Problems solved by technology
Provides a real-time monitoring of the operation of the current credit scoring model, which solves the problem of inaccurate credit scoring caused by the inability to update the credit scoring model in the existing technology, and can automatically identify the concentration of model information attributes such as current public opinion, laws, and regulations. The reliability of attributes reduces the external risks faced in the current policy fluctuation period, further improves the adaptability of the credit scoring model, reasonably sets the update cycle of the credit scoring model, and improves the performance of the credit scoring system
Its shortcoming is that it does not consider the change of model indicators in the time dimension, so it lacks the expression of the change of credit index in the time dimension
However, comments on e-commerce platforms do not necessarily play a decisive role. What is more important is the inspection report of the product by the offline National Quality Supervision Bureau and a third-party quality inspection company entrusted by the government; the evaluation of different products is too general, such as purified water It is obviously difficult to be the same as the evaluation criteria of the trolley case. The importance of the same index is also very different. There are great differences between different categories of products. A single evaluation standard cannot ensure the effectiveness of the evaluation and provide consumers with accurate reference.

The invention relates to electronic commerce, aiming at providing a method and a system for analyzing quality credit indexes of e-commerce products. A method for analyzing the quality credit index ofe-commerce products comprises steps: defining an index for constructing the e-commerce product quality credit index, obtaining an initial e-commerce product quality credit index of each commodity according to a hierarchy, calculating an original growth rate of an instrumental variable corresponding to the index of each commodity in a time dimension, and modifying the original growth rate to obtaina modified growth rate algorithm; the algorithm of updating the quality credit index of historical e-commerce products by using the revised growth rate being provided; finally, the quality credit index and voting rights of each commodity being collected to calculate the quality credit index of e-commerce products in the overall industry. The invention is an innovative calculation method for analyzing the quality credit index of e-commerce products, which can carry out in-depth analysis on the e-commerce products, can truthfully depict the track of the development fluctuation of the e-commerceproducts, and can effectively monitor the development trend of the e-commerce products industry.
Description
technical field [0001] The invention relates to the field of e-commerce, in particular to an analysis method and system for an e-commerce product quality credit index. Background technique [0002] The use of e-commerce is becoming more and more widespread. Many e-commerce platforms such as Tmall and JD.com have greatly facilitated people's lives. Users are increasingly concerned about product quality. However, only relying on online user reviews on e-commerce platforms to judge the quality of products Bad still has certain limitations.
