Example Embodiment
[0024] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below with reference to specific embodiments and drawings.
[0025] The invention aims to form a set of factorized rule evaluation method based on the characteristics of different factors of critical illness insurance products in different dimensions, comprehensively evaluate critical illness insurance products from multiple angles, and score each product. Specifically, the present invention analyzes the main characteristics and dimensions of critical illness insurance products, determines key scoring factors in each dimension, quantifies the scoring factors, and assigns the weight of each scoring factor in each dimension, and the relationship between each dimension The weight in the product scoring model, comprehensively calculate the dimension score and finally obtain the product score.
[0026] Specifically, figure 1 Schematically shows a flow chart of a critical illness insurance product scoring method based on factorized rules according to a preferred embodiment of the present invention.
[0027] Steps to divide product dimensions: According to the characteristics of critical illness insurance products, divide the scoring factor into three dimensions,
[0028] Specifically, the three dimensions are coverage dimension 1, underwriting condition dimension 2, and premium rate dimension 3.
[0029] Refinement step: Refine the scoring factor of each dimension to obtain factor 1, factor 2... factor n;
[0030] For example, for the coverage dimension 1: Comprehensive analysis of critical illness insurance products on the market, the critical illness insurance coverage can be refined according to sub-dimensions such as critical illness, specific disease, death, moderate illness, and mild illness. After sorting, 32 scoring factors are obtained, and the related scoring factors in each sub-dimension are as shown in the following table: Factor 1-factor 32
[0031] Factor number Factor name Factor 1 Number of serious illnesses Factor 2 Whether the serious illness is paid multiple times Factor 3 Whether the serious illness is grouped Factor 4 Number of critical illness groups Factor 5 Number of benefits Factor 6 Interval between multiple claims for critical illness Factor 7 Whether malignant tumors are grouped separately Factor 8 Critical Illness Waiver
[0032] Factor number Factor name Factor 9 Whether it contains specific diseases Factor 10 Number of diseases in special cities Factor 11 Whether it contains children's specific diseases Factor 12 Children. Number of specific diseases Factor 13 Liability for death Factor 14 Death return
[0033] Factor number Factor name Factor 15 Whether it contains the syndrome Factor 16 Number of cases Factor 17 Whether the middle disease is paid multiple times Factor 18 Whether the disease is grouped Factor 19 Number of moderate group Factor 20 Number of moderate benefit payments Factor 21 Interval between multiple claims for moderate illness Factor 22 Moderate Premium Waiver
[0034] Factor number Factor name Factor 23 Is it mild Factor 24 Number of mild cases Factor 25 Whether the mild illness is paid multiple times Factor 26 Whether the mild disease is grouped Factor 27 Number of mild cases Factor 28 Interval between multiple claims for mild illness Factor 29 Number of minor benefits Factor 30 Waiting period (days) Factor 31 Proportion of mild cases Factor 32 Premium Waiver for Mild Cases
[0035] For example, the dimension of underwriting conditions: combined with the form of critical illness insurance products, the underwriting conditions of critical illness insurance are refined into a scoring factor 33-factor 34, as shown in the following table.
[0036] Factor number Factor name Factor 33 Number of liability exemption clauses Factor 34 Health notification score
[0037] For example, the rate dimension: rate is a key factor in measuring critical illness insurance products. The critical illness insurance rate is refined into a scoring factor 35-factor 37, as shown in the following table.
[0038] Factor number Factor name Factor 35 Premium standard (male) Factor 36 Premium standard (female) Factor 37 Average rate for men and women
[0039] Factor quantification step: quantify the scoring factor;
[0040] The value of a factor generally has two forms, one is non-numerical and the other is numerical.
[0041] (1) For non-numerical factors, because the results are expressed in words, such as the factor "Is serious illness grouped", its content is "Yes" or "No". When calculating the score, the content of the factor needs to be Quantify.
[0042] (2) For numerical factors, since the dimensions of each factor are not necessarily the same, in order to reduce the impact of different dimensions on the results, the factors need to be quantified and unified. Combining the characteristics of each factor, the quantification rules are also different.
[0043] For example, use F1, F2...Fn to represent factor quantization scores, F i , I=1, 2,..., 37, representing the quantitative scores of factor 1-factor 37.
[0044] For example, the quantification of coverage is shown in the following table:
[0045] Factor number Factor name Quantitative score F Factor 1 Number of serious illnesses F1 Factor 2 Whether the serious illness is paid multiple times F2 Factor 3 Whether the serious illness is grouped F3 Factor 4 Number of critical illness groups F4 Factor 5 Number of benefits F5 Factor 6 Interval between multiple claims for critical illness F6 Factor 7 Whether malignant tumors are grouped separately F7 Factor 8 Critical Illness Waiver F8
[0046] Factor number Factor name Quantitative score F Factor 9 Whether it contains specific diseases F9 Factor 10 Number of specific diseases F10 Factor 11 Whether it contains children's specific diseases F11 Factor 12 Number of children with specific diseases F12 Factor 13 Liability for death F13 Factor 14 Death return F14
[0047] Factor number Factor name Quantitative score F Factor 15 Whether it contains the syndrome F15 Factor 16 Number of cases F16 Factor 17 Whether the middle disease is paid multiple times F17 Factor 18 Whether the disease is grouped F18 Factor 19 Number of moderate group F19 Factor 20 Number of moderate benefit payments F20 Factor 21 Interval between multiple claims for moderate illness F21 Factor 22 Moderate Premium Waiver F22
[0048] Factor number Factor name Quantitative score F Factor 23 Is it mild F23 Factor 24 Number of mild cases F24 Factor 25 Whether the mild illness is paid multiple times F25 Factor 26 Whether the mild disease is grouped F26 Factor 27 Number of mild cases F27 Factor 28 Interval between multiple claims for mild illness F28 Factor 29 Number of minor benefits F29 Factor 30 Waiting period (days) F30 Factor 31 Proportion of mild cases F31 Factor 32 Premium Waiver for Mild Cases F32
[0049] For example, the underwriting conditions are as shown in the following table:
[0050] Factor number Factor name Quantitative score F Factor 33 Number of liability exemption clauses F33 Factor 34 Health notification score F34
[0051] For example, the rates are shown in the following table:
[0052] Factor number Factor name Quantitative score F Factor 35 Premium standard (male) F35 Factor 36 Premium standard (female) F36 Factor 37 Average rate for men and women F37
[0053] Weighting step: assign factor weight to the quantified scoring factor;
[0054] In each dimension, each factor plays a different role in the evaluation of insurance types. According to the importance, each factor is given a certain weight. The factor weight is expressed as W i , I=1, 2,..., 37, representing the weight of factor 1-factor 37. 0≤W i ≤1, and the sum of factor weights in each dimension is equal to 1, that is:
[0055]
[0056] For example, the weighting of coverage is shown in the following table:
[0057] Factor number Factor name Quantitative score F Weight W Factor 1 Number of serious illnesses F1 W1 Factor 2 Whether the serious illness is paid multiple times F2 W2 Factor 3 Whether the serious illness is grouped F3 W3 Factor 4 Number of critical illness groups F4 W4 Factor 5 Number of benefits F5 W5 Factor 6 Interval between multiple claims for critical illness F6 W6 Factor 7 Whether malignant tumors are grouped separately F7 W7 Factor 8 Critical Illness Waiver F8 W8
[0058] Factor number Factor name Quantitative score F Weight W Factor 9 Whether it contains specific diseases F9 W9 Factor 10 Number of specific diseases F10 W10 Factor 11 Whether it contains children's specific diseases F11 W11 Factor 12 Number of children with specific diseases F12 W12 Factor 13 Liability for death F13 W13 Factor 14 Death return F14 W14
[0059] Factor number Factor name Quantitative score F Weight W Factor 15 Whether it contains the syndrome F15 W15 Factor 16 Number of cases F16 W16 Factor 17 Whether the middle disease is paid multiple times F17 W17 Factor 18 Whether the disease is grouped F18 W18 Factor 19 Number of moderate group F19 W19 Factor 20 Number of moderate benefit payments F20 W20 Factor 21 Interval between multiple claims for moderate illness F21 W21 Factor 22 Moderate Premium Waiver F22 W22
[0060] Factor number Factor name Quantitative score F Weight W Factor 23 Is it mild F23 W23 Factor 24 Number of mild cases F24 W24 Factor 25 Whether the mild illness is paid multiple times F25 W25 Factor 26 Whether the mild disease is grouped F26 W26 Factor 27 Number of mild cases F27 W27 Factor 28 Interval between multiple claims for mild illness F28 W28 Factor 29 Number of minor benefits F29 W29 Factor 30 Waiting period (days) F30 W30 Factor 31 Proportion of mild cases F31 W31 Factor 32 Premium Waiver for Mild Cases F32 W32
[0061] For example, the weighting of underwriting conditions is shown in the following table:
[0062] Factor number Factor name Quantitative score F Weight W Factor 33 Number of liability exemption clauses F33 W33 Factor 34 Health notification score F34 W34
[0063] For example, the weighting of rates is shown in the following table:
[0064] Factor number Factor name Quantitative score F Weight W Factor 35 Premium standard (male) F35 W35 Factor 36 Premium standard (female) F36 W36 Factor 37 Average rate for men and women F37 W37
[0065] Scoring steps: calculate the score of each dimension;
[0066] Specifically, for example, let B1, B2, and B3 represent the score of each dimension, the calculation method is as follows:
[0067]
[0068] Dimension weighting step: assign weights to the scores of each dimension (V1, V2 and V3);
[0069] According to the importance of each dimension in the product score, different weights are assigned, respectively V 1 , V 2 , V 3 , 0≤V j ≤1.
[0070] Calculation steps: Calculate the product score, where the weighted sum of the scores of the three dimensions is performed to obtain the product score.
[0071] Combine dimension score B and dimension weight V to calculate product score:
[0072]
[0073] According to another preferred embodiment of the present invention, there is also provided a critical illness insurance product scoring device based on factorized rules, which is used to implement the critical illness insurance product scoring method based on the aforementioned factorized rules.
