Fig. 1 is a schematic flow chart of an inventive online education topic generation method for generating topics online through a topic library in a course of writing a lecture, as shown in fig. 1, the method includes the following steps:

s1, receiving a question order and a question writing position;

in the invention, the topic order can be one or more topics intercepted by a teacher through screenshot, can also be one or more topics edited or copied by the teacher through a document, and can also be one or more topics described by the teacher through keywords. The content of the topic order can be specifically pictures or texts. The title authoring location can be marked by placing a placeholder at the authoring location of the handout. For example, if a teacher needs to add an item at a designated position of a current page of an on-line lecture in a lecture system, the teacher may place a mouse at the designated position to generate a placeholder and submit an item order through an order placement page of the lecture system to complete an "order placement" operation of a target title, the lecture system collects and sends an item order and an item writing position input by a user to an item library system, and the item library system receives the item order and the item writing position.

For example, in writing a complete lecture, referring to fig. 2 and 3, the specific process of order collection includes: the teaching and research teacher uploads the subject order to be produced in the current lecture to the question bank system through the lecture system, the question bank system stores and generates the ID of the subject order, and then the ID of the subject order is returned to the lecture system, during the period, a plurality of subject orders can be received and correspondingly generated to form a plurality of subject order IDs, meanwhile, the lecture system judges whether the subject needs to be input in real time, when the lecture system receives a command for inputting the subject, the subject order collecting device collects all the subject IDs to be produced in the current lecture to generate order IDs, and the order IDs are sent to the question bank system for subject production.

S2, generating a target title according to the title order;

illustratively, as shown in fig. 4, the present step includes:

s21, analyzing the question order into question stem and question type constraint modes;

in the present invention, the question stem is the question content, and the question type constraint mode is a constraint mode for the question type structure, and specifically includes: single choice question constraint mode, multiple choice question constraint mode, blank filling question constraint mode, judgment question constraint mode and subjective question constraint mode. The radio topic constraint mode may specifically include: the options only include one correct option, and the multiple choice question constraint mode may specifically include: the options include at least two correct options, and the constraint mode of the gap filling question may specifically include: the part to be filled in the space, the judgment subject constraint mode may specifically include a judgment result part, and the subjective subject constraint mode may specifically include: and (4) a problem part.

In the analysis process, the question order can be divided into question stems and question type constraint modes, and then the question type constraint mode belongs to which specific question type constraint mode is judged according to the specific structure of the question type constraint mode. For example, for the choice question, the question order may be divided into a question stem, options and the number of answer options, if the number of answer options is one, the question type constraint mode of the question order is a single choice question constraint mode, and if the number of answer options is two or more, the question type constraint mode of the question order is a multiple choice question constraint mode.

S22, searching whether the question bank comprises questions corresponding to the question stem and the question type constraint mode;

specifically, the question corresponding to the question stem and the question type constraint mode can be searched in the question bank system.

And S23, if the question bank does not have questions corresponding to the question stem and question type constraint modes, generating target questions according to the question stem and question type constraint modes.

For example, the generating of the target topic according to the topic stem and topic type constraint manner may specifically be generating topic field information according to the topic stem and topic type constraint manner. For example, a question order including a question stem and a single choice question constraint mode can generate question field information of the question stem, the choice, the answer, the analysis and the answer according to the question type constraint mode that the number of the question stem and the answer choice is one. The method comprises the steps of ordering questions in question stem and reading comprehension question restriction modes, and generating question field information of articles, answers of big questions, answers of small questions and answers according to the question stem and reading comprehension question restriction modes.

Further, in order to improve the accuracy of the topic production, the topic may be audited and corrected after the topic is generated, and specifically, after step S23, the method further includes:

s24, submitting the target title for examination;

specifically, the question bank system can submit the generated target question to an audit page and display the production progress or state of the target question, such as production state, audit state, error correction state, audit pass state, and the like. The teacher can check and correct the target subject through the check page.

If the examination is passed, the target title is marked as passed;

if the audit is not passed, receiving error correction of the target title, submitting the error-corrected target title to the audit until the error-corrected target title passes the audit, and identifying the target title as the audit is passed; in this step, some target topics may need to be audited and passed after multiple audits and error corrections, and the target topics are identified as being audited and passed after the final audits are passed.

For example, in the title auditing process, referring to fig. 2 and 5, the progress or state of the production titles of the lecture system and the title library system can be synchronized through the title state notification device, such as the production state in production, in auditing, in error correction, in auditing pass, and the like. Each key process node of the question produced by the question bank system updates the production progress or state of the question, when the question state changes to 'check pass', the question bank system completes the production of the question, and at the moment, the question state informing device informs the lecture system of reflowing the question content.

In the invention, in order to accumulate the teaching data assets, the newly produced target questions passing the examination and verification can be further stored in the question bank database. If the question is needed subsequently, the question can be directly extracted from the question bank database, and meanwhile, the good-quality question can be precipitated.

And S25, if the question bank has questions corresponding to the question stem and the question type constraint mode, taking the questions as target questions.

In step S25, if the question corresponding to the question stem and the question type constraint method can be searched in the question bank in synchronization with step S23, the question can be used as the target question without reproducing the target question.

S3, loading the target topic to the topic writing position.

Specifically, for questions which do not correspond to the question stem and question type constraint mode in the question bank, the target questions generated according to the question stem and question type constraint mode can be loaded to the question writing position, and the target questions are identified and approved. And directly loading the question serving as a target question to the question writing position for the question which is in the question library and corresponds to the question stem and question type constraint mode.

Specifically, in the loading process, after receiving the notification that the question of the question state notification device passes the examination, the lecture system calls the question reflux device to reflux the questions produced by the question bank system to the lecture system, and the lecture system automatically loads the lecture document questions to the lecture document title writing position. Referring to fig. 2 and 6, the topic reflowing device determines the topic type according to the topic type constraint condition, and then retrieves the topic field information corresponding to the topic produced by the topic library system from the topic library system, for example, if the topic type of the current topic is a selected topic, the topic reflowing device will retrieve the topic field information of the selected topic, such as the topic stem, option, answer, analysis, solution, etc., of the selected topic, and if the topic type is a reading comprehension, the topic reflowing device will retrieve the topic field information of the reading comprehension article, big topic, small topic, answer, solution, etc. Finally, the title reflow device adjusts the format of the retrieved title field information according to the title type and reflows the adjusted title field information to the position of the title placeholder in the presentation system.

By the method and the system, when a teacher writes a lecture and encounters a question which is not in a question bank, the teacher directly puts an order for the question which is produced in the question bank into the question bank system, and meanwhile, a placeholder of the question is generated in a written lecture document, so that the teacher can continuously set relevant question attributes for the question, such as the purpose of the question, the difficulty of the question, the source of the question and the like, without waiting for the completion of the production of the question. When the question bank system receives the question order, the question bank system produces the question, the question needs to be checked and corrected for many times during the production, and finally after the production is finished, the produced question content can be returned to the position of the position occupied by the position element in the lecture document by the question returning device. Thus, the automatic entry of the title is completed.
