[0027] Figure 2 is a specific embodiment flowchart of the claim case reduction method provided by an embodiment of the present application, as shown in Figure 2 , which can specifically include the following steps:

[0028] S10, obtaining claim data of a to-be-audited claim case, the claim data comprising a claim amount, product information and customer information.

[0029] In this step, the claim data of the to-be-audited claim case is obtained. The claim data comprises a claim amount, product information and customer information. The claim amount refers to the specific amount of money required by the applicant for compensation or the specific amount of money initially determined by the claim personnel. The product information includes the type of insurance product, the scope of protection, the term of protection, etc. The customer information includes the customer's age, occupation, previous claim record, financial status and other relevant information.

[0030] S20, inputting the claim data into a pre-trained loss scale prediction model to obtain the loss scale of the to-be-audited claim case.

[0031] In this step, the claim data is inputted into a pre-trained loss scale prediction model to obtain the loss scale of the to-be-audited claim case. The loss scale refers to the amount of claim that can be reduced after the audit, which is an important indicator for measuring the risk of claim.

[0032] S30, if the loss scale is greater than a preset threshold, marking the to-be-audited claim case as an audit failure case and sending a prompt message to the claim personnel, the prompt message comprising the loss scale.

[0033] In this step, it is determined whether the loss scale is greater than a preset threshold. The preset threshold can be determined according to the risk management strategy of the insurance company and historical data analysis, and is usually set to a value that can effectively screen out high-risk cases. If the loss scale is greater than the preset threshold, the to-be-audited claim case is marked as an audit failure case, and a prompt message is sent to the claim personnel, the prompt message comprising the loss scale.

[0034] In one specific embodiment, the to-be-audited claim case A is a car insurance claim case, and the claim amount is 86500 yuan. The product information is high-end comprehensive insurance, the coverage is 200000 yuan, the scope of protection includes vehicle damage + third party, the delay in reporting the case is 48 hours, and the vehicle type is an imported luxury SUV. The customer information is: male, 32 years old; the number of historical claims in the past two years is 5 times; the financial status is excellent. The above claim data is inputted into a pre-trained loss scale prediction model to obtain a loss scale of 30000 yuan. If the preset threshold is 20000 yuan, the loss scale of the to-be-audited claim case A is greater than the preset threshold, and a prompt message of "there is a loss of 30000 yuan in this case, please verify the customer's materials and fees, confirm the loss amount, and resubmit the audit" is sent to the claim personnel of the to-be-audited claim case A.

[0035] In another specific embodiment, the to-be-audited claim case B is a health insurance claim case, and the claim amount is 32000 yuan. The product information is: high-end medical insurance; the guarantee range is full coverage of special ward and imported drugs; the report delay is 7 days. The customer information is: female, 58 years old; 4 times of the same type of hospitalization claim within 3 years. The above claim data is input into the pre-trained loss scale prediction model, and the loss scale is 25000 yuan. If the preset threshold is 15000 yuan, the loss scale of the to-be-audited claim case B is greater than the preset threshold, and the prompt information "there is a loss space of 25000 yuan in this case. Please verify the customer materials and fees, confirm the loss amount, and resubmit the audit" is sent to the claim personnel of the to-be-audited claim case B.

[0036] The claim case loss method of the embodiment inputs the claim data including the claim amount, product information and customer information into the pre-trained loss scale prediction model to obtain the loss scale of the to-be-audited claim case. If the loss scale is greater than the preset threshold, the to-be-audited claim case is marked as an audit failure case, and prompt information including the loss scale is sent to the claim personnel. There is no need to judge the loss scale by artificial means, which saves labor costs and improves the efficiency of judging the loss scale. At the same time, non-professional claim personnel can also verify the claim case according to the loss scale in the reference prompt information, fully utilize all human resources, save the claim cost of the insurance company, and improve the claim efficiency.

[0037] Figure 3 is Figure 2 The flowchart of one specific embodiment in step S20 is shown in FIG. 2. As shown in FIG. 2, in some embodiments, the training steps of the violation detection model are as follows: Figure 3

[0038] S31, obtaining historical claim data of historical claim cases, the historical claim data including claim amount, product information, customer information and loss scale.

[0039] In this step, the historical claim data of the historical claim cases is obtained, and the historical claim data includes the claim amount, the product information, the customer information and the loss scale. The historical data is usually derived from the records of the claim cases handled by the insurance company in the past, which contains complete claim process information and final results.

[0040] S32, processing the historical claim data to obtain a target sample set, and dividing the target sample set into a target training set, a target validation set and a target test set according to a preset proportion.

[0041] In this step, the target sample set is divided into a target training set, a target validation set and a target test set according to a preset proportion. Usually, a 7:2:1 or 8:1:1 proportion is used for division to ensure the scientificity of model training and evaluation.​

[0042] S33, training the target sample set by using the XGboost algorithm to obtain a trained loss scale prediction model.

[0043] In this step, the target sample set is trained by using the XGboost algorithm to obtain a trained loss scale prediction model. XGBoost (eXtreme Gradient Boosting) is a high-efficiency machine learning algorithm based on gradient boosting decision tree, which can output key influencing variables through feature importance analysis to assist business decision optimization. Through actual test, the XGboost algorithm performs outstandingly in loss scale prediction in the loss scale prediction model of the embodiment.

[0044] In the above embodiment, the loss scale prediction model is trained by taking the historical claim data as the training set, which realizes the knowledge precipitation of the artificial judgment loss rule, converts the loss labor tilt problem into an automatic technical solution, saves the labor cost, promotes the achievement of the individual value contribution index of the claim staff, and saves the claim cost of the insurance company.

[0045] In one specific embodiment, the historical claim data is obtained by setting a time window to move and filter regularly, such as setting the historical claim data set filtering condition as the claim data of the historical claim cases in the last three years. The purpose is to enable the latest loss success cases to participate in training as features in time, and when the claim settlement is completed, new claims also enter the database for model training, so as to ensure the accuracy and effectiveness of the model with version iteration prediction model, and facilitate the next claim loss judgment.

[0046] Figure 4 is Figure 3 Another specific embodiment flowchart of step S32 is shown in FIG. 3B, in which, in some embodiments, the historical claim data is processed in step S32 to obtain a target sample set, specifically including: Figure 4

[0047] S321, performing outlier processing on the historical claim data to obtain a first sample set, performing missing value processing on the first sample set to obtain a second sample set, performing feature selection and feature importance sorting on the second sample set to obtain the target sample set.

[0048] ​In this step, the outlier processing mainly adopts the box plot method and Z-score method to identify and process abnormal data points, including eliminating abnormal values such as claim amount exceeding the coverage. The missing value processing adopts methods such as mean / median filling, nearest neighbor filling or prediction model filling according to the characteristics of the data. In the feature selection process, the most valuable feature variables for damage scale prediction are selected through correlation analysis, variance analysis and other methods, such as claim frequency > claim amount > financial stability level.

[0049] Figure 5 is Figure 3 Another specific embodiment of step S33 is shown in the flowchart of Fig. 6. As shown in Fig. 6, in step S33, the XGboost algorithm is used to train the target sample set to obtain a trained damage scale prediction model, which includes: Figure 5

[0050] S331, using the XGboost algorithm to train the target training set to obtain a preliminarily trained damage scale prediction model;

[0051] S332, verifying and adjusting the preliminarily trained damage scale prediction model according to the target verification set to obtain a verification-completed damage scale prediction model;

[0052] S333, testing and evaluating the verification-completed damage scale prediction model according to the target test set to obtain a test evaluation result, and obtaining a trained damage scale prediction model when it is detected that the test evaluation result meets a preset requirement.

[0053] In this embodiment, the XGboost algorithm is used to train the target sample set to obtain a trained damage scale prediction model. The specific training process includes three stages: first, the XGboost algorithm is used to train the target training set to obtain a preliminarily trained damage scale prediction model; second, the preliminarily trained damage scale prediction model is verified and adjusted according to the target verification set to obtain a verification-completed damage scale prediction model, which mainly optimizes the model performance by adjusting the learning rate, the depth of the tree, the regularization parameter and other hyperparameters; finally, the verification-completed damage scale prediction model is tested and evaluated according to the target test set to obtain a test evaluation result, and a trained damage scale prediction model is obtained when it is detected that the test evaluation result meets a preset requirement. The preset requirement usually includes that the model accuracy, precision, recall, F1 score and other indicators reach a specific threshold.

[0054] In some embodiments, the prompt information in step S30 further includes:

[0055] ​Customer tags and prompt text and communication scripts generated based on the customer tags; the customer tags are generated based on the customer information using the K-means clustering algorithm, and the customer tags include high-risk management customers, low-risk management customers, financially stable customers, and financially stressed customers.

[0056] In this embodiment, customer tags are generated based on customer information using a K-means clustering algorithm. These tags represent the customer's personalized characteristics, including but not limited to high-risk management customers, low-risk management customers, financially stable customers, and financially strained customers. This allows claims personnel to select appropriate communication scripts based on the customer's individual characteristics when communicating with them. For different customer tags, corresponding prompts and communication scripts are automatically generated based on historical claims data, helping claims personnel communicate more effectively with customers, improving claims processing efficiency and customer satisfaction. In other embodiments, customer tags can also be used as samples for training and prediction of loss reduction prediction models.

[0057] In one specific implementation, when dealing with high-risk management clients, the following prompt text and communication script are generated:
