[0048] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0049] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0050] Figure 1 It is a flow chart of the online pre-approval method for housing loans provided in an embodiment of the present application. This embodiment can be applicable to elderly care services. The method can be executed by the online pre-approval device for housing loans provided in an embodiment of the present application. The device can be implemented by software and / or hardware and can be integrated into electronic devices such as smart terminals.

[0051] like Figure 1 As shown, the online pre-approval method for the mortgage includes:

[0052] S110, obtaining the lender's declared information, and executing the preset risk rules to determine whether the declared information meets the rule standards.

[0053] Among them, the lender is the person who makes a loan request, that is, the person who needs a loan to buy a house. The declared information can be the basic information of the lender himself, such as name, gender, age and place of origin, etc. It can also include other information, such as whether there is a loan record, whether it is repaid on time, etc. The risk rule can be in the form of a collection, which can include various risk review rules. The risk rule is a strategy rule generated based on business experience and data analysis. It can inform the customer whether it meets the basic access conditions in the early stage of the process, and can generate prompts for users to supplement the materials offline according to the prompts. Among them, the basic access conditions can include whether the documents are complete and whether the information is authentic.

[0054] In this embodiment, optionally, the declared information includes at least one of customer information, liability information and asset information.

[0055] Among them, customer information can include basic information and behavioral information. Basic information includes customer personal information, basic information within the bank, etc. Behavioral information can include offline behavior and terminal behavior, etc. Liability information can include credit card information and loan information, etc. Among them, credit card information includes: account information, usage, repayment status, and overdue status, etc. Loan information can include credit loans, mortgages, car loans, mortgage loans, other loans, such as decoration loans, travel loans, etc. Asset information can include investment information, financial information, deposit information, payment information, and insurance information. After authorization by the customer, the customer's internal and external bank data can be obtained, and the relevant data can be associated, integrated, and cleaned to leave a valid data set. The characteristic information mainly covers the following table:

[0056]

[0057] After the basic feature information is collected, it is necessary to derive the features to form the feature fields required for various modeling and risk control strategies. The feature derivation methods can include transparent transmission, statistical aggregation, and feature cross-talk.

[0058] For numeric fields, when a sample has only one record, such as age, education, etc., it can be directly transparently transmitted as a model input feature. For categorical variables, if there are too many types, you can merge the types and then transparently transmit them, such as student major, company type, occupation, etc., and then transparently transmit them.

[0059] Statistical aggregation is for data of flow or detail types, such as loan details, transaction flow, payroll records, etc. Each person may have multiple flow records occurring at different times. For such flow characteristics, different time windows are usually divided to calculate statistical variables within each window, such as calculating the sum, mean, quantile, minimum, maximum, and standard deviation for numeric fields. For categorical variables, the number of occurrences of the main types and the types of occurrences are calculated.

[0060] Feature crossover is a multi-dimensional crossover between features. Combining the above two methods, more features can be derived. Usually, a categorical variable and a numerical variable are combined to perform statistical aggregation on numerical variables in different categories. For example, by combining the two fields of loan type and loan balance, fields such as car loan balance, mortgage balance, and consumer loan balance can be derived.

[0061] In this solution, optionally, after determining whether the declared information meets the rule standard, the method further includes:

[0062] If it does not meet the requirements, the lender will be notified to provide additional information offline.

[0063] Among them, if the risk rule review finds that the lender's declared information does not meet the preset rule standards, a prompt message can be generated based on the reason for non-compliance to notify the lender to supplement the information offline. Through such a setting, the lender can be automatically reminded to supplement the information during the entire pre-approval stage, avoiding manual intervention and reducing the workload of the staff.

[0064] In this embodiment, optionally, before executing the preset risk rule to determine whether the declared information meets the rule standard, the method further includes:

[0065] Determine whether there are any co-lenders;

[0066] If yes, obtain the loan information of the loan co-lender;

[0067] Accordingly, the preset risk rules are executed to determine whether the declared information meets the rule standards, including:

[0068] The preset risk rules are executed on the declared information of the lender and the participating information of the co-borrower to determine whether the declared information meets the rule standards.

[0069] Among them, the co-borrower can be a person who takes out a loan together with the lender, such as the spouse of the lender, who can be a co-borrower for the mortgage. The co-borrowing information here can be similar to the declared information, such as the co-borrower's basic information, behavioral information, credit card information, loan information, and investment information and financial management information in the asset information. In the case of co-borrowers, the declared information and the co-borrowing information can be simultaneously reviewed according to the risk rules. The advantage of this setting is that when there are co-borrowers, the preset risk rules can be reviewed together based on the declared information and the co-borrowing information, and the review results can be obtained. There is no need to re-review the co-borrowers in other ways, which improves the execution efficiency of this plan and reduces the complexity of the plan implementation.

[0070] Understandably, among the numerous data features, relatively important features can be sorted out, such as the minimum available credit limit for credit cards in the past 30 days, the down payment amount for real estate, the maximum difference in months between the loan due date and the application time, the number of reasons for all types of inquiries from the People's Bank of China, the number of reasons for all types of loan approval inquiries from the People's Bank of China, the average total credit limit for People's Bank of China loans, and the number of overdue loans from the People's Bank of China.

[0071] In this solution, the risk rule engine deploys policy rules generated based on business experience and data analysis, which can inform customers early in the process that they do not meet the basic entry requirements and allow them to supplement their materials offline according to the prompts.

[0072] The content of the rules is mainly set with reference to the following three aspects: blacklist, such as: the applicant hits the bank's blacklist, the applicant hits the list of persons involved in litigation and dishonest debtors; product access conditions that can be judged by the system, such as: the customer is engaged in a restricted industry or the customer is in a restricted area, the customer's outstanding loan balance in the bank is > N yuan; rules derived from business experience and data analysis, such as: the customer's number of credit inquiries in the past 3 / 6 / 12 months is > N times, the customer's number of loan overdue months in the past 3 / 6 / 12 / 24 months is > N, the customer's number of credit card / quasi-credit card overdue months in the past 3 / 6 / 12 / 24 months is > N months, whether the customer is a credit-cleared household.

[0073] It is understandable that the specific parameter thresholds of the above rules can be adjusted by business management personnel according to actual conditions.

[0074] For the rules derived from business experience and data analysis, on the one hand, we can summarize them from the anomalies found in daily business feedback and report monitoring, extract common problems and form rules; on the other hand, we can use machine learning algorithms such as decision trees to find out the features and corresponding thresholds that can provide more information for risk warnings.

[0075] S120. If it is in compliance, determining the customer group to which the declared information belongs based on the risk characteristics included in the declared information.

[0076] Among them, if the risk rules are met, the customer group to which the declared information belongs can be determined based on the risk characteristics included in the declared information. The distribution of applicant customers is composed of multiple customer groups with different risk characteristics. These sub-customer groups are separated in the risk assessment stage to facilitate more accurate judgments later.

[0077] In this solution, optionally, determining the customer group to which the declared information belongs based on the risk characteristics included in the declared information includes:

[0078] Obtain the risk characteristic dimensions included in the declared information;

[0079] If the risk characteristic dimension includes a target dimension, the customer group to which the declared information belongs is determined based on the risk characteristic value of the target dimension.

[0080] There can be many risk feature dimensions. If the dimension of division includes the target dimension, the customer groups can be divided according to the different values ​​of the target dimension. The target dimension can be one or more. For example, if the target dimension includes the house transaction price, the division can be based on the high or low house transaction price. If the target dimension includes the mortgage period of the loan, the division can be based on the length of the mortgage period. Through such a setting, the division result of the customer group to which the lender belongs can be obtained based on the declared information.

[0081] In this solution, optionally, the target dimensions include city level dimension, purchased house type dimension and transaction price dimension;

[0082] Determine the customer group to which the declared information belongs based on the risk characteristic value of the target dimension, including:

[0083] The customer group to which the declared information belongs is determined based on the risk characteristic values ​​of the target dimensions including the city level dimension, the purchased house type dimension and the transaction price dimension.

[0084] Among them, the city level dimension, the type of house purchased dimension and the transaction price dimension can be the most direct basis for evaluating the house purchasing behavior of the lender. Based on these target characteristics, the lender can be divided into customer groups more accurately.

[0085] In the above technical solution, optionally, the risk characteristic values ​​of the city level dimension include: first-tier cities, second-tier cities and third-tier cities;

[0086] The risk characteristic values ​​of the housing type dimension include: new housing and second-hand housing;

[0087] The risk characteristic values ​​of the transaction price dimension include: higher than the preset price and lower than the preset price.

[0088] Among them, first-tier cities, second-tier cities, and third-tier cities can be determined according to the national city classification standards. New houses and second-hand houses can be determined according to the information of house purchases. Higher than the preset price and lower than the preset price can be determined according to the comparison results with the preset price. Through such settings, a clear division method can be given for the feature values ​​of the target features, thereby improving the consistency of the customer group division results.

[0089] In the above technical solution, optionally, the preset price is determined according to the city level dimension and the house type dimension. For example, if the house currently purchased by the borrower is in Shanghai, the city level is level one, and the preset price can be relatively high, such as RMB 10 million. If it is in Harbin, the city level is level two, and the preset price can be relatively low, such as RMB 1.5 million. Thus, different preset prices can be determined according to different city levels, so that the preset price can correspond to the current city level.

[0090] In the above technical solution, optionally, if the risk characteristic value of the city level dimension is a third-tier city, then: determine the customer group to which the declared information belongs based on the risk characteristic value of the house purchase type dimension.

[0091] It is understandable that if it is a third-tier city, the target features can be determined only as the city level and house type, so that there is no need to divide the transaction price, thereby avoiding the large difference in consumption levels between third-tier cities, resulting in the customer segmentation results being unable to truly reflect the lender's loan risk.

[0092] Taking into account stability, differentiation, and interpretability, customers are segmented according to three dimensions: region, house transaction price, and whether it is a new house. According to the performance of customer risk characteristics, a risk control model is established for each customer group. The specific level division can be shown in the following table:

[0093]

[0094] It is understandable that different customer groups can be distinguished by different tags. In the subsequent processing, the model to be selected can be determined by simply obtaining the tag of the customer group.

[0095] S130: Perform risk assessment using a pre-approval risk control model associated with the customer group.

[0096] The relationship between the customer group and the pre-approval risk control model can be predetermined. After the customer group is determined, the corresponding pre-approval risk control model can be used to perform risk assessment. The result of the risk assessment can be two classification results of risk or no risk, or multiple risk levels.

[0097] The pre-approval risk control model uses the lightGBM model. GBDT (Gradient Boosting DecisionTree) is a classic model in machine learning. Its main idea is to use weak classifiers (decision trees) for iterative training to obtain the optimal model. This model has the advantages of good training effect and low overfitting. GBDT is not only widely used in the industry, but is also commonly used for multi-classification, click-through rate prediction, search ranking and other tasks. It is also a deadly weapon in various data mining competitions. According to statistics, more than half of the champion solutions in Kaggle competitions are based on GBDT. LightGBM (Light GradientBoosting Machine) is a framework for implementing the GBDT algorithm. It supports efficient parallel training and has the advantages of faster training speed, lower memory consumption, better accuracy, and support for distributed processing of massive data.

[0098] Common machine learning algorithms, such as neural networks, can be trained in mini-batch mode, and the size of the training data is not limited by memory. However, GBDT needs to traverse the entire training data multiple times in each iteration. If the entire training data is loaded into memory, the size of the training data will be limited; if it is not loaded into memory, repeatedly reading and writing the training data will consume a lot of time. In particular, when faced with massive industrial-level data, ordinary GBDT algorithms cannot meet its needs.

[0099] The main reason for proposing LightGBM is to solve the problems encountered by GBDT in massive data, so that GBDT can be used in industrial practice better and faster.

[0100] S140. If the risk assessment result is passed, the declared information is scored using a preset scoring card to obtain the result of online pre-approval.

[0101] If the risk assessment result is passed, a predetermined score card can be used to score the declared information. It can be understood that the score card is a model commonly used in the financial field to score risk levels.

[0102] In this solution, optionally, a preset scoring card is used to score the declared information to obtain the result of online pre-approval, including:

[0103] The declared information is scored using a preset scoring card, and if the scoring result is higher than a first threshold value, online approval recommendation information is generated.

[0104] Among them, the full score can be 500 points, and the first threshold value can be 400 points. It can be understood that the higher than here can also include the equal to situation, or the threshold value can be set to a decimal, such as 399.5, so that after obtaining the integer scoring result, all possibilities can be fully covered.

[0105] Here, if the score during the pre-approval process is above 400 points, the online approval recommendation information can be directly generated. The recommendation information can be sent to the account manager or the lender for the account manager to confirm and execute the corresponding process.

[0106] On the basis of the above technical solution, optionally, the method further includes:

[0107] If the scoring result is lower than the first threshold value and higher than the second threshold value, the declared information is determined to be low-risk information, and offline approval recommendation information is generated; wherein the second threshold value is lower than the first threshold value.

[0108] The second threshold value can be 200 points. If the score is lower than 400 points and higher than 200 points, it can be determined as low risk and the offline approval process is recommended. The advantage of this setting is that the means and severity adopted in the subsequent approval process can be determined, and then the approval resources can be deployed to achieve reasonable allocation of resources.

[0109] On the basis of the above technical solution, optionally, the method further includes:

[0110] If the scoring result is lower than the second threshold value, the declared information is determined to be high-risk information, and offline approval recommendation information is generated.

[0111] When the score is lower than 200 points, the declared information can be identified as high-risk and offline approval can be adopted, so that more approval resources can be allocated to it to ensure the security of the loan.

[0112] The technical solution provided in the embodiment of the present application obtains the lender's declaration information and executes the preset risk rules to determine whether the declaration information meets the rule standards; if it does, the customer group to which the declaration information belongs is determined based on the risk characteristics included in the declaration information; a pre-approval risk control model associated with the customer group is used to perform risk assessment; if the risk assessment result is passed, the declaration information is scored using a preset scoring card to obtain the result of online pre-approval. The technical solution provided in the present application can adopt different pre-approval methods for different customer groups to achieve the purpose of quickly and accurately pre-approving mortgage loans.

[0113] Figure 2 is a schematic diagram of another online pre-approval method for mortgage provided in an embodiment of the present application, such as Figure 2 As shown, the method includes the following steps:

[0114] The first step is to query the customer's internal and external data and execute the risk rule set. After the customer enters simple information in the mobile banking client and confirms that the customer is eligible to buy a house, the bank's internal information, credit data and other external information of the lender and co-lenders will be queried with the customer's authorization, and the risk rule set will be executed. Customers who do not meet the rule conditions will be notified of the rejection result or transferred to the offline supplementary materials to continue the application.

[0115] The second step is to divide the customers who pass the risk rules. Usually, our application customers are composed of multiple customer groups with different risk characteristics. These sub-customer groups are separated in the risk assessment stage to facilitate more accurate judgments later.

[0116] In the third step, different customer groups use different pre-approval risk control models for risk assessment. In the model development stage, training models for different customer groups separately can enable machine learning models to learn customer risk characteristics more specifically. In this step, the risk of customers is assessed through the model and the data obtained previously. Customers with low risks continue with the subsequent process, while other customers will be informed of the rejection result or transfer to offline supplementary materials to continue the application.

[0117] The fourth step is to carry out the follow-up process and run the existing scorecard. Customers who have passed the pre-approval risk control model will carry out the follow-up process. Customers who have passed the aforementioned risk control model will carry out the follow-up application process and continue to score customers with the existing scorecard. The new risk control model is trained and verified based on three dimensions: city level, whether it is a new house, and transaction price. There are obvious differences in the qualifications, repayment performance, and behavioral performance of customers in different customer groups. Scoring customers by customer group makes the scoring model more targeted and more accurate in obtaining the customer's comprehensive score than the existing scorecard.

[0118] Compared with the original mortgage model, this solution uses the same set of scoring cards for all applicants. In fact, mortgage customers are composed of customers at different levels, and customers at each level have different risk performance and characteristics. The present invention combines business explainability and customer behavior to find out the three dimensions of city level, whether it is a new house, and house transaction price to stratify mortgage customers. Compared with the original model that treats all mortgage customers as a whole, stratifying customers according to this method is more conducive to targeted modeling and strategy formulation.

[0119] Moreover, based on the original mortgage scoring card model, a pre-approval risk control model is deployed in the early stage of the application process. Compared with the traditional one-model approach, it can quickly complete the risk pre-assessment of customers, and provide early warnings and follow-up process guidance. It shortens the loan application life cycle, effectively reduces the time cost of customers waiting, and improves customer experience. The specific process includes: data collection, risk assessment, and risk classification by customer group.
