Background
Food safety emergencies are always highly valued by current health departments, and most of emergency treatment aiming at the food safety emergencies are currently processed in the market in a mode of seeking diagnosis and treatment in hospitals after finding problems or asking and answering doctors through a network on line. These approaches do not allow for timely management of emergency procedures, which may result in even worse results and even life safety hazards for the emergency patient due to the failure to obtain current emergency procedures and measures at the first time. At present, a recommendation system for creating an emergency method for food emergencies has the following problems which are not solved yet: 1. the lack of the database means that the data set for sorting food safety emergencies at the present stage is not complete, wherein the data set comprises the root cause of the occurrence of the food safety emergencies, namely hazard factors, the categories of the hazard factors and the emergencies caused by the specific hazard factors, which are not related in detail; for example, biohazard factors include bacteria, fungi, viruses and natural toxins, and various subtypes exist among them, and the emergent events caused by them are also obviously different to some extent. 2. The development of a data clustering algorithm aims at the treatment mode of food safety emergencies, mostly carries out clustering through symptoms of patients, the selected data characteristics are relatively limited, a common symptom-disease supervision model of a Meiao clinic exists, the probability of a certain person suffering from the disease is diagnosed according to the symptoms and other characteristics, and a prescription which responds is recommended through the symptoms, and the like. In practical situations, although machine learning models and natural language models have been widely used, in specific projects, the selection of features in the data mining process is crucial, and the accuracy and generalization capability of prediction or recommendation are directly influenced. This is one of the main reasons why an accurate model for emergency method recommendation for food safety emergencies has not been developed yet. 3. The recommendation of the expert remote visual emergency method is an unsolvable problem for how to select a proper expert to carry out remote visual diagnosis and decision under the condition that the two problems are not solved. The accurate expert recommendation result depends on the clustering result of the hazard factor category and the name of the specific hazard factor. Therefore, specific experts in the field are recommended, and remote visual emergency method recommendation is given to the serious situation person at the first time.
Therefore, how to obtain an emergency method in a simple manner for a user in the first time when the user is confronted with a food safety emergency is an urgent problem to be solved.

Fig. 3 shows a data flow chart of an emergency treatment recommendation method for food safety emergencies according to an embodiment of the present invention, specifically, a recommendation score of an emergency method is obtained by using description information of a user (i.e., a patient) for an emergency, as an input of a hazard factor prediction model, the model outputting a category of toxic hazard factors, and a hazard factor name with a matching degree higher than a preset matching degree threshold (e.g., 85%), and then entering a standard evaluation model. 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. And further querying a hazard factor database to obtain a corresponding emergency method, and evaluating the emergency method according to the standard scheme scoring model. Finally, standard emergency method recommendation is obtained. Including specific experts obtained by hazard factor query correlation.
In some embodiments, step 100 of the emergency treatment recommendation method for food safety emergencies of the present invention comprises:
acquiring a description text of an emergency event input by a user;
in this step, for the voice input by the user, the voice needs to be converted into a described text.
And analyzing the description text of the emergency and extracting key features to obtain the description information of the user emergency.
In the step, the description text of the emergency can be analyzed by adopting the existing semantic analysis method, and then the key features are extracted according to the analysis result, so that the description information of the user emergency can be obtained. Symptoms such as those caused by clostridium perfringens: acute gastroenteritis type: more than 90% of patients have acute gastroenteritis such as abdominal distention, abdominal pain, diarrhea, etc. Abdominal pain can be manifested as severe colic, diarrhea is usually loose or watery stool, and sometimes mucous stool or bloody stool.
