Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
FIG. 1 is a flow chart illustrating a method of processing questionnaire data according to an exemplary disclosed embodiment. As shown in fig. 1, the processing method of questionnaire data includes the following steps:
and S11, obtaining answer sheet data of the user to the questionnaire.
The questionnaire can be an electronic questionnaire or a paper questionnaire. When the questionnaire is a paper questionnaire, character recognition or fill-in area recognition can be performed on the answer content of the questionnaire to obtain the answer data. In a possible implementation mode, the questionnaire can be issued to the user in a telephone questionnaire mode, and answer data of the user is collected in a voice recognition mode.
The answer sheet data is answer answers of users to the questionnaires, and can be subjective answers, namely open answers without standard options given in the question stem, or objective answers, namely optional answers.
Optionally, the questionnaire consists of questions that distinguish fraudulent ones of the sample users above a distinguishing threshold. Discrimination characterization problems can distinguish between fraudulent and non-fraudulent users by different options.
Wherein the discrimination of the problem is determined by:
for each question, determining the proportion of fraudulent users in the sample users selecting each option under the question; and determining the discrimination of the problem according to the ratio, wherein the ratio of the fraudulent user and the discrimination are in positive correlation.
For example, if a question has A, B, C, D four options, and the number of users with fraud is up to 60% among sample users who have selected C option, and the number of users with fraud is less than 10% among sample users who have selected A, B, D option, it indicates that the question can be primarily distinguished by "whether or not the C option is selected" whether or not the user will make fraud, and the distinction degree of the question is high. If a question has A, B, C, D four options, but the fraudulent user distributions are even (e.g. all in the interval of 30% -40%) among the sample users selecting which option, it means that the question cannot preliminarily distinguish whether the user will make fraudulent activities by selecting a certain option, and the distinction degree of the question is low.
The questionnaire comprises a testable question and an uncertifiable question, wherein the testable question is a question with standard answers or a question which can be used for distinguishing whether the user answers correctly or not through user characteristics, and the uncertifiable question is a question which cannot be used for distinguishing whether the user answers correctly or not without the standard answers. For example, if the question is the monthly income level of the user, the user can be distinguished whether the user answers correctly by comparing the payroll list of the user with the options selected by the user, and therefore, the question is a testable question; if the question is a risk range that the user can bear, the answer of the question is determined by the subjective feeling of the user and cannot be distinguished, so that the question is an unverifiable question.
For the testimonial question, the answer sheet data is obtained by the following method: and determining whether the answer of the sample user is matched with the characteristic information of the sample user, if the answer is matched with the characteristic information, the answer is correct, and if the answer is not matched with the characteristic information, the answer is wrong, wherein the answer data comprises information for representing whether the answer of the user is correct, and the characteristic information is extracted from user data submitted when the sample user transacts the business.
For example, if the question is "which of the following is your monthly income: A. below 4000, B, 4000-8000, C, 8000-13000, and D, 13000 or above ", the user selects the option C, and the monthly income of the user is 4500 yuan actually extracted from the payroll details submitted by the user, and if the payroll interval does not belong to the option C, the user is indicated to have made an incorrect answer.
For the non-corroborable question, the answer sheet data includes a selection item for each option provided by the user for the question.
And S12, inputting the answer sheet data into a data processing model to obtain a data processing result output by the data processing model.
The data processing result comprises a data tag used for representing the credibility size of the user.
The data processing model is obtained by training according to the actual data labels of the sample users and the answer sheet data samples of the questionnaires of the sample users.
The sample user may be a user who has transacted a service before, and when the user performs an actual service operation after processing the user answer data, the user may also become a sample user. Thus, with the actual sample data support, the selection of questionnaires and the data processing capabilities of the data processing model are constantly optimized as the number of sample users increases.
By the technical scheme, the answer sheet data of the user can be processed through the data processing model, the data tag representing the credibility of the user is obtained, and the problems of low accuracy and low efficiency in manual answer sheet data processing can be solved.
FIG. 2 is a flow chart illustrating another method of processing questionnaire data according to an exemplary disclosed embodiment. As shown in fig. 2, the processing method of the questionnaire data includes the following steps:
and S21, obtaining answer sheet data of the user to the questionnaire corresponding to the service type of the user.
The questionnaire can be an electronic questionnaire or a paper questionnaire. When the questionnaire is a paper questionnaire, character recognition or fill-in area recognition can be performed on the answer content of the questionnaire to obtain the answer data. In a possible implementation mode, the questionnaire can be issued to the user in a telephone questionnaire mode, and answer data of the user is collected in a voice recognition mode.
The answer sheet data is answer answers of users to the questionnaires, and can be subjective answers, namely open answers without standard options given in the question stem, or objective answers, namely optional answers.
Optionally, the questionnaire consists of questions that distinguish fraudulent ones of the sample users above a distinguishing threshold. Discrimination characterization problems can distinguish between fraudulent and non-fraudulent users by different options.
Wherein the discrimination of the problem is determined by:
for each question, determining the proportion of fraudulent users in the sample users selecting each option under the question; and determining the discrimination of the problem according to the ratio, wherein the ratio of the fraudulent user and the discrimination are in positive correlation.
For example, if a question has A, B, C, D four options, and the number of users with fraud is up to 60% among sample users who have selected C option, and the number of users with fraud is less than 10% among sample users who have selected A, B, D option, it indicates that the question can be primarily distinguished by "whether or not the C option is selected" whether or not the user will make fraud, and the distinction degree of the question is high. If a question has A, B, C, D four options, but the fraudulent user distributions are even (e.g. all in the interval of 30% -40%) among the sample users selecting which option, it means that the question cannot preliminarily distinguish whether the user will make fraudulent activities by selecting a certain option, and the distinction degree of the question is low.
The questionnaire comprises a testable question and an uncertifiable question, wherein the testable question is a question with standard answers or a question which can be used for distinguishing whether the user answers correctly or not through user characteristics, and the uncertifiable question is a question which cannot be used for distinguishing whether the user answers correctly or not without the standard answers. For example, if the question is the monthly income level of the user, the user can be distinguished whether the user answers correctly by comparing the payroll list of the user with the options selected by the user, and therefore, the question is a testable question; if the question is a risk range that the user can bear, the answer of the question is determined by the subjective feeling of the user and cannot be distinguished, so that the question is an unverifiable question.
For the testimonial question, the answer sheet data is obtained by the following method: and determining whether the answer of the sample user is matched with the characteristic information of the sample user, if the answer is matched with the characteristic information, the answer is correct, and if the answer is not matched with the characteristic information, the answer is wrong, wherein the answer data comprises information for representing whether the answer of the user is correct, and the characteristic information is extracted from user data submitted when the sample user transacts the business.
For example, if the question is "which of the following is your monthly income: A. below 4000, B, 4000-8000, C, 8000-13000, and D, 13000 or above ", the user selects the option C, and the monthly income of the user is 4500 yuan actually extracted from the payroll details submitted by the user, and if the payroll interval does not belong to the option C, the user is indicated to have made an incorrect answer.
For the non-corroborable question, the answer sheet data includes a selection item for each option provided by the user for the question.
Optionally, the questionnaire is composed of questions that the discrimination of fraudulent users of the sample users under the service type is higher than a first discrimination threshold, or the questionnaire is composed of questions that the discrimination of fraudulent users of the sample users under all the service types is higher than a second discrimination threshold, where the second discrimination threshold is smaller than the first discrimination threshold.
It should be noted that a service problem pool may be generated in advance for each service, where a problem in the service questionnaire pool is composed of problems that the discrimination of a fraudulent user among sample users in the service type is higher than a first discrimination threshold; a general question pool may also be generated, the questions in the general questionnaire pool consisting of questions that the degree of discrimination for fraudulent ones of the sample users under all traffic types is higher than the second degree of discrimination threshold. When the questionnaire is generated, a preset number of questions can be extracted from a service question pool corresponding to the service type of the user to form an answer sheet, a preset number of questions can be extracted from a common question pool to form an answer sheet, or a preset number of questions can be mixed and extracted from the service question pool and the common question pool according to a certain proportion to form an answer sheet.
And S22, inputting the answer sheet data into a data processing model corresponding to the service type to obtain a data processing result output by the data processing model.
The data processing result comprises a data tag used for representing the credibility size of the user.
The data processing model is obtained by training according to the actual data labels of the sample users and the answer sheet data samples of the questionnaires of the sample users.
The sample user may be a user who has transacted a service before, and when the user performs an actual service operation after processing the user answer data, the user may also become a sample user. Thus, with the actual sample data support, the selection of questionnaires and the data processing capabilities of the data processing model are constantly optimized as the number of sample users increases.
Optionally, the answer data samples of the sample users may be processed according to the data processing model to obtain an intermediate value of a processing result output by the data processing model, and it is determined whether a proportion of fraudulent users among the sample users in a preset value interval of the intermediate value is higher than a preset proportion threshold value, if the proportion of the fraudulent users is lower than the preset proportion threshold value, the questions in the questionnaire are re-determined, and the data processing model is generated according to the re-determined questionnaire through retraining.
For example, after the data processing model processes the answer sheet data sample of the sample user, a processing intermediate value of the sample user can be obtained, wherein the intermediate value can be any value of 1-100, and the interval from low to high is 1: 1-10, interval 2: 11-20, interval 3: 21-30, interval 4: 31-40, interval 5: 41-50, interval 6: 51-60, interval 7: 61-70, interval 8: 71-80, interval 9: 81-90, interval 10: and the ten intervals of 91-100 can respectively determine the proportion of the fraudulent users in each interval, if the interval with the highest proportion of the fraudulent users is lower than a preset proportion threshold, the recognition degree of the result output by the data processing model to the fraudulent users is not high, the problems in the questionnaire need to be determined again, and the data processing model is generated again according to the re-determined questionnaire.
It should be noted that, for the data processing model with the highest recognition degree of the fraudulent user, the highest proportion of fraudulent users can be distinguished in the interval with a small number of people, for example, there are 600 sample users, where only the median value of 20 sample users falls into the interval 3, but the number of fraudulent users in the 20 sample users is up to 19, and then the data processing model can judge whether the user is likely to have fraudulent behaviors by whether the data tag value of the user is in the interval 3, that is, the recognition degree of the data processing model for the fraudulent user is very high; if there are 600 users, 400 of them fall into the interval 7, and the number of the fraudulent users is 400, although the proportion of the fraudulent users in the interval is also high (66.7%), there are also a large number of users who are not fraudulent users, and the recognition degree of the model for the fraudulent users is not high. In the actual selection model, whether an interval lower than a preset number threshold exists or not can be judged, and then whether the proportion of fraudulent users in the interval is higher than a preset proportion threshold or not can be judged, so that whether the problems in the questionnaire need to be determined again or not can be determined. The optimization mode can also be realized through an optimization model, and the optimal questionnaire and the data processing model are automatically determined by controlling the number of sample users and the proportion of fraudulent users in each interval.
By the technical scheme, the answer sheet data of users with different service types can be processed through the data processing models with different service types, the data tags representing the credibility of the users can be obtained, the problems of low accuracy and low efficiency in manual answer sheet data processing can be solved, the answer sheet data of the users can be distinguished and processed according to different service types, and the flexibility is high.
