Fig. 1 is a schematic flow chart of a policy recommendation method based on user offloading according to an embodiment of the present invention.

S10, constructing an experiment domain, wherein the experiment domain comprises experiment layers and strategies, configuring domain IDs (Identity codes) for the experiment domains, configuring layer IDs for each experiment layer, and configuring strategy IDs for each strategy.

In this embodiment, an experimental domain may be constructed for each task field, or an experimental domain may be constructed for each product, such as: an experimental domain may be constructed for the information recommendation task, or an experimental domain may be constructed for a product a, which is not limited in the present invention.

Therefore, when the task field or the execution environment and the like change, the subsequent strategy recommendation or strategy verification can be continuously executed only by updating the domain ID of the experimental domain, and the execution efficiency is improved.

In at least one embodiment of the present invention, the constructing the experimental domain comprises:

creating at least one of the experimental layers for the experimental domain;

For example: the experimental domain may include a recall layer, a rough layer and a fine layer, wherein the recall layer includes a recall policy a and a recall policy B, a bucket range of the recall policy a may be configured as [0,35 ], a bucket range of the recall policy B may be configured as [35,100 ], the rough layer includes a rough policy a and a rough policy B, the bucket range of the rough policy a may be configured as [0,40 ], a bucket range of the recall policy B may be configured as [40,100 ], the fine layer includes a fine policy a and a fine policy B, the bucket range of the fine policy a may be configured as [0,60 ], and the bucket range of the recall policy B may be configured as [60,100 ].

Of course, in other embodiments, a traffic support layer may also be configured in the experimental domain, where the traffic support layer refers to a policy for relevant staff to recommend specified content according to hotspots and the like in specified time.

All the experimental layers have 100% of flow, and the strategy for creating different flow can be created only by adding all the flow in the corresponding experimental layer to no more than 100%, for example: 3 30% recall strategies, such as recall strategy a, recall strategy b and recall strategy c, can be created at the recall layer, which is 90% of the true flow and 10% of the empty flow. It is also possible to create 50% recall policy a, 30% recall policy b, 20% recall policy c, for a total of 100% traffic.

Through the implementation mode, a unified experimental domain is created for recommending the auxiliary strategy, and updating and management are facilitated.

S11, obtaining a user set constructed in advance, and obtaining the user ID of each user in the user set and the user number of the users in the user set.

In at least one embodiment of the invention, before obtaining the pre-constructed set of users, the method further comprises:

connecting to a designated platform at preset time intervals;

acquiring log data from the specified platform;

extracting user data in the log data;

and constructing the user set according to the user data.

The preset time interval may be configured by a user, for example, every 10 days, so as to implement periodic update of the user set.

It can be understood that many policy recommendation algorithms have strong correlation with the interests and behaviors of users, and the distribution of the interests and behaviors of real users cannot be simulated really by using virtual users, so that the logic of the related policy recommendation algorithms cannot be verified effectively.

In the embodiment, the problem that the recommended strategy is not matched with the user is effectively solved by acquiring the real user data as the data basis for the follow-up strategy recommendation.

S12, creating a thread pool, and acquiring threads from the thread pool as shunting threads, wherein the number of the shunting threads is the same as the number of the users.

In at least one embodiment of the present invention, the obtaining a thread from the thread pool as a split thread includes:

acquiring an idle thread in the thread pool;

acquiring the resource occupancy rate of each idle thread;

sequencing the idle threads according to the sequence of the resource occupancy rates from low to high to obtain a thread sequence;

and acquiring threads from the thread sequence as the shunting threads according to the sequence from front to back.

Through the implementation mode, the thread with the best performance can be selected from the created thread pool to execute the subsequent shunting task, and the execution effect of the task is further ensured.

S13, the shunting thread is started in parallel, and the user ID, the domain ID and the layer ID of each user are processed by the shunting thread to obtain at least one target value.

In the above embodiment, by starting the split threads in parallel, a task can be executed simultaneously by using multiple threads, and the execution efficiency of the task is improved.

In at least one embodiment of the present invention, the processing, by using the forking thread, the user ID, the domain ID, and the layer ID of each user to obtain at least one target value includes:

randomly distributing the shunting thread to each user to obtain the thread of each user;

performing hash operation on the user ID, the domain ID and each layer ID of each user through the thread of each user to obtain a hash value of each user;

and calculating the quotient of the hash value of each user and a preset threshold value to obtain the at least one target value.

The preset threshold may be configured by a user, such as 100.

In the above embodiment, the characteristics of the hash algorithm, i.e., infinite input and finite output, are used to make the target value calculated based on the user ID of each user unique.

And S14, performing matching calculation in the experimental domain by using the at least one target value, and determining the matched strategy as at least one target strategy.

Specifically, the performing matching calculation in the experimental domain by using the at least one target value, and determining the matched strategy as the at least one target strategy includes:

acquiring a barrel position range of each experimental layer in the experimental domain;

detecting a corresponding strategy of each target bucket position range in each experimental layer;

and combining the detected strategies to obtain the at least one target strategy.

For example: taking the above example in mind, for the target value 38, matching with the bucket level range of each experimental layer, and determining that the bucket level range on the recall layer is [35,100 ], the method corresponds to the recall policy B; the bucket position range on the coarse exhaust layer is [0,40 ], and the bucket position range corresponds to the coarse exhaust strategy A; and if the bucket position range on the fine-ranking layer is [0,60 ], the fine-ranking strategy A is corresponding to. Further, the target policy corresponding to the target value 38 may be determined as follows: the recall strategy B, the rough ranking strategy A and the fine ranking strategy A.

Through the implementation mode, the corresponding strategy can be automatically matched by combining a hash algorithm.

S15, obtaining the strategy ID of the at least one target strategy, and generating at least one path according to the strategy ID of the at least one target strategy.

Specifically, the generating at least one path according to the policy ID of the at least one target policy includes:

determining the strategy ID belonging to the same user in the strategy ID of the at least one target strategy as a strategy group;

calling a sort function to sort the strategy IDs in each strategy group to obtain a sorting result corresponding to each user;

splicing the strategy IDs in the corresponding strategy groups according to the sequencing result corresponding to each user to obtain a path corresponding to each user;

and integrating the path corresponding to each user to obtain the at least one path.

For example: when a character string X is generated by concatenation, the character string X may be determined as a path and recorded as path _ key.

And S16, analyzing the at least one path to obtain a strategy recommendation result.

In at least one embodiment of the present invention, the analyzing the at least one path to obtain the policy recommendation result includes:

acquiring a user ID corresponding to each path;

determining a user corresponding to each path according to the user ID of each path;

calculating the number of users corresponding to each path;

acquiring a strategy ID on each path;

identifying a strategy corresponding to each path according to the strategy ID on each path;

and converting the strategy recommendation file corresponding to each path into a specified format to obtain the strategy recommendation result.

In this embodiment, the specified format may be a txt format.

Of course, in other embodiments, the policy recommendation result may further include a traffic ratio.

For example: for the path '1372482059966201856,1372485205305307136,1372487988066627584', it is determined by analysis that the number of corresponding users is 'count': 4, the user IDs are 'IDs': 1041142818','1046816297','1041239090','1050175706', the policies corresponding to the policy IDs are' name ': all _ a', 'rank _ a', 'rerank _ b', and the traffic ratio is 'rate': 0.04.

Through the implementation mode, the strategy recommendation can be automatically executed through a series of data processing, and the strategy corresponding to each user can be quickly identified.

In at least one embodiment of the present invention, after obtaining the policy recommendation result, the method further includes:

when a policy to be verified is obtained, determining a path corresponding to the policy to be verified as a target path;

acquiring a target user corresponding to the target path;

detecting buried point data corresponding to the target user;

when the buried point data corresponding to the target user are matched with the target path, determining that the strategy to be verified passes verification; or

And when data in the buried point data corresponding to the target user is not matched with the target path, determining that the strategy to be verified is not verified.

The policy to be verified may include a new policy or a common policy.

It can be understood that when testing various types of recommendation strategies, especially for large traffic scenarios (e.g. with more than ten recommendation strategies), in order to verify a strategy, it is often necessary to try dozens of users to hit the strategy to be verified, and even sometimes more users are tried to miss the strategy to be verified. In addition, for newly added strategies, the amount may be only 1% or 5%, in which case it is more difficult to hit the relevant strategy.

In this embodiment, because the user set is continuously updated, when there is a newly added policy, the policy recommendation result is also updated synchronously, so that when there is a policy that needs to be verified, a user corresponding to the policy to be verified can be found by performing reverse-pushing on the policy recommendation result, and then whether data of the corresponding user completely satisfies the policy to be verified is detected in a targeted manner, so that accurate verification of the policy to be verified can be achieved, the verification efficiency is improved, and the problem of resource and time consumption caused by repeated experiments is avoided.

After verification, the strategy is verified in the original mode, and due to the fact that the problem that a user is randomly searched and the specified strategy is difficult to hit exists, verification time is usually 30 minutes, the time consumption can be reduced to 2 seconds by adopting the method for verifying the strategy, namely the user is locked within 2 seconds, whether the user meets the specified strategy is detected, and the verification efficiency of online production is effectively improved.

Therefore, the embodiment can be used for testing or development to assist relevant workers in quickly verifying a specific recommendation strategy.

It should be noted that, in order to further improve the security of the data and avoid malicious tampering of the data, the policy recommendation result may be stored in the blockchain node.

It can be seen from the above technical solutions that, in the present invention, an experimental domain is constructed, where the experimental domain includes experimental layers and policies, a domain ID is configured for the experimental domain, a layer ID is configured for each experimental layer, a policy ID is configured for each policy, a pre-constructed user set is obtained, a user ID of each user in the user set and the number of users in the user set are obtained, a thread pool is created, and a thread is obtained from the thread pool as a shunting thread, where the number of the shunting threads is the same as the number of users, the shunting thread is started in parallel, the user ID of each user, the domain ID, and each layer ID are processed by the shunting thread to obtain at least one target value, and by starting the shunting thread in parallel, a task can be executed simultaneously by using multiple threads, the execution efficiency of the task is improved, and the at least one target value is used for performing matching calculation in the experimental domain, and determining the matched strategy as at least one target strategy, acquiring a strategy ID of the at least one target strategy, generating at least one path according to the strategy ID of the at least one target strategy, analyzing the at least one path to obtain a strategy recommendation result, and then automatically executing strategy recommendation through a series of data processing to quickly identify the strategy corresponding to each user.

calling a sort function to sort the strategy IDs in each strategy group to obtain a sorting result corresponding to each user;

splicing the strategy IDs in the corresponding strategy groups according to the sequencing result corresponding to each user to obtain a path corresponding to each user;

and integrating the path corresponding to each user to obtain the at least one path.

For example: when a character string X is generated by concatenation, the character string X may be determined as a path and recorded as path _ key.

The analyzing unit 107 analyzes the at least one path to obtain a policy recommendation result.

In at least one embodiment of the present invention, the analyzing unit 107 analyzes the at least one path, and obtaining the policy recommendation result includes:

acquiring a user ID corresponding to each path;

determining a user corresponding to each path according to the user ID of each path;

calculating the number of users corresponding to each path;

acquiring a strategy ID on each path;

identifying a strategy corresponding to each path according to the strategy ID on each path;

and converting the strategy recommendation file corresponding to each path into a specified format to obtain the strategy recommendation result.

In this embodiment, the specified format may be a txt format.

Of course, in other embodiments, the policy recommendation result may further include a traffic ratio.

Through the implementation mode, the strategy recommendation can be automatically executed through a series of data processing, and the strategy corresponding to each user can be quickly identified.

In at least one embodiment of the invention, after a policy recommendation result is obtained, when a policy to be verified is obtained, a path corresponding to the policy to be verified is determined as a target path;

acquiring a target user corresponding to the target path;

detecting buried point data corresponding to the target user;

when the buried point data corresponding to the target user are matched with the target path, determining that the strategy to be verified passes verification; or

And when data in the buried point data corresponding to the target user is not matched with the target path, determining that the strategy to be verified is not verified.

The policy to be verified may include a new policy or a common policy.

Therefore, the embodiment can be used for testing or development to assist relevant workers in quickly verifying a specific recommendation strategy.

It should be noted that, in order to further improve the security of the data and avoid malicious tampering of the data, the policy recommendation result may be stored in the blockchain node.
