[0032] Example 1

[0033] In one embodiment of the present disclosure, an unemployment insurance fund supervision system based on big data and similar population expansion is provided, including:

[0034] The data collection module is configured to obtain unemployment insurance fund related data and construct a data set;

[0035] The data governance module is configured to pre-process the acquired unemployment insurance fund related data and use statistical methods to obtain data distribution and data correlation;

[0036] A supervision model building module is configured to build an unemployment insurance fund supervision model based on the preprocessed data through a linear regression algorithm, wherein the unemployment insurance fund supervision model identifies a target population for abnormal reporting based on the preprocessed relevant data;

[0037] The reverse supervision model construction module is configured to build a reverse supervision model for the unemployment insurance fund based on the target population for abnormal reporting output by the unemployment insurance fund supervision model. It uses a similar population expansion algorithm to analyze various characteristics of the target population for abnormal reporting and perform similarity calculations. It calculates the distances between various characteristic vectors to identify users similar to the target population for abnormal reporting, and realizes the association mining between abnormal reporting persons, enterprises, and batch abnormal reporting persons, so as to conduct subsequent supervision and review.

[0038] As an embodiment, in the data collection module, data related to the unemployment insurance fund is obtained and a data set is constructed, including: collecting data related to the unemployment insurance fund through multiple channels, including payment records, application information, approval results, labor contracts, contract signing records, etc., as well as data from external departments and institutions, and integrating these data together to form a complete data set.

[0039] In the data governance module, the obtained unemployment insurance fund-related data is preprocessed, including: data cleaning of the obtained data, identification of obviously erroneous data in the data, and screening out missing values, outliers, and inconsistent formats. Find and delete duplicate records, and only retain unique entries to avoid bias in the analysis process. Conduct in-depth exploratory analysis of the data, including data lineage tracking to understand the origin and flow of data, and use statistical methods to deeply analyze the characteristics of the data, take the mean, median and mode of the unemployment benefit collection data, that is, the average unemployment benefit collection value, median collection value, etc., and use standard deviation and variance to calculate the degree of deviation of the data. Including its distribution form and the correlation between variables, analyze the data distribution and data correlation. Data correlation refers to the existence of a certain statistical relationship between data. The change of one data can predict or explain the change of another data.

[0040] In the insurance fund supervision model construction module, first of all, the business data of abnormal cases of unemployment insurance benefits were analyzed, and a total of six types of abnormal unemployment insurance fund claims were identified, namely: 01-Employed 02-Enjoyed retirement benefits 03-False affiliation 04-False labor contract 05-Deceased 06-Others.

[0041] Then, an unemployment insurance fund supervision model is constructed with the linear regression algorithm as the core algorithm. The data required for model training include two categories. One category is internal business data, including insurance data, which is used to identify whether the insurance has been participated in; labor contract data is used to identify the authenticity of contract data; benefit data is used to identify whether the pension benefits have been enjoyed; employment data is used to identify whether the re-employment has been made; the other category is data shared by external departments, including death data, which is used to identify whether the person has died; and prison data, which is used to identify whether the person is serving a sentence during the period of collection.

[0042] The model is trained based on the accumulated data, and the best fitting line is found by minimizing the sum of squared errors. The model parameters obtained through regression analysis are used to establish a prediction model and predict future data points. Cross-validation technology is used to optimize model parameters to avoid overfitting.

[0043] Furthermore, the construction of the unemployment insurance fund supervision model includes:

[0044] Based on the aggregated and pre-processed high-quality business sedimentation data, with the linear regression algorithm as the core algorithm, the unemployment insurance fund supervision model is constructed through the construction methods such as problem definition, data collection, model selection, feature engineering, model training and evaluation. The essence of this model is to build a linear relationship between the abnormal type of unemployment insurance and various business data. The aggregated data includes internal data of human resources and social security, insurance data, labor contract data, benefit data, employment data, etc., and external department data includes prison data, death data, etc. The target population of abnormal declaration is taken as the target variable, and various characteristic data around the declarant are taken as characteristic variables. The unemployment insurance fund supervision model is based on the assumption of a linear relationship between the target variable (abnormal declarant) and the characteristic variable (various characteristic data around the declarant), and the characteristic variables are linearly combined to predict the value of the target variable.

[0045] The trained model was evaluated using the test data set to check the prediction accuracy and generalization ability of the model. Mean square error (MSE), root mean square error (RMSE), R^2 score and other methods were used to evaluate the model. Cross-validation and grid search were used to find the optimal combination of model parameters.

[0046] Based on the data calculated by the unemployment insurance fund supervision model, the personnel information and abnormal types that may exist are given, and the corresponding supporting explanations are given and pushed to the business personnel for confirmation and review.

[0047] In the reverse supervision model construction module, based on the target population of abnormal reporting output by the unemployment insurance fund supervision model, a reverse supervision model of the unemployment insurance fund is constructed through a similar population expansion algorithm. The various characteristics of the target population of abnormal reporting are analyzed and similarity is calculated. The distance between various feature vectors is calculated to identify users similar to the target population of abnormal reporting, realize the association mining of abnormal reporting person-enterprise-batch abnormal reporting person, and conduct subsequent supervision and review.

[0048] Based on the data calculated by the reverse supervision model of the unemployment insurance fund, the personnel information and abnormal types that may exist are given, and the corresponding supporting explanations are given and pushed to the business personnel for confirmation and review.

[0049] Furthermore, the reverse supervision model of unemployment insurance funds includes:

[0050] Using the two types of abnormal applicants, 03-false affiliation and 04-false labor contract, output by the unemployment insurance fund supervision model, the unemployment insurance fund supervision model is constructed based on the similar population expansion algorithm lookalike. The construction process of the model includes data collection and preprocessing, seed user definition, user portrait construction, selection of existing similarity calculation methods, model training and expansion population generation. The core of this model is to find similar people from massive data based on the characteristics of seed users (known abnormal applicants). Analyze the various characteristics of abnormal applicants, identify people who are highly similar to the given abnormal applicants from similar companies, and realize the association mining of abnormal applicants-enterprises-batch abnormal applicants, so as to achieve precise supervision.

[0051] Convert the input data into vectors, calculate the distance between vectors to find users similar to the seed users, and compare the vectors based on the seed users' characteristics such as work unit, age, industry, etc. to find similar users. Use the test data set to evaluate the constructed model and check the accuracy and stability of the model. Tune the model based on the evaluation results, including adjusting algorithm parameters and optimizing feature selection.

[0071] The unemployment insurance fund supervision result output module S106 provides two ways to use the model supervision capability. One is to perform batch supervision on completed businesses based on business sedimentation data after the fact. The other is to output the model capability to the business system and call the model capability API in real time during the business handling process to achieve process supervision. The two methods can be used in parallel.

[0072] The unemployment insurance fund reverse supervision module S107 is called for specific situations. For abnormal results such as 03-false affiliation and 04-false labor contract when calling the unemployment insurance fund supervision model, the unemployment insurance fund reverse supervision model is called again to further deepen the supervision, use the abnormal declarant as the seed, conduct reverse supervision, and find similar groups.
