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 present invention relates to e-commerce, and aims to provide a method and system for evaluating the quality of e-commerce products. This kind of e-commerce product quality evaluation method first defines the indicators used to construct the e-commerce product quality credit index, obtains the initial e-commerce product quality credit index of each commodity by level, and then calculates each commodity with time as the dimension The original growth rate of the instrumental variable of the corresponding indicator, and the algorithm for modifying the original growth rate to obtain the revised growth rate; the algorithm for updating the historical e-commerce product quality credit index using the revised growth rate; finally, collect each product The quality credit index and voting rights are used to calculate the overall industry's e-commerce product quality credit index. The invention is an innovative calculation method for evaluating the quality of e-commerce products, which can conduct in-depth analysis on e-commerce products, can faithfully describe the developmental trajectory of e-commerce products, and effectively monitor the development trend of the e-commerce product industry.
Description
technical field [0001] The invention relates to the field of e-commerce, in particular to a method and system for evaluating the quality of e-commerce products. 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.

Information asymmetry, incompleteness, and opacity make it impossible for users to make scientific and effective decisions, and thus unable to choose high-quality products on the e-commerce platform according to their own wishes. In the long run, it will not only cause unpleasant user experience, but eve...
