The invention aims to form a set of factorization rule evaluation method according to the characteristics of different factors of the severe risk products in different dimensions, comprehensively evaluate the severe risk products from multiple angles and score each product. Specifically, the method analyzes the main characteristics and the dimensions of the severe danger products, determines a key scoring factor under each dimension, quantifies the scoring factors, gives the weight of each scoring factor under each dimension and the weight of each dimension in a product scoring model, calculates the score of the dimension comprehensively and finally obtains the score of the product.
Specifically, fig. 1 schematically shows a flow chart of a method for scoring a severe risk product based on factorization rules according to a preferred embodiment of the present invention.
Dividing product dimensions: according to the characteristics of the products with severe risks, the scoring factors are divided into three dimensions,
specifically, the three dimensions are a guarantee range dimension 1, an underwriting condition dimension 2, and a rate dimension 3.
Thinning step: refining the scoring factor of each dimension to obtain a factor 1 and a factor 2 … factor n;
for example, for a guaranteed range dimension of 1: the severe risk products in the market are comprehensively analyzed, the grading factors of the severe risk guarantee range can be refined according to the sub-dimensions of severe diseases, specific diseases, personal problems, intermediate symptoms, mild symptoms and the like, the 32 grading factors are obtained through sorting, and the relevant grading factors under each sub-dimension are the factors 1-32 shown in the following table.

A factor quantization step: quantifying the scoring factor;
the value of a factor generally has two forms, one non-numeric and one numeric.
(1) For factors in non-numerical form, since the result is expressed in words, such as the factor "whether the disease is serious or not, the content is" yes "or" no ", and the factor content needs to be quantified when calculating the score.
(2) For the factors in the form of numerical values, since the dimensions of each factor are not necessarily identical, in order to reduce the influence of different dimensions on the result, the factors need to be quantized uniformly. The rules for quantization are also different in combination with the characteristics of each factor.
Fn are used, for example, to represent factor quantization scores, F1, F2.i1, 2.., 37, representing a factor 1-factor 37 quantization score.
