Wherein the data collection device 102 communicates with the server 104 via a network. The data acquisition device can be a plurality of devices. The data collection device 102 collects report query behavior data of a user to be predicted, and sends the collected data to the server 104. The server 104 acquires the business behavior data of the business user, aggregates the report query behavior data and the business behavior data to obtain user behavior topic data, and inputs the user behavior topic data into a pre-trained behavior prediction model to obtain a behavior prediction result corresponding to the user to be predicted. The data collection device 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, and tablet computers. The server 104 may be implemented as a stand-alone server or a server cluster comprised of multiple servers.
In one embodiment, as shown in fig. 2, a user behavior prediction method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
step 202, report query behavior data of the user to be predicted is obtained.
The user to be predicted refers to a user with a report query behavior. The report query behavior data refers to a query record generated by report query behavior of a user to be predicted.
Specifically, the server obtains report query behavior data collected by the data collection device. The user can freely inquire the credit report of the user through a plurality of preset self-service channels so as to know the credit condition of the user. Therefore, the query records generated by the report query behavior of the user to be predicted can be collected through the data collection devices corresponding to the auxiliary channels respectively to serve as report query behavior data. The plurality of self-service channels can be obtained from preset application programs and self-service equipment. The report query behavior data may include query time, query mode, location area to which the user belongs, user basic information, and other data.
Step 204, acquiring service behavior data of the service user.
The service user refers to a user transacting a service in a financial institution. The service behavior data refers to service data related to service users.
The server can also obtain business behavior data from various business data sources such as a business application system, a business database, a business application log and the like, wherein the business behavior data can comprise user basic information, resource conversion data between the user and a financial enterprise, user credit score data, contract data, resource conversion channel data and external market data. For example, the transaction may include a loan transaction, a financial transaction, and the like. The resource conversion data may be transaction data.

And step 206, aggregating the report query behavior data and the service behavior data to obtain user behavior theme data.
The aggregation processing refers to integrating and extracting scattered report query behavior data and business behavior data. The user behavior theme data refers to aggregated data taking user behaviors as themes.
The server integrates the acquired report query behavior data and the acquired business behavior data, and specifically, the report query behavior data and the business behavior data can be divided into relational data and non-relational data, and the relational data and the non-relational data are integrated respectively to obtain integrated data. Relational data refers to data that is structured, such as data that can be used to generate tables. Non-relational data refers to unstructured data, such as textual information. And extracting resource data from the integrated data as user behavior topic data. The resource data refers to data assets, and may include user characteristic data and statistical index data.
Alternatively, the user behavior topic data may be a user behavior topic aggregation table.
And 208, inputting the user behavior theme data into a pre-trained behavior prediction model to obtain a behavior prediction result corresponding to the user to be predicted.
The behavior prediction result refers to the probability that the user to be predicted purchases products of each product category.
The server is stored with a behavior prediction model in advance, and the behavior prediction model is obtained by training a large amount of user report query behavior data and user service behavior data.

For example, the behavior prediction model may include, but is not limited to, BERT (pre-trained language characterization model), convolutional Neural network model (CNN), and Random Forest model (RF).
The server calls a pre-trained behavior prediction model, user theme behavior data are input into the behavior prediction model, and the probability that the user to be predicted purchases products of each product category is predicted according to the user behavior theme data through the behavior prediction model. For example, product categories may include funds, insurance, and deposits. The behavior prediction result corresponding to the user to be predicted may include a probability of purchasing a fund product of 85%, a probability of purchasing an insurance product of 70%, and a probability of purchasing a deposit product of 50%.
Furthermore, the server can screen target users according to the user behavior theme data, wherein the target users refer to potential users who have not transacted business in the financial enterprise, and therefore customer obtaining channels are increased.
The user behavior prediction method comprises the steps of obtaining report inquiry behavior data of a user to be predicted, obtaining service behavior data of a service user, carrying out aggregation processing on the report inquiry behavior data and the service behavior data, inputting user behavior subject data obtained through aggregation into a pre-trained behavior prediction model, and obtaining a behavior prediction result corresponding to the user to be predicted. By acquiring the report query behavior data of the user, the behavior prediction data of potential users and low-end users are enriched, and the behavior prediction of the user can be performed under the condition of lacking of resource conversion data. The report query behavior data and the service behavior data are aggregated, so that the implicit value of the data is mined, and then the user behavior is predicted through the behavior prediction model, so that the accuracy of behavior prediction is improved.
In one embodiment, obtaining report query behavior data of a user to be predicted comprises: acquiring report query behavior data of a user to be predicted from a plurality of self-service channels; the plurality of self-service channels comprise preset application programs and self-service equipment.

Reporting query behavior data may also be referred to as query logs or query logs. For example, the preset application program may be a personal internet bank, a personal cell phone bank, or the like. The self-service device may be a website intelligent teller machine.
Specifically, by embedding a data collection SDK (Software Development Kit) in a preset application program, when a user queries a report through a prediction application program, the SDK can record each query log of the user in real time, so that the data collection device obtains the query logs of the user collected by the SDK. Meanwhile, the query log on the user self-service equipment can be acquired through the data acquisition equipment corresponding to the self-service equipment.
In the embodiment, the report query behavior data of the user to be predicted is acquired from a plurality of channels such as the preset application program and the self-service device, so that the integrity and comprehensiveness of the report query behavior data are improved, and the behavior prediction accuracy is improved.
In an embodiment, as shown in fig. 3, aggregating the report query behavior data and the service behavior data to obtain the user behavior topic data includes:

After the big data platform obtains data of a plurality of data sources of report query behavior data and business behavior data, a data extraction process is started through an ETL tool, the report query behavior data and the business behavior data are extracted to an intermediate layer, then a data conversion process is started, data conversion is carried out on the data of the intermediate layer, and the data conversion process can comprise cleaning, conversion and loading. Because the acquired report query behavior data and the acquired service behavior data are both original data, redundancy, conflict, abnormality and deficiency exist, and data conversion needs to be carried out through a big data platform. Specifically, the data conversion process may include performing data cleaning on the acquired report query behavior data and the acquired business behavior data through an ETL tool, and the data cleaning manner may include uniform data expression format, sorting data, screening duplicate data, merging or dividing data items, invalid data deletion, missing column deletion, missing value replacement, abnormal value processing, row deduplication, column deduplication, code replacement, data filtering, type conversion, and format conversion. And storing the cleaned data into the ODS. And then, carrying out data conversion on the data cleaned in the ODS through an ETL tool to obtain effective query behavior data and effective service behavior data. The data conversion mode may include performing data conversion on the cleaned data according to a preset conversion rule. For example, the preset conversion rules may include adding sequences, adding constants, line-column conversion, merging records, data item splicing, data item splitting, data type conversion, character string replacement, character string padding, character string clipping, character string truncation, numerical extraction, numerical padding, value mapping, computation function conversion, script execution, data set splitting, data set merging, data set joining, data set sorting, and the like. The valid query behavior data and the valid business behavior data are stored in a data repository, i.e., the business data repository in fig. 4. The business data warehouse can perform data calculation according to the model and the database and the data calculation flow, and can also perform data summarization according to the model and the database and the data summarization flow. And then starting a converted data loading process through an ETL tool, loading effective query behavior data and effective business behavior data in a data warehouse, and performing relational data integration and non-relational data integration on the effective query behavior data and the effective business behavior data, so as to extract resource data from the integrated data to be used as user behavior theme data. The resource data refers to data assets, and may include user characteristic data and general statistical indicator data with sharing reusability. The user characteristic data may include user profile characteristics such as the user's age, income level, occupation, etc., or may also include product attribute characteristics such as product type, product price, etc. The general statistical indicator data may indicate data categories such as user basic information indicators, resource conversion indicators, credit score indicators, and the like.

In one embodiment, inputting the user behavior topic data into a pre-trained behavior prediction model, and obtaining a behavior prediction result corresponding to a user to be predicted includes: inputting user behavior theme data into a pre-trained behavior prediction model, and performing prediction operation on the user behavior theme data through the behavior prediction model to obtain the relevance between report inquiry behavior data and service behavior data; and predicting a behavior prediction result corresponding to the user to be predicted according to the relevance through a behavior prediction model.
The service behavior data refers to service data related to service users.
A plurality of important factors of business behavior data are deployed in the pre-trained behavior prediction model. For example, the behavior prediction model may be any one of a BERT model, a convolutional neural network model, and a random forest model.
Specifically, by means of a behavior prediction model, concurrent calculation is performed on important factors of user characteristic data and business behavior data in user behavior theme data by means of multiple threads, and the relevance between report query behavior data and business behavior data is obtained, so that the probability that a user to be predicted purchases products of each product category is determined according to the calculated relevance between the report query behavior data and the business behavior data. Wherein the greater the value of the association, the higher the probability of purchasing a product of the corresponding product category.
In this embodiment, the server can effectively analyze the relevance between the report query behavior data and the business behavior data according to the user behavior topic data. Meanwhile, the prediction efficiency of the behavior prediction result can be improved through multi-thread concurrent computation.
In one embodiment, the method further comprises: determining the target product type according to the behavior prediction result; determining a target product corresponding to the target product category in preset category products; and pushing the target product to a user to be predicted.

In this embodiment, a target product category is selected from a plurality of product categories of the behavior prediction result, a target product corresponding to the target product category is determined in a preset category product, and pushing is performed, so that the pushing range can be further narrowed, the product pushing is more accurate, the user requirements can be better met, and the user conversion rate and the user retention rate can be improved.
In one embodiment, before inputting the user behavior topic data into the pre-trained behavior prediction model, the method further comprises: classifying users to be predicted according to the user behavior theme data to obtain user categories corresponding to the users to be predicted; determining a target user in the users to be predicted according to the user category and a preset screening condition; extracting target subject data corresponding to a target user from the user behavior subject data; inputting the user behavior theme data into a pre-trained behavior prediction model, and obtaining a behavior prediction result corresponding to a user to be predicted comprises the following steps: and inputting the target subject data into a pre-trained behavior prediction model to obtain a behavior prediction result corresponding to the target user.
User characteristic data is included in the user behavior theme data, and the user characteristic data can include user portrait characteristics such as the age, income level, occupation, location area where the user is located and the like of the user, or can also include product attribute characteristics such as product type, product price and the like. The server can classify the users to be predicted according to the user characteristic data in the user behavior theme data, and classify the users to be predicted containing the same characteristic data into a user category. Therefore, the user category corresponding to the user to be predicted may be one or more. For example, user categories may include 20-30 years of age, moderate income level, free occupation, living in Beijing, and the like. And determining a target user in the users to be predicted according to the user category and the preset screening condition. Wherein the predetermined screening condition may be an age of 25-35 years, income level and stable occupation.

The behavior prediction mode of the target user is the same as that of the user to be predicted, and details are not repeated here.
In the embodiment, the users to be predicted are classified according to the user behavior theme data to obtain the user categories corresponding to the users to be predicted, the target users are further determined, the target users are pushed, real target users can be screened from a large number of users to be predicted, and the product pushing accuracy can be improved.
In one embodiment, the method further comprises: and sending the user behavior theme data to a data analysis terminal to instruct the data analysis terminal to carry out risk prediction on the user to be predicted according to the user behavior theme data.
Specifically, the data analysis terminal may obtain the query times of the report query behavior data in the user behavior topic data, and when the query times meet a preset condition, it indicates that the user to be predicted is in an abnormal state. The preset condition may be that the number of queries within a preset time period is exceeded. For example, the number of queries exceeds 5 times a day. The data sources of the user credit risk assessment are increased by analyzing the report query behavior data, and the monitoring of the abnormal query behavior of the user is realized, so that the attention to the user credit risk is strengthened.
Furthermore, the data analysis terminal can also determine users who have transacted business, such as users in post-loan management, according to the user behavior topic data. And performing credit verification on the transacted user to predict the risk early warning level of the user. Specifically, each risk early warning level may correspond to one credit assessment score data interval. The credit verification may be to acquire user credit score data of the handled service, compare the user credit score data with a plurality of preset risk early warning levels for credit assessment score intervals, and determine the risk early warning level as a risk early warning level corresponding to the user having handled the service when the user credit score data falls into the credit assessment score interval corresponding to the risk early warning level. Therefore, the server can generate early warning prompt information according to the risk early warning level and send the early warning prompt information to the associated terminal, and the associated terminal can take risk processing measures for corresponding users according to the received early warning prompt information so as to avoid the influence of overlarge user risk on financial enterprises.
In one embodiment, when the report query behavior data shows no report, it indicates that the credit data of the user cannot be acquired, and the report query behavior data is useless for user behavior prediction at this time, but on the other hand, a data analyzer corresponding to the data analysis terminal knows that the behavior prediction accuracy of the user without the report needs to be improved in other ways.
Exemplarily, as shown in fig. 6, it is a schematic flowchart of a user behavior prediction method in another embodiment.
