the preset sequence constraint information may be constraints on exposure positions and exposure intervals of promotion contents (such as advertisements) in each mixed content sequence, such as "there need to be 4 platform native contents at least between two promotion contents", "the first 3 exposure contents after a user enters a platform cannot be promotion contents", and the like, where the platform native contents may be contents uploaded to the platform by the user, and for example, the native contents in a short video platform may be recorded videos uploaded by the user, shot pictures, and the like.

In a specific implementation, the sequence recall may use an enumeration method to enumerate all mixed content sequences that satisfy the preset sequence constraint information.

In practical application, the ordering of each service content in the service content sequence entering the shuffling stage is an optimal decision optimized by the rearranging stage, and if the ordering sequence of each service content in the corresponding service content sequence is damaged in the shuffling stage, the final recommendation effect is adversely affected. Based on this, in an exemplary embodiment, in a plurality of mixed content sequences obtained based on the above-mentioned sequence recall, the service content of each service type in each mixed content sequence is arranged in the same order in the mixed content sequence as the service content sequence corresponding to the service type.

For example, a certain shuffled content sequence is { a1, B1, a2, a3, B2}, where the service contents a1, a2, a3 are from the service content sequence of service type a, and the service contents B1, B2 are from the service content sequence of service type B, then the order of the service contents a1, a2, a3 in the shuffled content sequence is the same as the order of the service contents in service type a, and the order of the service contents B1, B2 in the shuffled content sequence is the same as the order of the service contents in service type B.

In the embodiment, the sequence recall is performed on the premise of keeping the arrangement sequence of the service contents of each service type in the corresponding service content sequence, so that the optimal exposure sequence decided by each service in the rearrangement stage is prevented from being covered and damaged in the mixed arrangement stage, and the maximum utilization of the display position resource can be realized by the subsequently screened mixed arrangement content sequence.

In step S205, a target resource utilization degree corresponding to each of the mixed content sequences is determined.

The target resource utilization degree represents the utilization degree of the corresponding mixed content sequence on the display position resource, and is a value consideration of the whole sequence, and generally, the higher the utilization degree of the sequence on the display position resource is, the higher the sequence value of the corresponding mixed content sequence is.

In step S207, a target mixed content sequence is selected from the plurality of mixed content sequences based on a target resource utilization degree corresponding to each mixed content sequence.

Wherein the target shuffled content sequence is for recommendation to the target object. Generally, the utilization degree of the target resource corresponding to the target mixed content sequence is characterized by the maximum utilization degree of the display position resource. For example, when the target resource utilization degree is expressed in the form of a numerical value, the shuffled content sequence whose numerical value is the largest may be selected as the target shuffled content sequence.

In the embodiment, the utilization program of the whole sequence to the display position resource is considered from the perspective of the sequence, and the utilization degree of the whole sequence to the display position resource is actually integrated with the influence of the exposure position, so that the method is more suitable for the actual exposure scene, the maximum utilization of the display position resource can be realized, and the resource utilization rate is improved.

In an exemplary embodiment, the service content in the mixed content sequence includes a target service content and a non-target service content, where the target service content is a service content corresponding to a service type constrained by the preset sequence constraint information, and the non-target service content is a service content corresponding to a service type not constrained by the preset sequence constraint information, that is, the non-target service content is a service content in the mixed content sequence except the target service content. For example, if the preset sequence constraint information is that "there are at least 4 platform native contents needed between two promotion contents", the service type that the promotion contents are constrained may also be referred to as a target service type, and the service type that the platform native contents are unconstrained may also be referred to as a non-target service type. Therefore, the recalled mixed-ranking content sequence is constrained by the preset sequence constraint information in the sequence recall process, because the exposure of the constrained service type corresponding to the service content brings a certain loss of resource utilization of the display position.

In order to measure the utilization degree of target resources corresponding to the mixed content sequence, firstly, the resource utilization degree of the business content needs to be measured, the resource utilization degree of the business content represents the utilization degree of the business content on the display position resource, generally, the utilization degree of the business content on the display position resource can reflect the self value of the business content, the higher the utilization degree of the business content on the display position resource is, the higher the self value of the business content is, and conversely, the lower the utilization degree of the business content on the display position resource is, the lower the self value of the business content is.

For example, the value of the business content itself can be measured from both the user dimension and the platform dimension, that is, the resource utilization of the business content can be measured from the user dimension and the platform dimension. Based on this, in step S201, after acquiring a plurality of service content sequences, the method further includes:

determining the resource utilization degree of each target business content according to the unit virtual resource consumption and the object correlation degree corresponding to each target business content in the target business content sequence; the object relevance degree characterizes the relevance degree of a corresponding target business object and the target object;

The target service content sequence is a service content sequence corresponding to a service type (namely, a target service type) constrained by preset sequence constraint information, and the non-target service content sequence is a service content sequence corresponding to a service type (namely, a non-target service type) which is not constrained.

Specifically, the historical operation behavior information corresponding to the non-target service content may include browsing duration, interaction rate, and the like, and generally, the longer the browsing duration is, the higher the interaction rate is, the greater the utilization of the non-target service content on the display position resource can be achieved, that is, the higher the resource utilization of the non-target service content is. In order to improve the content recommendation efficiency, for example, the click-through rate pltr estimated by the non-target service content in the fine ranking stage may be obtained, and the resource utilization rate of the non-target service content may be determined based on the click-through rate pltr, so as to obtain the non-target service content in the non-target service content sequenceiFor example, the non-target service contentiThe resource utilization degree of (c) can be calculated by the following formula (1):

wherein the content of the first and second substances,

representing non-targeted business contentiThe resource utilization of (2);

the weight corresponding to the non-target service type is represented and can be set according to actual needs;

representing non-targeted business contentiCorresponding click-through rate.

For the target service content sequence, the target service content in the target service content sequence is usedjFor example, the target service contentjThe resource utilization degree of (c) can be calculated by the following formula (2):

wherein

Representing targeted business contentjResource utilization of (a);

and

the weight corresponding to the target service type is expressed and can be set according to actual needs;

representing object relevance;

represents a unit of virtual resource consumption, such as the cost of consumption for an advertisement per thousand people presented. It should be noted that both the object correlation and the unit virtual resource consumption may be estimated based on the preamble link of the service corresponding to the target service content sequence.

According to the embodiment, the self values of the service contents of different service types are quantized from the two angles of the user dimension and the platform dimension respectively, so that the utilization degree of the display position resources of each service content can be accurately measured.

Based on this, in an exemplary embodiment, as shown in fig. 3, the step S205 may be implemented by:

in step S301, an original resource utilization degree of the mixed content sequence is determined based on the resource utilization degree of each service content in the mixed content sequence.

The original resource utilization degree of the mixed content sequence refers to the utilization degree of the mixed content sequence to the display position resource without considering the resource utilization loss corresponding to the sequence. The resource utilization loss represents the negative influence on the resource utilization of the display position, the larger the resource utilization loss is, the larger the negative influence on the resource utilization of the display position is, and otherwise, the smaller the resource utilization loss is, the smaller the negative influence on the resource utilization of the display position is.

In the information flow scene, the utilization of the service content to the display position resource is embodied by exposure, and usually the user browses the content sequence from front to back, which results in that the probability of obtaining exposure for the content at the front of the sequence position is higher than that for the content at the back of the sequence position, that is, the exposure position will affect the self value of the service content in the mixed content sequence. In order to improve the accuracy of determining the target resource utilization rate corresponding to the mixed content sequence, the resource utilization rate of the service content needs to be corrected according to the sequence position of the service content in the mixed content sequence. In an exemplary embodiment, step S301, when implemented, may include:

The positive correlation relationship between the position weight and the sequence position of the corresponding service content in the mixed content sequence means that the position weight corresponding to the sequence position before is larger, and the position weight corresponding to the sequence position after is smaller.

In the above embodiment, the resource utilization of the service content is corrected by the sequence position of the service content in the mixed content sequence, which is beneficial to improving the accuracy of the subsequent determination of the original resource utilization of the mixed content sequence.

In an exemplary embodiment, obtaining the resource utilization degree of each service content in the mixed content sequence may include: and acquiring the resource utilization degree of each target service content in the mixed content sequence and the resource utilization degree of each non-target service content in the mixed content sequence. By respectively obtaining the resource utilization degree of the target service content and the non-target service content in the mixed content sequence, the original resource utilization degree of the mixed content sequence can be accurately obtained.

Accordingly, in an exemplary embodiment, determining the location rights of each business content in the shuffled content sequence may include:

Specifically, when determining the position weight of each service content in the mixed content sequence, the target service content and the non-target service content in the mixed content sequence are considered respectively, so that the influence of the exposure position on the self value of the service contents of different service types can be measured more accurately, and the resource utilization rate of each service content in the mixed content sequence can be corrected more accurately.

In particular embodiments, the location weight of the non-targeted business content

And location weighting of target business content

Can be calculated by the following equations (3) and (4):

wherein the content of the first and second substances,

；

and

are all taken as values of [0, 1%]Parameter values in between, for example both may take 0.9;

and

the position numbers in the shuffled content sequence are usually consecutive arabic numerals starting from 0, that is, the position number of the first sequence is 0, and then sequentially increases toward the position number of the last sequence. The position weight can show a change trend from big to small from the first position of the sequence to the end of the sequence through the calculation formula.

Taking non-target service content as native content (such as short video uploaded by a user, live broadcast, etc.) and target service content as promotion content (such as advertisement), the calculation of the position weight corresponding to the target service content will be exemplarily described below with reference to fig. 4. As shown in FIG. 4, the promotion content ad1 in the mixed content sequence 1 is located at the first position of the sequence and the position serial numberposIf the position weight is 0, the position weight corresponding to the promotion information ad1 in the mixed content sequence 1 is

(ii) a The promotion information ad1 in the mixed content sequence 2 is positioned at the 2 nd position of the sequence and has the position serial numberposIf the position weight is 1, the position weight corresponding to the promotion information ad1 in the mixed content sequence 2 is

。

It will be appreciated that the original resource utilization of the shuffled content sequence can be obtained by weighting and summing the location weights of the non-targeted traffic content in the shuffled content sequence and the resource utilization of the corresponding non-targeted traffic content

And carrying out weighted summation based on the position weight of each target service content in the mixed content sequence and the resource utilization degree of the corresponding target service content to obtain

Then, the original resource utilization of the mixed content sequence is obtained by combining the two weighted sums, that is, the original resource utilization of the mixed content sequence can be expressed as the following formula (5):

in particular, the method comprises the following steps of,

wherein the content of the first and second substances,

representing non-targeted traffic content in a shuffled content sequenceiPosition weight of [ 1, 0 ], which is a value of]To (c) to (d);

representing non-targeted business contentiResource utilization of.

In particular, the method comprises the following steps of,

wherein the content of the first and second substances,

In step S303, a target resource utilization loss of the shuffled content sequence is determined based on the resource utilization loss of the target service content in the shuffled content sequence.

Because the utilization of the display position resource of the sequence by the target service content has a certain adverse effect, especially when the target service content in the mixed content sequence is dense, the adverse effect is larger, and on the premise of meeting the preset sequence constraint information, the mixed content sequence with larger target service content interval can better utilize the display position resource compared with the mixed content sequence with small target service content interval. Therefore, when measuring the target resource utilization of the mixed content sequence, the adverse effect of the exposure density of the target service content in the mixed content sequence on the display position resource utilization needs to be considered, so as to improve the accuracy of the target resource utilization corresponding to the mixed content sequence.

Based on this, in order to improve the accuracy of recommendation based on the target resource utilization of the shuffled content sequence, in an exemplary embodiment, the step S303 may include:

determining a content interval corresponding to each target service content in the mixed content sequence;

determining resource utilization loss corresponding to each target service content based on the comparison condition of the content interval corresponding to each target service content in the mixed content sequence and a content interval threshold;

Wherein, the content interval refers to the number of the service contents spaced between the corresponding target service contents and the target service contents ordered at the previous position. It should be noted that, the target service content ordered at the previous position may be the target service content ordered at the previous position in the mixed content sequence where the target service content is located; if the target service content is the first target service content to be exposed in the mixed content sequence, the target service content ordered at the previous position is the last exposed historical target service content in the last exposed historical mixed content sequence.

As shown in fig. 5, in the current mixed content sequence (which is any one of the mixed content sequences), the target traffic content ordered immediately before the target traffic content ad1 is the historical target traffic content ad in the history mixed content sequence exposed most recently, the target traffic content ordered immediately before the target traffic content ad2 is ad1, the content interval corresponding to ad1 is 4, and the content interval corresponding to ad2 is 5.

In the embodiment of the present disclosure, when the content interval corresponding to the target service content is smaller than the content interval threshold, it is considered that the content interval corresponding to the target service content does not adversely affect the utilization of the display location resource.

In a specific implementation, the resource utilization loss corresponding to each target service content in the mixed content sequence may be calculated by the following formula (8):

wherein, the first and the second end of the pipe are connected with each other,

representing targeted business content in a shuffled content sequencejResource utilization loss of (2);

representing targeted business content in a shuffled content sequencejThe content interval of (a);

in the representationA capacitive spacing threshold;

is a preset parameter value with the value of [0, 1%]For example, 0.5 may be used.

For example, the sum of the resource utilization losses corresponding to the target service contents in the shuffled content sequence may be used as the target resource utilization loss of the shuffled content sequence.

In the above embodiment, the adverse effect of the exposure density of the target service content in the mixed content sequence on the resource utilization of the display position is measured, which is beneficial to improving the accuracy of the utilization rate of the target resource corresponding to the mixed content sequence, and further improving the accuracy of content recommendation.

In step S305, a target resource utilization degree of the mixed content sequence is obtained based on the original resource utilization degree and the target resource utilization loss of the mixed content sequence.

Specifically, the target resource utilization of the shuffled content sequence may be determined from a difference between an original resource utilization of the shuffled content sequence and a target resource utilization loss of the shuffled content sequence.

In the above embodiment, the utilization condition of each mixed content sequence on the display position resource is evaluated from the sequence dimension in combination with the resource utilization degree and the resource utilization loss of the sequence, and the largest target mixed content sequence is selected as the target mixed content sequence to be recommended to the user based on the target resource utilization degree obtained by the evaluation, so that the maximum utilization of the display position resource can be realized.

In consideration of the fact that in practical application, a user can continuously request a next mixed content sequence in the process of browsing information, and as a part of context, a historical exposure sequence can influence the decision of a subsequent sequence. Therefore, in the decision process of the shuffling stage, the value maximization of the shuffling sequence in a single request cannot be considered, and the influence of the current sequence on the value of the subsequent sequence should be considered, so as to obtain the shuffling scheme for globally showing the position resource utilization maximization in a use time period. The following describes the influence of the current sequence on the subsequent sequence in a specific application scenario.

Assume that a minimum of 4 pieces of native content (e.g., short video recorded by a user, live broadcast, etc.) are defined between two promotional content (e.g., advertisements) during a sequence recall. For the current request, two pieces of promotion content are to be released, and 1 piece of promotion content, 2 pieces of promotion content or no promotion content can be selectively released, wherein the content resource utilization information corresponding to the promotion content ad2

Is a very small positive number, i.e., the promotional content has a low utilization of the exhibition location resource. However, if only the sequence value maximization in the current request is considered, as shown in fig. 6, the mixed content sequence 1 and the mixed content sequence 2 corresponding to the recall of the current request sequence are shown, since one more promotion content is released in the mixed content sequence 1, the sequence resource utilization information of the mixed content sequence 1 is higher than that of the sequence resource utilization information of the sequence 2. And if the influence of the current sequence on the subsequent sequence is taken into consideration, the promotion content ad is arranged in the next exposure sequence corresponding to the mixed content sequence 2 under the limit that the promotion content interval is not less than 4_nextThe highest energy is arranged at the first of the sequence, and the promotion content ad is arranged in the next exposure sequence corresponding to the mixed content sequence 1_nextThe highest content can only be arranged at the 5 th position of the sequence, and the popularization content ad can be known by combining the formulas (4) and (7)_nextCan be affected by a significant positional compromise. Therefore, after considering the influence of the current sequence on the subsequent sequence, the shuffled content sequence 1 is not necessarily better than the shuffled content sequence 2 from the viewpoint of the maximum utilization of the global presentation position resource.

Based on this, in an exemplary embodiment, the obtaining the target resource utilization loss of the mixed content sequence based on the resource utilization loss corresponding to each target service content in the mixed content sequence may include:

Specifically, the first resource utilization loss for the shuffled content sequence may be calculated based on the following equation (9):

wherein the content of the first and second substances,

a first resource utilization penalty representing a shuffled content sequence;

represents the loss weight of the first sequence and takes the value of [0, 1%]Specific numerical values can be set according to actual experience;

representing targeted business content in a shuffled content sequencejThe content resource utilization loss.

Taking the current shuffle content sequence shown in FIG. 5 as an example, the settings are set

Then the first resource utilization penalty of the current shuffled content sequence shown in fig. 5 is

。

In the above embodiment, from the angle of the influence of the current mixed content sequence on resource utilization of the subsequent sequence display position, the highest sequence position of the service content of the target service type in the next recommendation is determined based on the sequence position of the target service content in the mixed content sequence and the preset sequence constraint information, and the second resource utilization loss of the mixed content sequence is determined based on the highest sequence position, so that the target resource utilization loss of the mixed content sequence is determined by combining the first resource utilization loss and the second resource utilization loss, that is, the target resource utilization loss of the mixed content sequence is formed by the first resource utilization loss and the second resource utilization loss of the mixed content sequence, which is favorable for realizing maximization of resource utilization of the global display position within a period of time. It should be noted that, in the embodiments of the present disclosure, the sequence position is higher before the sequence position is closer, that is, the first sequence is the highest sequence position, the last sequence is the lowest sequence position, and the sequence positions between the first sequence and the last sequence are sequentially lower.

Specifically, the sequence position of the last exposed target service content in the mixed content sequence may be determined, then the number of the minimum service contents requiring the interval between adjacent target service contents is determined based on the preset sequence constraint information, and the highest sequence position of the service content of the target service type in the next recommendation may be determined based on the number of the minimum service contents at the interval and the sequence position. Taking the mixed content sequence 1 in fig. 6 as an example, the target service content exposed last is located at the end of the sequence, and assuming that the preset sequence constraint information is that at least 4 pieces of non-target service content are spaced between two target service contents, it may be determined that the highest sequence position of the service content of the target service type in the next recommendation is 5.

In an exemplary embodiment, when determining the second resource utilization loss of the shuffled content sequence based on the above-mentioned highest sequence position, the method may include:

and determining the second resource utilization loss of the mixed content sequence according to the target position weight.

In a specific implementation, the target location weight may be calculated based on the foregoing formula (4), that is, the target location weight may be expressed as

Wherein, in the step (A),

and the position serial number of the highest sequence position corresponding to the service content of the target service type in the next recommendation. Then the second resource utilization penalty for the shuffled content sequence can be calculated by equation (10) below:

wherein the content of the first and second substances,

a second resource utilization penalty representing a shuffled content sequence;

the weight indicating the second sequence loss may be set according to practical experience, or may be set based on the contribution value of the target object to the platform in practical application, for example, the higher the contribution value is, the higher the corresponding contribution value is

The larger may be.

The second resource utilization loss of the mixed content sequence can be obtained more accurately by combining the target position weight of the highest sequence position in the above embodiment.

Illustratively, the target resource utilization of the shuffled content sequence may be calculated based on the following equation (11):

wherein the content of the first and second substances,

indicating a target resource utilization of the shuffled content sequence.

In the above embodiment, when determining the target resource utilization degree corresponding to the mixed content sequence, the influence of the exposure position on the resource utilization degree of the business content, the influence of the exposure density of the target business content on the resource utilization degree of the display position, and the influence of the current mixed content sequence on the resource utilization degree of the display position of the subsequent sequence are comprehensively considered, so that the utilization condition of each mixed content sequence on the display position resource within a period of time is more comprehensively evaluated from the sequence dimension, the maximum mixed content sequence is selected as the target mixed content sequence to be recommended to the user based on the target resource utilization degree obtained by the evaluation, and the maximum utilization of the display position resource within a period of time is realized.

In order to better understand the technical solution of the embodiment of the present disclosure, the following description is given with reference to the mixed-arranging technical architecture diagram of fig. 7, taking non-target service content as native content and target service type as popularization content as an example.

As shown in fig. 7, the native content may include short videos recorded by the user, live and cold start service content, and the like, and the promotion content may include information stream advertisements, paid promotion content, and the like. In the mixed ranking stage, a native content sequence { pid1, pid2, pid3, pid4, pid5 and pid6} and a promotion content sequence { ad1, ad2}, { fans1 and fans2} are obtained; then, the first calculating module calculates, for each sequence, the resource utilization of each content in the sequence, which is presented in a form of a value in fig. 7, and the specific calculating manner may refer to the foregoing related description about the resource utilization of the service content in the embodiment of the present disclosure, and is not described herein again; then, the sequence recall module recalls the native content sequence and the popularization content sequence in sequence based on preset sequence constraint information to obtain a recall sequence set comprising a plurality of mixed content sequences; and then entering a sequence evaluation module, evaluating each mixed content sequence by the sequence evaluation module from three angles of influence of the exposure position on resource utilization of each content, influence of popularization content density on resource utilization of the display position and influence of the current sequence on resource utilization of the display position of a subsequent sequence to obtain target resource utilization of each mixed content sequence, presenting the target resource utilization in a sequence value form, and issuing the mixed content sequence with the maximum sequence value as an optimal mixed content sequence.
