[0069]

[0070] Among them, F ai represents the probability that the a-th English test question selected for the first time belongs to the i-th category; S i It means that the F corresponding to the a-th English test question screened out for the first time is calculated according to formula (3). ai Previously, the number of English test questions belonging to the i-th category has been determined; S represents the F corresponding to the a-th English test question screened for the first time calculated according to formula (3) ai Previously, the number of English test questions that have been classified; P at represents the number of times the t-th feature information corresponding to the i-th category question appears in the a-th English test question screened for the first time; m represents the total number of feature information corresponding to the i-th category question;

[0071] When the F ai When the percentage is equal to or greater than 60%, it is considered that the ath English test question screened for the first time belongs to the ith question type; if there is an English test question that belongs to multiple question types, select the F ai The question type corresponding to the maximum value is used as the final type of the a-th English test question screened out for the first time;

[0072] When the F aiWhen it is less than 60%, a new type of question type is formed separately until all the English test questions screened out for the first time are classified, and finally different types of English test questions matching the difficulty level of the learning data record set are screened out.

[0073] The beneficial effects of the above technical solution are as follows: formula (1) is used to obtain the difficulty level of the English test questions in the preset English test question library, the purpose of which is to quantify the difficulty of the English test questions in the preset English test question library through the formula, and also to match the difficulty level of the learning data record set itself in the subsequent process, thereby ensuring the subsequent screening of questions; formula (2) is used to obtain the matching degree value, the purpose of which is to use the matching degree value obtained by the formula to screen the English test questions in the preset English test question library once, and screen out English test questions that match the difficulty level; finally, formula (3) is used to obtain the classification probability value, and the classification probability value can be used to accurately classify the English test questions in the preset English test question library after the first screening, and a second screening is performed according to the classification value, and finally different types of English test questions that match the difficulty level are selected; the above formula and steps increase the accuracy of screening the English test questions in the preset English test question library, and use the two-screening method to make the screened questions more in line with the requirements, and the types of selected questions can be guaranteed to be diversified, and the difficulty is also matched with the difficulty level.

[0106] The beneficial effects of the above technical solution are as follows: formula (1) is used to obtain the difficulty level of the English test questions in the preset English test question library, the purpose of which is to quantify the difficulty of the English test questions in the preset English test question library through the formula, and also to match the difficulty level of the learning data record set itself in the subsequent process, thereby ensuring the subsequent screening of questions; formula (2) is used to obtain the matching degree value, the purpose of which is to use the matching degree value obtained by the formula to screen the English test questions in the preset English test question library once, and screen out English test questions that match the difficulty level; finally, formula (3) is used to obtain the classification probability value, and the classification probability value can be used to accurately classify the English test questions in the preset English test question library after the first screening, and a second screening is performed according to the classification value, and finally different types of English test questions that match the difficulty level are selected; the above formula and steps increase the accuracy of screening the English test questions in the preset English test question library, and use the two-screening method to make the screened questions more in line with the requirements, and the types of selected questions can be guaranteed to be diversified, and the difficulty is also matched with the difficulty level.

[0107] It can be seen from the contents of the above embodiments that the method and system for automatically generating English questions obtains the English history learning data records of the preset test object, and processes the data type content of the English history learning data records, thereby determining a number of English grammar learning data records, a number of English pronunciation learning data records, and a number of English vocabulary learning data records, and determines the difficulty level corresponding to each of the English grammar learning data records, the English pronunciation learning data records, and the English vocabulary learning data records, and divides the English grammar learning data records, English pronunciation learning data records, and English vocabulary learning data records with the same difficulty level into the same learning data record set, and then selects a number of English test questions matching the learning data record set from the preset English test question library. Different types of English test questions are selected, and according to the duration of the test on the preset test object, a corresponding number of different types of English test questions are selected from the several different types of English test questions to form an English test question volume; it can be seen that the English question automatic generation method and system can form a corresponding learning data record set according to the different difficulty levels of grammar, pronunciation and vocabulary of the English historical learning data records of the preset test object, and then filter out different types of English test questions from the preset English test question library according to the learning data record set to form a suitable English test question volume, so as to intelligently generate test questions that match the preset test object's historical learning records and improve the automation and reliability of English test question formation.
