Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
As shown in fig. 1, a service recommendation method is provided, and the method includes:
step 102, obtaining a service to be recommended, and determining an initial user portrait corresponding to the service to be recommended, wherein the initial user portrait comprises: a plurality of user features.
The service to be recommended is a service to be promoted, for example, a cloud storage service is a video monitoring service which can be provided for a user by an operator, for example, based on a video uploaded to a cloud, the user can be assisted to monitor whether an old person or a child in a home falls or not, and the like. The service to be recommended is a new service, a corresponding audience is assumed at the beginning of recommendation, and since the service to be recommended is a new service and has no corresponding reference data, an initial audience is assumed in advance, that is, an initial user portrait is set, for example, the initial user portrait is set as follows: the family is the 22-52 age group of the elderly or children.
Step 104, obtaining an initial user group meeting the initial user portrait, including: obtaining user information, wherein the user information comprises: user gender, user age, region where the user is located, and associated card information; when the associated card exists, positioning information corresponding to the associated card is obtained, and identity information corresponding to the associated card is determined based on the positioning information; determining a corresponding user tag according to the identity information corresponding to the associated card, and adding the user tag into the user information to obtain the completed target user information; an initial user population satisfying the initial user representation is determined based on the completed target user information.
In which, the user needs to register real name when handling telecommunication service, for example, handling SIM card and the like needs to fill in real name registration information, so the user information can be obtained from the system. The user information includes: the user gender, the user age, the region where the user is located and whether the associated card exists under the name or not, and the associated card refers to other cards which are associated with the main card, such as a subsidiary card. The method comprises the steps of obtaining positioning information corresponding to the auxiliary card, determining an activity track of the auxiliary card user, deducing the identity of the auxiliary card user according to the activity track, wherein the identity is deduced to be a student if the activity track is frequently in a school, and deducing the identity to be an old person if the activity track is frequently in an old person activity center. After the identity information of the auxiliary card is analyzed, the corresponding user tag is determined to be added into the user information, so that the completed target user information is obtained.
Step 106, obtaining target user information and historical behavior data of the users in the initial user group, and determining a recommendation scheme based on the target user information and the historical behavior data, wherein the historical behavior data comprises: data of which services have been purchased historically, and events and time points that trigger the purchase of the corresponding services.
Wherein, in the initial user group, a part of users have historical behavior data, and the recommendation of the part of users has referenceable historical behavior data, so that the part can be used for determining a recommendation scheme based on target user information and the historical behavior data in the same way as other recommendation modes based on big data. The historical behavior data in the power grid domain mainly include: what packages, traffic usage, package usage, what value added services, and trigger events and time points corresponding to each purchase of the corresponding services are historically purchased. For example, when the user's traffic is fast, the system automatically recommends a traffic package to the user, and then if the user purchases the recommended traffic package, the user records the corresponding trigger event and time point accordingly.
And step 108, transmitting the recommendation information of the service to be recommended to the initial user group based on the recommendation scheme, and extracting the user group characteristics with positive feedback and the user group characteristics with negative feedback for the recommendation information.
The recommendation information can be summary information or link information, and it can be determined which users are positively fed back users and which users have negatively fed back users by collecting whether the users click on the recommendation information. The positive feedback and the negative feedback are opposite, for example, if the user clicks the recommendation, the positive feedback is marked, and if the user clicks the recommendation, the negative feedback is marked, and if the user purchases the recommendation, the positive feedback is marked, and if the user purchases the recommendation, the negative feedback is marked. The rules of positive feedback and negative feedback can be customized in advance for different services.
Step 110, determining group difference features and group common features according to the group features of the user group with positive feedback and the group features of the user group with negative feedback, wherein the group features are extracted based on target user information.
After the user group with positive feedback is obtained, extracting group characteristics of the user group, wherein the group characteristics are extracted based on user information, namely, analyzing the user characteristics of the user group with positive feedback and the user characteristics of the user group with negative feedback, and then finding out group difference characteristics, wherein the group difference characteristics are important characteristics for determining whether a user is interested in recommended content or not.
And step 112, adjusting the user characteristics and the characteristic weights in the initial user portrait according to the group difference characteristics and the group common characteristics to obtain the target user portrait.
The group difference features are difference features corresponding to positive feedback and negative feedback, and part of the difference features are important features for determining whether a user is interested in recommended service or not, so that the part of the difference features need to be enhanced, and then the common features are features of both positive feedback and negative feedback, which indicate that the feature is not a main factor affecting the user, and the weights of the part of the difference features can be adjusted downwards. For example, what we initial user portrayal might set is
After the recommended feedback is obtained, the user in the age group 22-52 with old people or children may find out whether the old people or children in the family are important features for determining whether to purchase or not, and the age group or area is important features for determining whether to purchase or not, so that the initial user portrait can be adjusted to the target user portrait in the age group 22-52 and XX area.
Step 114, determining a target user group corresponding to the target user image, and recommending the service to be recommended to the target user group.
The target user portrait can be accurately recommended based on the finally determined target user group, so that accurate marketing is realized.
According to the business recommendation method, firstly, an initial user portrait corresponding to a business to be recommended is determined, an initial user group is determined based on the initial user portrait, in order to accurately determine the initial user group, target user information is obtained through analysis and perfection of user related information, the initial user group is determined based on the completed target user information, a recommendation scheme is determined according to the target user information and historical behavior data of the initial user group, group difference characteristics and group common characteristics are determined by extracting group characteristics of the user group with positive feedback and group characteristics of the user group with negative feedback, the user characteristics and characteristic weights in the initial user portrait are adjusted based on the group difference characteristics and the group common characteristics, the target user group corresponding to the target user portrait is determined, and business recommendation is further carried out on the target user group. For the problem of insufficient data cold start, the initial user portrait is recommended firstly, then the initial user portrait is adjusted based on recommendation feedback so as to obtain the target user portrait, and the user group requiring the service can be accurately found by the mode, so that the accurate recommendation is realized, and the problem of inaccurate recommendation caused by insufficient data in cold start is solved.
In one embodiment, the business recommendation method is applied to a user operating marketing system which can provide more powerful micro-service architecture support by introducing Spring Cloud. Spring Cloud is an open source framework for building a distributed system, is based on Spring Boot, and provides numerous Cloud native components and tools, such as service registration and discovery, load balancing, circuit breakers, configuration management, etc., to help build highly available, scalable distributed applications.
In addition, the system adopts MySQL system, which is a common relational database management system and can be used for storing user data and task information. MySQL has good performance and reliability, supporting high concurrency access and complex query operations. Through reasonable database design and optimization, efficient management and access of the system to the user data can be ensured.
In building a user operated marketing system, the introduction of the XXL-Job framework may provide support for task scheduling and distributed task execution. XXL-Job is an open-source distributed task scheduling platform and has the characteristics of simplicity, easiness in use, high reliability and high performance. The method is developed based on Java language, and is suitable for various task scheduling scenes including timing tasks, timing scheduling, data processing and the like.
The following effects can also be achieved through the user operation marketing: firstly, the user touch is diversified, namely, the user touch of various modes such as short messages, mails, push notifications, telephone outside calling robots and the like is realized through integrating APIs of third-party service providers, and the marketing information is ensured to be accurately and timely transmitted to the users. Secondly, the task management is efficient, namely a task management module is established, the creation, the scheduling, the execution and the monitoring of the task are realized, and the task processing efficiency and the response speed are improved through technical means such as asynchronous execution, queues and schedulers. And thirdly, the data management is refined, namely, a user image module is designed, basic information, behavior data and the like of a user are collected and analyzed, so that accurate user insight and personalized marketing strategies are provided for marketing teams, and the marketing effect is improved.
In one embodiment, the initial user population comprises: the system comprises a first user group and a second user group, wherein the first user group refers to a user group corresponding to historical behavior data in an initial user group, and the second user group refers to a user group without the historical behavior data in the initial user group;
the step of sending the recommendation information of the service to be recommended to the initial user group, and extracting the user group characteristics with positive feedback and the user group characteristics with negative feedback for the recommendation information, comprises the following steps:

acquiring a second user group without historical behavior data in the initial user group, and determining a recommendation scheme corresponding to the second user group based on the group difference characteristics;
and extracting the user group characteristics with positive feedback and the user group characteristics with negative feedback in the second user group.
In order to make the recommendation more accurate, when recommending the initial user group, the initial user group is divided into a first user group and a second user group, wherein the first user group has referenceable historical behavior data, and the second user group has no historical behavior data. Since the second user population is free of historical behavior data, the recommendation cannot be determined based on the historical behavior data. In order to make the recommendation of the second user group more accurate. Firstly, feedback of a first user group is obtained, and after group difference characteristics are obtained, a corresponding recommendation scheme is matched for a second user group based on the group difference characteristics. By the method, accurate recommendation can be better performed for the second user group, and the problem of recommendation for new users is solved.
In one embodiment, the obtaining the target user information and the historical behavior data of the user of each user in the initial user group, and determining the recommendation scheme based on the target user information and the historical behavior data includes:

extracting group characteristics of each first sub-user group, and determining a first recommendation scheme corresponding to the corresponding first sub-user group based on the group characteristics, wherein the first recommendation scheme comprises the following steps: recommending a document, recommending a mode, recommending time and dynamically filtering a user mode;
receiving recommendation feedback of the first sub-user group;
the determining the group difference characteristic and the group common characteristic according to the group characteristic of the user group with positive feedback and the group characteristic of the user group with negative feedback comprises the following steps:
obtaining sub-population difference characteristics according to the population characteristics of the user population with positive feedback and the population characteristics of the user population with negative feedback in the first sub-user population;
determining sub-population difference characteristics corresponding to each first sub-user population;
The obtaining a second user group without historical behavior data in the initial user group, and determining a recommendation scheme corresponding to the second user group based on the group difference features comprises the following steps:
classifying the second user group based on a plurality of the sub-group difference features, and determining corresponding recommendation schemes based on classification results.
The method comprises the steps of dividing a first user group into a plurality of first sub-user groups, determining a first recommendation scheme corresponding to each first sub-user group, receiving recommendation feedback after recommendation, and extracting difference features according to positive feedback and negative feedback after recommendation to obtain corresponding sub-population difference features, so that the sub-population difference features corresponding to each first sub-user group are obtained. And carrying out matching classification on the second user group and each sub-group difference characteristic, and then determining a corresponding recommendation scheme according to a matching classification result.
Specifically, after the group difference feature is obtained, the second user group and the group difference feature can be matched, the matching degree is calculated, and if the matching degree is larger than a preset value, a recommendation scheme corresponding to the group difference feature is adopted. Each first sub-user group corresponds to a group difference feature. Specifically, the second user population is classified based on a plurality of sub-population difference features, and a corresponding recommendation scheme is determined based on the classification result.
As shown in fig. 2, in one embodiment, the extracting the population feature of each first sub-user group, and determining, based on the population feature, a first recommendation corresponding to the corresponding first sub-user group, where the first recommendation includes: recommending documents and recommending modes, including:
step 112A, obtaining service characteristics of the service to be recommended.
The service features refer to features corresponding to the service to be recommended, and include: the applicable scenario of the service, the service type, and the service purpose.
And step 112B, taking the group characteristics and the business characteristics as the input of a marketing scheme model, and obtaining the marketing characteristics output by the marketing scheme model, wherein the marketing scheme model is obtained based on the marketing data training corresponding to the history recommended business.
The marketing scheme model is obtained by training based on marketing data corresponding to a history recommendation service in advance, and the marketing data corresponding to the history recommendation service comprises: business characteristics, corresponding user groups and obtained marketing characteristics with forward feedback. The marketing features include: characteristics of the document preferred by the user and a document recommendation mode preferred by the user.
And step 112C, obtaining a corresponding first recommendation scheme according to the marketing feature matching.
Different marketing features correspond to different recommended schemes, and the recommended schemes can be determined according to the preset corresponding relation between the marketing features and the recommended features after the marketing features are obtained.
The corresponding marketing characteristic can be obtained by utilizing the marketing scheme model obtained through training according to the group characteristic and the business characteristic, and the corresponding recommendation scheme is obtained based on marketing characteristic matching, so that the determination of the recommendation scheme is time-saving, labor-saving, accurate and reliable.
As shown in fig. 3, in one embodiment, the classifying the second user group based on the plurality of the sub-population difference features, and determining the corresponding recommendation scheme based on the classification result includes:
step 302, obtaining sub-population difference characteristics corresponding to each first sub-user population;
step 304, extracting a second user characteristic of each user in the second user group;
and 306, calculating the coincidence degree between the second user characteristic and each sub-population difference characteristic, taking a first sub-user population corresponding to the sub-population difference characteristic with the highest coincidence degree as a population matched with the user, and taking a corresponding first recommendation scheme as a first recommendation scheme of the user.
The sub-population difference features are features which can reflect whether a user is willing to purchase or not, the sub-population difference features with highest coincidence degree are determined by comparing the coincidence degree of the second user features and each sub-population difference feature, then the first user population corresponding to the sub-population difference features is used as the most matched population of the user, and the first recommended scheme corresponding to the most matched first user population is correspondingly used as the first recommended scheme of the user. In this way, the most suitable recommendation scheme can be matched to the second user group without historical behavior data, so that the recommendation effect is improved.
