Referring to FIG. 3 , the credit evaluation basic data 300 may be transmitted to the credit evaluation basic data learning unit 360 as the first preprocessing credit evaluation basic data 320 through the first preprocessing 310 . In addition, the credit evaluation basic data 300 may be transmitted to the credit evaluation unit 370 as the second preprocessing credit evaluation basic data 355 through the second preprocessing 350 .

The first pre-processing 310 may be pre-processing for learning in an artificial intelligence engine.

The first pre-processing 310 may be performed in consideration of characteristics of the sales management platform that generated the credit evaluation basic data 300 . In the present invention, since the financial service is provided considering seller characteristics and supply chain characteristics, the first pre-processing 310 may be performed to learn the artificial intelligence engine considering the seller characteristics and supply chain characteristics.

Among the first preprocessing 310 , preprocessing considering supply chain characteristics may be performed in consideration of a supply chain step corresponding to the credit evaluation basic data 300 . Among the first preprocessing 310 , preprocessing considering supply chain characteristics may be expressed as a first preprocessing (supply chain) 313 .

For example, when a supply chain is divided into a production (or purchase) stage, a distribution stage, and a sales stage, the credit evaluation basic data 300 is primarily credit evaluation basic data (production phase) based on the stage at which the data was acquired. ), credit evaluation basic data (distribution phase), and credit evaluation basic data (sale phase), and may be generated as first pre-processed credit evaluation basic data 320 .

When credit rating base data for the same product is duplicated in a plurality of sales management platforms, duplicate data processing may be performed. For example, when a seller purchases a specific product for sale, the product may be registered on the OMS and the product may be placed on the WMS. That is, an act of purchasing a specific product by a seller is performed only once, but data on product registration and product placement resulting from such a purchase action are generated for each sales management platform, which may result in duplication of basic credit evaluation data.

The first pre-processing (supply chain) 450 determines the redundancy of the transmitted credit rating basic data in consideration of the data generation time of the credit rating basic data, the information included in the credit rating basic data, and the later transmitted credit evaluation basic data information. Thus, first pre-processing credit evaluation basic data 490 may be generated. When duplication of credit evaluation basic data occurs, only data of one sales management platform is used through the first preprocessing (supply chain) 450, or duplicated credit evaluation basic data is filtered out and duplicate credit Only other credit evaluation basic data including information included in the evaluation basic data may be used.

Also, the first pre-processing (supply chain) 450 may be pre-processing of credit evaluation basic data considering time.

The seller's credit rating and the data underlying the seller's credit rating may change over time. Therefore, setting a time scale for credit evaluation basic data for learning may greatly affect the performance of the artificial intelligence engine. Accordingly, in the present invention, after setting a time scale for the obtained basic credit evaluation data, the first preprocessed basic credit data 490 may be generated by pre-processing the basic credit evaluation data considering the time scale. A time scale for preprocessing may be set for each credit evaluation basic data.

Among data augmentation methods, a method of augmenting data by analyzing credit evaluation base data on a time scale may be expressed as a time scale data augmentation 610 .

For example, when the credit evaluation basic data 600 is a return rate, data on the number of sellers with a monthly return rate of 5% or more for 36 months may be augmented and generated based on the monthly return rate of 5% or more. As another example, based on the average monthly return rate, data on the number of sellers with an average return rate for 36 months may be augmented and generated.

(b) of FIG. 6 is a method of augmenting data by statistically analyzing the credit evaluation base data 650 among data augmentation methods.

A first pre-processing (seller) may be selectively performed to learn the plurality of artificial intelligence engines included in the credit evaluation basic data learning unit.

For example, the sub-data augmentation 810 may be used for training of an artificial intelligence engine to generate a specialized result through specific analysis of characteristic credit evaluation data among artificial intelligence engines. For example, sub-data augmentation for the return rate may be performed for learning of an artificial intelligence engine that generates credit evaluation data with more weight on the return rate.

Time scale data augmentation 820 can be used to train an artificial intelligence engine to predict changes in credit rating data over time.

Statistical data augmentation 830 may be used for training of an artificial intelligence engine for predicting credit evaluation data according to separately preset specific criteria.

Accordingly, optimal artificial intelligence engine learning may be performed through scaling 1210 for each of a plurality of credit evaluation base data included in the secondary candidate scorecard 1240 .

The creation time point adjustment 1220 (or scoring time point adjustment) may perform learning of the artificial intelligence engine in consideration of the generation time point (or scoring time point) of the credit evaluation base data. A plurality of credit evaluation basic data included in the scorecard may be grouped and input to the artificial intelligence engine. Accordingly, it is possible to determine which learning data is generated by setting a generation time point of the credit evaluation basic data. Therefore, more accurate learning of the artificial intelligence engine can be performed through the adjustment of the generation time point 1220 of the credit evaluation basic data.

In addition, the creation time point adjustment 1220 may reduce a score error generated according to the generation time point by setting a plurality of creation time points. In the basic credit evaluation data, the observation period 1250, the scoring time 1260, and the operation period 1270 are separately classified, and the observation period 1250 and the operation period 1270 are set differently to set a plurality of scoring times 1260. can be set By setting a plurality of scoring time points 1260, it is possible to reduce a score error according to the time of creation, which may occur according to a seller's product, such as a seasonal change, and to reflect the score change according to time.
