The electronic device for model training may be the same as or different from the electronic device for determining product information. If the electronic equipment for model training is different from the electronic equipment for determining the product information, the electronic equipment for model training trains the original prediction model in advance according to the second service experience information and the corresponding label thereof, after acquiring the trained prediction model, the trained prediction model is stored in the electronic equipment for determining the product information, and the electronic equipment for subsequently determining the product information can determine a first target product recommended to a target account through the trained prediction model, so that the product information of the first target product is recommended to the target account.
In the embodiment of the invention, the second service experience information of any sample account is input into the original prediction model, a second target product corresponding to the input second service experience information can be obtained, and the original prediction model is trained according to the label corresponding to the second service experience information and the predicted second target product so as to adjust the parameter values of all the parameters in the original prediction model.
Wherein the predictive model may be a Radial Basis Function (RBF) neural network.
The second service experience information for the prediction model training is very much, and the above operation is performed on each second service experience information, and when the preset convergence condition is satisfied, the prediction model training is completed.
The meeting of the preset convergence condition may be that the loss value determined based on the second target product predicted by the trained prediction model to obtain each piece of second service experience information, the label corresponding to each piece of second service experience information is smaller than a preset loss threshold, or the iteration number of training the original prediction model reaches a set maximum iteration number, etc. The implementation may be flexibly set, and is not particularly limited herein.
As a possible implementation manner, when the original prediction model is trained, the second service experience information may be divided into a training sample and a test sample, the original prediction model is trained based on the training sample, and then the reliability degree of the trained prediction model is verified based on the test sample.
Because the first service experience information of the target account can be obtained in the process of recommending the product information, the first service experience information comprises at least one of age information of the target account, sex information of the target account, hobby information of the target account, experience time information of the target account and experience evaluation information of the target account. After the first service experience information of the target account is obtained, the first service experience information is fully utilized through a pre-trained prediction model, a first target product corresponding to the first service experience information is determined, and then the product information of the first target product is recommended to the target account, so that the product is recommended to the target account more conveniently and quickly, the recommended product is determined based on the service experience information of the target account, the method is more suitable for users to a certain extent, and the matching efficiency and user experience of the product and user requirements are improved.
Example 2:
fig. 2 is a schematic diagram of a training flow of a specific prediction model provided by an embodiment of the present invention, and the following describes a method for training the prediction model provided by the embodiment of the present invention with reference to fig. 2 by using the prediction model as an RBF model:
Firstly, sample service experience information for prediction model training is collected in advance, labels corresponding to the sample service experience information are determined, and any label corresponding to the sample service experience information is used for identifying products purchased by a sample account corresponding to the sample service experience information. And determining a probability value, such as 1, corresponding to the label corresponding to each sample service experience information according to the label corresponding to each sample service experience information.
In order to facilitate the original prediction model to process sample service experience information, each sample service experience information can be cleaned, some useless or invalid information is filtered out, then the original prediction model is trained for convenience, a trained prediction model is obtained, the sample service experience information is preprocessed, the preprocessed sample service experience information is determined to be second service experience information, and then the original prediction model is trained based on the second service experience information, so that the trained prediction model is obtained.
And designing a network structure of an original prediction model, for example, determining a connection mode of the RBF model as p-K-1, namely, p input layer neurons, K hidden layer neurons and 1 output layer neurons of the RBF model, and carrying out random assignment on each parameter value in the original prediction model. Wherein neurons in the hidden layer are smaller natural numbers.
The current iteration number, i.e., the currently saved iteration number +1, is updated before the following steps are performed on the second service experience information for each sample account.
The original predictive model is trained based on the second service experience information for each sample account. Specifically, for the second service experience information of each sample account, the following steps are executed:
inputting the second service experience information into the original prediction model, for example, the second service experience information of a certain sample account input at the t moment is x 1 (t),x 2 (t),…,x p (t) the label corresponding to the second service experience information is y (t) =a i ,A i The product purchased by the sample account can obtain a second target product corresponding to the second service experience information input currently and a probability value recommended to the target account corresponding to the second target product through the original prediction model, wherein the second target product can be expressed as
Specifically, the second target product corresponding to the second service experience information input currently is obtained through the original prediction model, and the second target product can be obtained through the following modes:
for the probability value omega corresponding to the second target product corresponding to the second service experience information x (t) input at the t-th moment k (t) represents the connection weight of the kth neuron in the kth hidden layer and the output layer, k=1, 2, …,K;θ k (x (t)) is the output of the hidden layer kth neuron after the second service experience information x (t) is input to the original prediction model.
Wherein, after the second service experience information x (t) is input into the original prediction model, the output theta of the kth neuron of the hidden layer k The calculation formula of (x (t)) is:
μ k (t) represents the central value, σ, of the kth neuron of the hidden layer at the time t k The central width of the kth neuron of the hidden layer at the t-th moment is represented.
After the second target product is obtained, determining a loss value according to the probability value corresponding to the second target product and the second service experience information x (t) input at the t moment, wherein the loss value is determined specifically by the following method:
wherein E (t) represents a loss value corresponding to the second service experience information x (t) input at the t-th moment, y (t) represents a probability value corresponding to the label corresponding to the second service experience information x (t) input at the t-th moment, the probability value is 1,and a probability value corresponding to a second target product corresponding to the second service experience information x (t) input at the t-th moment.
Based on the determined loss values, the values of the parameters in the original prediction model are adjusted, specifically by the following formula:
Wherein W is T (t)=[w 1 (t),w 2 (t),…,w K″ (t)] T The connection weights of K neurons in the hidden layer at the t time and the output layer respectively are represented, and the t time is represented; eta epsilon (0,0.1)]Representing the neural network learning rate; θ k (x (t)) is the output of the kth neuron of the hidden layer after the second service experience information x (t) is input into the original prediction model;and y (t-1) represents a probability value corresponding to a label corresponding to the second service experience information x (t) input at the t-1 time for the probability value corresponding to the second target product corresponding to the second service experience information x (t) input at the t-1 time.
Through the steps, the original prediction model is trained, whether the current trained prediction model meets a preset convergence condition is judged, and whether the trained prediction model is obtained is determined. Specifically, if the sum of the loss values corresponding to each piece of second service experience information acquired in the current iteration is smaller than a set loss value threshold, determining that a prediction model with completed training is acquired; otherwise, judging whether the current iteration number 1 reaches the maximum iteration number L, if so, stopping continuous training, and if not, continuing training the prediction model.
When the maximum iteration number is set, the maximum iteration number is generally set to be larger, for example, L e (100, 300), so that the sum of the loss values corresponding to each piece of second service experience information acquired by the current iteration is smaller than a set loss value threshold before the current iteration number reaches the maximum iteration number.
By the method, after the trained prediction model is obtained, the accuracy of the trained prediction model can be tested, and after the prediction model is determined to pass the test, the probability value of each product recommended to the target account can be determined based on the obtained first service experience information through the trained prediction model. For each product, if the probability value of the product meets the preset recommendation requirement, determining the product as a first target product and recommending the first target product to a target account; otherwise, the product is not recommended to the target account.
Example 3:
in order to facilitate the model to process the second service experience information, in the embodiment of the present invention, the preprocessing the sample service experience information in the sample set includes:
If the sample service experience information comprises age information of the sample account, determining a preprocessed age value of the sample account based on the age information of the sample account, an average value of the age information of each account for purchasing the product, and a mean square error of the age information of each account for purchasing the product;
if the sample service experience information comprises preference information of the sample account, determining a preprocessed preference value of the sample account for the type of preference based on investigation scores of the sample account for the type of preference and correlation degrees of the preconfigured type of preference and the product.
In the embodiment of the invention, because some information inconvenient for the model to process may exist in the sample service experience information, such as non-numerical experience evaluation information, gender, hobbies and other information of an account, the sample service experience information needs to be preprocessed before being input into the original prediction model, for example, regularization processing is performed on the sample service experience information, punctuation marks in the sample service experience information and cases in unified sample service experience information are deleted, the non-numerical information in the sample service experience information is converted into corresponding numerical values and the like, the preprocessed sample service experience information updates the original sample service experience information, and training is performed on the original prediction model based on the updated sample service experience information, so that the original prediction model is convenient to further process the sample service experience information.
Specifically, for each type of service experience information that may exist in the sample service experience information, the following manner may be used for preprocessing:
in the first aspect, in an actual application scenario, the sample service experience information may include age information of a sample account, so that, in order to enable the prediction model to learn a product and a potential relationship existing between the sample service experience information and the age information of the sample account, in the embodiment of the present invention, if the sample service experience information includes the age information of the sample account, an average value and a mean square error of ages of each account where the sample is purchased in a sample set may be determined for each product. And then, aiming at each sample service experience information in the sample set, carrying out corresponding processing according to the age information of the sample account, the average value and the mean square error of the age information of each account of the product in the label corresponding to the purchase sample service experience information, determining the preprocessed age value of the sample account, and determining second service experience information based on the preprocessed age value of the sample account.
In one possible embodiment, if the sample service experience information includes age information of the sample account, the determining the preprocessed age value of the sample account based on the age information of the sample account, an average value of the age information of each account where the product is purchased, and a mean square error of the age information of each account where the product is purchased includes:
Wherein A is i An ith product purchased for the sample account; c (C) 1 (A i ) Is the pre-processed age value of the sample account; age represents age information of the sample account; c age An average value of age information representing each account for purchasing the ith product; sigma (sigma) age Mean square error of age information representing each account for purchasing the ith product.
In the second mode, in an actual application scene, the sample service experience information may include gender information of the sample account, where the gender is non-numerical information, which is not beneficial to processing of the original prediction model. In order to enable the prediction model to learn the potential relationship between the product and the gender information of the account, in the embodiment of the present invention, if the sample service experience information includes the gender information of the sample account, a first value corresponding to the gender information for a male and a second value corresponding to the gender information for a female may be preset. For each sample service experience information in the sample set, if the sex information of the target account included in the sample service experience information is male, determining a preset first numerical value as a preprocessed sex value of the sample account; and if the gender information of the sample account included in the sample service experience information is female, determining a preset second value as the preprocessed gender value of the sample account.
For example,
wherein A is i Ith product, C, representing sample account purchase 2 (A i ) The method comprises the steps of purchasing a pre-processed sex value corresponding to a sample account of an ith product, determining that the pre-processed sex value of the sample account is-1 if the sex information of the sample account is male, and determining that the pre-processed sex value of the sample account is 1 if the sex information of the sample account is female.
In the third mode, in the actual application scene, the sample service experience information may include the preference information of the sample account, and the preference information is also non-numerical information, which is unfavorable for the processing of the original prediction model. In order to enable the prediction model to learn the potential relation between the product and the preference information of the account, in the embodiment of the invention, the investigation score of each sample account for each type of preference is counted in advance so as to determine the preference degree of the sample account for the type of preference through the investigation score, for example, the investigation score is lambda j =0, indicating that the sample account has no preference for the j-class hobbies; lambda (lambda) j =0.5, indicating that the sample account has a certain preference for the j-class hobbies; lambda of j =1, indicating that the sample account favorites the j types of hobbies, and preconfigured each type of hobbies and each Correlation of products to determine influence of such hobbies on products purchased in sample accounts, such as correlation G of a hobbies with a certain product j =1, which indicates that the association between the preference and the product is strong, and that the preference has a great influence on the purchase of the product in the sample account; if the correlation degree G of the preference and the product j =0.75, which means that the association between the preference and the product is strong, and that the preference has a great influence on purchasing the product in the sample account; if the correlation degree G of the preference and the product j =0.5, indicating that the preference has a certain association with the product, and that like the preference has a certain effect on the purchase of the product by the account; if the correlation degree G of the preference and the product j =0.25, which means that the association between the preference and the product is weak, and that the preference has less influence on purchasing the product in the sample account; if the correlation degree G of the preference and the product j =0, indicating that the preference has no association with the product, and that the preference has no effect on purchasing the product from the sample account.
Specifically, sample service experience information of any sample account in a sample set is obtained, and for each type of preference, a preference value of the sample account after preprocessing of the preference is determined based on investigation scores of the sample account on the preference and correlation degrees of the preconfigured preference and products purchased by the sample account.
Wherein the association degree of each type of hobbies and each product is set according to human experience.
In a possible manner, if the sample service experience information includes preference information of the sample account, the determining, based on the investigation score of the sample account on the preference and the association degree of the pre-configured preference with the product, a pre-processed preference value of the sample account on the preference includes:
C 3j (A i )=λ j G j
wherein A is i An ith product purchased for the sample account; c (C) 3j (A i ) Is the sample account to the j-th hobbiesIs a pre-processed preference value of (a); lambda (lambda) j A survey score representing the sample account for category j hobbies; g j Representing the association degree of the preconfigured jth hobbies and the ith product.
In the fourth aspect, in order to enable the prediction model to learn the potential relationship between the product and the experience time information of the account, in the embodiment of the present invention, if the experience time information of the sample account is included in the sample service experience information, the sample service experience information of each sample account may be determined according to a preset service time period, for example, 8:00-17:00 a day, and the reservation time of each reservation of the sample account, for example, the reservation times of each hour of the sample account in the service time period, for example, 14:30 a sample account has been reserved twice and 14:40 a time, the sample account is reserved for 3 times in the service time period, and the number of hours of each reservation of the sample account is determined, and the reservation time value of the sample account after the pretreatment is determined according to the reservation times of the sample account and the number of hours.
In one possible implementation manner, if the sample service experience information includes experience time information of the sample account, determining the pre-processed reserved time value of the sample account according to the reserved times and the hours includes:
wherein A is i An ith product purchased for the sample account; c (C) 4 (A i ) Is a pre-processed reservation time value for the sample account; m is the reservation times; h is the number of hours.
In the fifth mode, in the actual application scenario, the sample service experience information may include experience evaluation information of the sample account, where the experience evaluation information is also non-numeric information, which is unfavorable for the original experienceThe prediction model is processed. In order to enable the prediction model to learn the potential relationship between the product and the experience evaluation information of the account, in the embodiment of the invention, if the sample service experience information includes the experience evaluation information of the sample account, the corresponding relationship between the experience evaluation information and the experience evaluation information value may be preset. In the implementation process, for each sample service experience information, determining a target experience evaluation information value corresponding to the experience evaluation information of the sample account according to a preset corresponding relation between the experience evaluation information and the experience evaluation information value. For example, C 5 (A i ) =0, 0.5 and 1, c 5 (A i ) And for the target experience evaluation information value corresponding to the experience evaluation information of the sample account, the target experience evaluation information value is 0, which indicates that the sample account experiences dissatisfaction with the secondary service, the target experience evaluation information value is 0.5, which indicates that the sample account experiences satisfaction with the secondary service, and the target experience evaluation information value is 1, which indicates that the sample account experiences very satisfactory with the secondary service.
According to the trained prediction model, because the information of the age, sex, hobbies and the like of the users are different, each service which can be reserved has different attraction to the target accounts of different age groups, different sexes and different hobbies, and further the correlation degree between the finally purchased product of the target account and the times of experiencing the service by the target account is also different, for example, some target accounts experience a certain service for multiple times, the purchase of the product corresponding to the service is determined, some target accounts experience a certain service once, the product corresponding to the service is purchased, even some target accounts reserve a certain service, but the product corresponding to another service is purchased finally. Therefore, based on a large amount of second service experience information, the nonlinear input-output relationship can be learned to a certain extent through the prediction model, and influences on products purchased by accounts among different services, such as a user visiting a memorial park in advance, 30% of users purchase physical examination packages with different dimensions.
Example 4:
in order to accurately determine the first target product, based on the foregoing embodiments, in the embodiment of the present invention, before the obtaining, by the pre-trained prediction model, the first target product corresponding to the first service experience information, the method further includes:
determining a target type of each piece of information in the first service experience information;
if it is determined that the first service experience information lacks information of the necessary information type according to the pre-configured necessary information type and the target type, determining the history information of the lacking necessary information type from the pre-stored history information of each necessary information type of the target account, and adding the history information to the first service experience information.
In an actual application scenario, it may happen that the user does not want to fill in some information that has been filled in when the user reserved for some previous service, for example, information such as name, gender, hobbies, etc., so that there may be a situation that the acquired reserved information is missing, and further, the first service experience information determined based on the reserved information and the experience information of the target account is missing. When the condition that the first service experience information is missing is determined, the fact that the content in the first service experience information is incomplete is indicated, and the first target product cannot be accurately recommended to the target user according to the information contained in the first service experience information. Therefore, in order to ensure that the first target product recommended to the target account is accurately determined, the necessary information types are preconfigured, and for each necessary information type, the historical information of the necessary information type recorded by the target account in the historical experience service process is saved. In the implementation process, before a first target product corresponding to the first service experience information is obtained through a pre-trained prediction model, determining a target type of each piece of information in the obtained first service experience information, then matching the target type with a pre-configured necessary information type, and determining whether the first service experience information has the condition of lacking any necessary information type. If it is determined that the first service experience information lacks information of a necessary information type, the history information of the necessary information type lacking currently can be determined from the pre-stored history information of each necessary information type of the target account and added to the first service experience information, so that subsequent steps can be performed according to the added first service experience information.
If it is determined that the information of the necessary information type is not missing in the first service experience information, a subsequent step may be directly performed according to the currently acquired first service experience information.
It should be noted that, if it is determined that the history information of a certain necessary information type of the target account is not stored currently, in order to ensure that the first target product recommended to the target account is accurately determined later, in the embodiment of the present invention, a prompt message of a necessary information type that supplements the lack of history information, for example, "please input age", may be output, so that the target account further perfects the input first service experience information.
The output of the prompt message of the necessary information type for supplementing the lacking history information may be a voice broadcast of the prompt message of the audio format, for example, voice broadcast of the prompt message of the necessary information type for supplementing the lacking history information, "please input age", or display of the prompt message corresponding to the text form on the display interface, for example, display of the prompt message of the necessary information type for supplementing the lacking history information "please supplement gender". The two modes of outputting the prompt information can be combined at the same time, namely, the prompt information in the audio format is broadcast at the same time and the prompt information in the text format is displayed on the display interface.
The specific selection of which mode to output the prompt message can be preset according to the preference of the user, or can be selected according to the capabilities of the electronic devices, for example, some electronic devices do not have a display interface capable of displaying the prompt message, and when the prompt message is output, the prompt message in an audio format can be broadcasted for the electronic devices.
After the prompt information of the necessary information type for supplementing the lacking historical information is output, the information supplemented by the user can be received, the supplemented information is correspondingly stored with the information type corresponding to the information, and according to the supplemented information and the first service experience information acquired before, a first target product recommended to the target account is determined through a pre-trained prediction model.
Further, when the user reserves the service, the user may input some private information, such as an identification card number, a mobile phone number, etc., and if the private information is revealed, the user's property security may be possibly caused. Therefore, after the first service experience information is acquired, the privacy information in the first service experience information needs to be extracted, and the extracted privacy information is subjected to desensitization. Specifically, the method for desensitizing the private information belongs to the prior art, and is not specifically limited herein.
In order to further facilitate determining a product that can be recommended to the target account, in the embodiment of the present invention, before the obtaining, by the pre-trained prediction model, the first target product corresponding to the first service experience information, the method further includes:
determining a target type of each piece of information in the first service experience information;
and filtering the information of which the target type is not the pre-configured necessary information type in the first service experience information.
In the practical application process, the first service experience information input by the user may contain many other useless contents besides the information of the necessary information type, and the useless contents are generally large and redundant, so that not only are storage resources consumed, but also a large amount of data processing resources are wasted. Therefore, in the embodiment of the invention, in order to further facilitate determining the first target product that can be recommended to the target account, before the first target product corresponding to the first service experience information is obtained through the pre-trained prediction model, filtering the content included in the obtained first service experience information.
In a specific implementation process, a target type of each piece of information in the first service experience information is determined. And then respectively matching each target type with a preconfigured necessary information type, and filtering information corresponding to a target type which is not matched with any preconfigured necessary information type, namely filtering information of which the target type is not the preconfigured necessary information type in the first service experience information, so as to filter useless information in the first service experience information.
Example 5:
fig. 3 is a schematic diagram of a specific product information determining process provided by an embodiment of the present invention, and a detailed description will be given of a product information method provided by an embodiment of the present invention with reference to fig. 3:
the user makes service reservations on the product recommendation system.
Specifically, the user can carry out reservation services for visiting an old community, visiting a memorial park, visiting an oral cavity mechanism, visiting a physical examination mechanism, carrying out psychological consultation experience and carrying out green medical experience on the C-end APP of the product recommendation system. According to the service, the user can enjoy the experience in advance, so that the user experience is improved, and different products are provided for the user in a targeted manner according to the actual experience and evaluation of the user.
And acquiring sample service experience information.
In the specific implementation process, the product recommendation system mainly comprises a product center, a resource center and 3 business center stations of an order center, wherein the product center is responsible for managing products and service items sold on line and standardizing the products; the resource center is used for scheduling personnel, equipment, places and the like for providing services, and carrying out on-line management on the resources, so that on-line reservation of users is facilitated, and the utilization rate of the resources is improved; the order center stores reservation information input based on the account and service experience information determined by the experience information.
The persistent layer in the order center synchronizes the service experience information stored in the Mysql database and the mongoDB database to a distributed Search (es) data center in real time, and finally stores the service experience information in the es data center. The scheme for synchronizing the service experience information stored in the Mysql database to the es data center is as follows:
the canaal real-time synchronizer is deployed as a slave to the Mysql database, reads the log data binlog, and sends updates to the table data in the Mysql database to the kafka message center in the format of a structured json.
Because the service experience information stored in the Mysql database is stored in the es data center in real time, the data standardization requirement is high, the kafka information is directly stored in the es, the data processing difficulty is high, and the maintenance is difficult. Therefore, in the embodiment of the invention, the message data in the kafka message center is not directly stored in the es data center, but the message of the kafka message center is subscribed through a micro service for consuming the kafka message, so that the real-time performance of the message is ensured, and the service experience information can be flexibly processed. When the kafka message is consumed, the kafka message can be personalized according to different service types.
In the embodiment of the invention, a main and standby cluster mode is adopted for cluster construction of the es data center, for example, the main cluster is 3 es data center main nodes and 5 es data center data nodes. The standby cluster is also 3 es data center main nodes and 5 es data center data nodes, and when the main cluster provides different services, the standby cluster is automatically started.
After the service experience information stored in the Mysql database is stored in the es data center, a rest api interface enabling product is provided based on the capability of fast indexing of the es full text and is used as an input parameter of predictive model training.
The scheme for synchronizing the service experience information stored in the mongoDB database to the es data center is as follows:
at present, there are various ways to synchronize data stored in the mongoDB database to the es data center, and the service can be synchronized through the web server, and the service is written to the es data center and the mongoDB database, but this way has a great expenditure on the server, and once the data is stored, the data consistency is affected. Buffer inputs in logstack can also be utilized by adding mongo input and ES output plug-ins, but this approach is very dependent on Java database connectivity (JDBC). Therefore, in the embodiment of the invention, a mongo-connector mode can be adopted, the tool synchronizes data between the mongo db and the es data center, tracks the operation log data oplog of the mongo db, and can also perform real-time synchronous operation on the data stored in the es data center when the operation on the data in the mongo db is kept.
In the implementation process, firstly, starting a copy set mode of the mongoDB, setting a copy set name, and initializing and verifying the state of the copy set.
The method comprises the steps of configuring an es data center, setting the es data center of a mongoDB database connected through a mongoconnector, and specifically determining the ip and port of the mongoDB database and the information of an es data center cluster.
And verifying that the service experience information is updated in the mongoDB database, and inquiring whether corresponding data changes or not by the es data center.
And determining service experience information stored in the es data center as sample service experience information, preprocessing each sample service experience information, such as cleaning, desensitizing and the like, determining the preprocessed sample service experience information as second service experience information, training an original prediction model based on each second service experience information, and judging whether the current trained prediction model meets a preset convergence condition or not, thereby determining whether the trained prediction model is acquired.
If the current trained prediction model meets the preset convergence condition, the trained prediction model is determined to be obtained, the trained prediction model is output, and the first service experience information is obtained based on the method in the embodiment. And determining a first target product corresponding to the first service experience information based on the first service experience information through the trained prediction model, so that the product information of the first target product is recommended to a target account.
Based on age information of a target account, sex information of the target account, hobby information of the target account, experience time information of the target account and experience evaluation information of the target account, analysis training is carried out by combining a product finally purchased by the target account, a neural network prediction model is established, intelligent product recommendation is carried out based on the model, namely, a first target product which is more suitable for the target account is provided for the target account in a targeted manner based on first service experience information of the target account through the prediction model which is completed through training.
In order to further improve accuracy of the first target products recommended to the target account, before recommending the product information of the first target products to the target account, each determined first target product may be sent to a relevant staff member, so that accuracy of each first target product may be screened through experience of the relevant staff member. When the relevant staff member determines that a certain first target product is suitable for being recommended to the target account, determination information of the first target product can be input. After receiving the determination information of the first target product, the electronic device for determining product information recommends the product information of the first target product to the target account. When the related staff member determines that a certain first target product is not suitable for being recommended to the target account, the determination information of the first target product can not be input, or error information for determining the first target product can be input, so that the product information of the first target product is not recommended to the target account later.
