摘要:Commodity evaluation on e-commerce platforms affects the sale of goods and the behavior of buyers. Although the observation point of static event theory is stable, it emphasizes one-sided data too much. It ignores the interconnections in the development of events and makes it difficult to effectively analyze the validity of commodity evaluation behaviors. Under the concept of dynamic transaction events based on dynamic development, the validity of commodity evaluation is calculated from time, space and intensity factors. This can consider the influence of individual evaluator and overall evaluator to evaluate the validity of commodity evaluation systematically and objectively.
