Research and Analysis on Public Opinion Monitoring of Product Quality and Safety Accidents in 2021 through Crawler Retrieval Technology and Manual Data Retrieval

Abstract

Product quality and safety are related to the personal and property safety of the people. In recent years, the “Xi'an Aokai cable incident” and the “Fujian Zhangzhou big head doll incident” and other related product quality and safety incidents have not only caused personal harm and huge economic losses, but also have a certain negative impact on the law enforcement image of government departments. Therefore, it is particularly important to monitor the public opinion of product quality and safety accidents and explore the risk early warning mechanism. From the perspective of public opinion on product quality, this study searches, analyzes and summarizes the product quality information of 31 provinces in the country through crawler search technology and artificial data search, points out the existing problems, and puts forward corresponding countermeasures and suggestions. The survey results show that the public opinion information on product quality and safety in 2021 is mostly displayed in the second quarter, the eastern region and the categories of food, drugs and daily necessities. Quality defects are the main reason for product quality and safety incidents. Therefore, we should strictly control the production quality, strengthen market supervision, promote industry standardization and standardization, and promote market participants to implement their sense of responsibility, Provide reliable product quality assurance for economic and social development and people's life.
