Food safety risk analysis and prediction method based on big data

The invention provides an enterprise-level food safety risk analysis and prediction method based on big data. Belongs to the food safety field. Firstly, a food safety risk factor keyword library of a specific food industry is determined, then information about food safety is extracted from different data sources through a deep learning model, such as a BERT model, and then an evaluation index system for evaluating specific food safety risk factors is constructed. The system comprises an evaluation index framework of risk factors, and a credible data source type and a data quantification scheme table of specific indexes. And finally, on the basis of the constructed food safety risk index system, performing comparison of transverse food safety risk current situations between different enterprises of the same type according to the same standard. According to the method, food safety big data and deep learning technologies are utilized, the accuracy of food safety risk prediction is improved, and a more quantitati
