Rule extraction method based on offline data, storage medium and electronic equipment

The invention relates to the field of data processing, in particular to a rule extraction method based on offline data, a storage medium and electronic equipment. Comprising the steps of obtaining an initial data set of a plurality of description fields of a target event; and performing character type conversion processing on each piece of field data to generate corresponding character data. And generating a character confidence coefficient set corresponding to each initial data set according to the character data. And according to the confidence in each character confidence set, generating a data judgment rule of the corresponding description field. According to the method and the device, the character type conversion processing is performed on the description data, so that the character composition form corresponding to each description data can be obtained. And then according to the confidence coefficient, determining a data form which is most likely to appear in each description field. And the data form i
