And if the matching degree is lower than a preset matching degree threshold (for example, 85%), further taking the initial event description information as the input of the backtracking model to obtain a case matching result. And finally, taking the category and the name of the hazard factor as the input of an auxiliary decision-making model, and outputting recommended experts for remote visual diagnosis and decision-making. If the user inputs symptoms: "abdominal pain, colic, stomach discomfort", age: and (4) eating food for 18-22 years: the method comprises the following steps that key characteristics of uncooked beef and the like can be accurately predicted through a hazard factor prediction model, the types of hazard factors and similarity scores of hazard factors corresponding to categories can be accurately predicted, ranking is taken as a recommendation basis according to scores, and here, hazard factors of the first three ranking are extracted as recommendations, such as: salmonella, escherichia coli, clostridium perfringens.
