[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented.

[0021] One embodiment of the present invention relates to a test question generation method with bullet screen, which is applied to a test question generation system, such as Figure 1 As shown, this embodiment specifically includes the following steps.

[0022] Step 101: Obtain the user's learning goal, and take the set of knowledge points corresponding to the learning goal as the first set.

[0023] Specifically, the user in this embodiment refers to the user of the test question generation system, generally a student. In this embodiment, step 101 obtains the user's learning goal in order to clarify the scope of knowledge that the user expects to learn, and converts it into a set of knowledge points that can be processed by the test question generation system. In this embodiment, the learning goal can be obtained through the user's interactive behavior in the test question generation system. For example, a selection interface can be set in the test question generation system to provide users with the choice of learning goals. The user selects a specific course or a specific chapter of a specific course in the selection interface. The process of the system obtaining the course or chapter information selected by the user is the process of the system obtaining the learning goal. Alternatively, the learning goal can also be set directly by the user in the form of text input. For example, the user enters "prepare for the probability theory part of postgraduate entrance examination mathematics" as a specific goal, and the input content is the learning goal. After obtaining the learning goal, the set of knowledge points corresponding to the learning goal is used as the first set. The knowledge point confirmation of the learning goal can be obtained based on keyword retrieval. By retrieving keywords related to the learning goal, matching knowledge points are retrieved, thereby constructing the first set.

[0024] In one example, the specific execution steps of step 101 may be: obtaining the learning objectives selected by the user in the preset learning outline; extracting the knowledge points corresponding to the learning objectives in the preset database to construct a first set.

[0025] Specifically, in the test question generation system of this embodiment, a series of learning outlines will be provided to the user, and these outlines cover different subjects, courses, themes or learning modules. The user can select the courses, themes or learning modules that he wants to learn from these preset learning outlines according to his needs and interests, and the test question generation system determines the learning objectives according to the user's selection. At the same time, the test question generation system will store the user's selection operation in the user's personal information or learning process record, thereby associating the user with the learning outline, so that after the knowledge points corresponding to this part of the learning objectives are learned, the system will mark them as knowledge points that the user has mastered.

[0026] After obtaining the learning objectives, the learning objectives are mapped to specific knowledge points in the preset database through information retrieval and extraction technology. This process can use keyword matching, semantic analysis or data mining algorithms, etc., and this embodiment does not make specific restrictions on this. For example, after the user selects "advanced mathematics" as the learning objective, the system will search for information related to advanced mathematics in the database, which may include course chapters, specific mathematical concepts, theorems, formulas, examples, etc. Knowledge points such as "limits of functions", "calculation of derivatives", and "application of integrals" related to "advanced mathematics" in the preset database are extracted through keyword matching, semantic analysis or data mining algorithms, and the extracted knowledge points will be sorted and constructed into a first set. It should be noted that each knowledge point may be added with unique identifiers, category labels, and other information to facilitate subsequent storage, query, and use.

[0027] Step 102: Determine the knowledge points that the user has mastered, and use the set of the mastered knowledge points as the second set.

[0028] Specifically, this embodiment can determine the knowledge points that the user has mastered by obtaining the user's learning records on the test question generation system or other learning platforms, and map the mastered knowledge points to the second set. When determining whether a knowledge point is a knowledge point that the user has mastered, it can be done according to a specified rule, for example, the correct answer rate of questions with the same knowledge point exceeds 80%, or the number of correct answers to questions with the same knowledge point exceeds a preset number. This application does not specifically limit the rules for determining the knowledge points that the user has mastered.

[0029] In one example, step 102 may specifically include: collecting the user's historical answer data, and analyzing and evaluating the historical answer data using a first evaluation rule; wherein the first evaluation rule is used to evaluate whether the knowledge point has been mastered by the user; and adding the knowledge points in the historical answer data that are evaluated as having been mastered to a second set.

[0030] Specifically, the historical answer data in this embodiment includes but is not limited to historical test scores, homework completion, online practice answer data, etc. The system obtains historical answer data through the user answer records stored in the database. These records contain detailed information on tests or homeworks completed by users at different time points, for example, the user's answers to different questions in a math test, including answers, answer time and other data. For these acquired data, the first evaluation rule is used to evaluate the actual situation of each knowledge point in the historical answer data to determine whether the knowledge point has been mastered. The first evaluation rule of this embodiment can be determined based on the score threshold, answer accuracy, and homework time, and is not specifically limited here. Taking the historical test score as an example, if the score is set to 80 points or above, and the answer accuracy rate is high on the questions of the same knowledge point, it is considered that the user has mastered the knowledge point. For homework and online practice data, factors such as answer accuracy, completion time, and the number of times the prompt is viewed are comprehensively considered. For example, if the user's answer accuracy rate reaches more than 90% in multiple homework and exercises related to a certain knowledge point, and the average completion time is within a reasonable range, and the number of times the prompt is viewed is small, the system determines that the user has mastered the knowledge point.

[0031] After comprehensive analysis and judgment of various types of data, the knowledge points determined to be mastered by the user are organized into a second set, and the set is regularly updated according to the user's new learning data to ensure that it can accurately reflect the user's knowledge mastery dynamics. For each historical question, it is analyzed according to the pre-set first evaluation rule. For example, for multiple-choice questions, if the user's answer is correct, a certain score may be obtained; for short-answer questions and essay questions, in addition to judging whether the answer is correct, the completeness, accuracy and logic of the answer may also be considered. For different types of questions, different scoring calculation methods and evaluation rules can be used, and this embodiment does not make specific restrictions on this. In addition, the first evaluation rule can also comprehensively consider various factors and assign different weights. For example, the correct answer rate accounts for 70% of the weight, the answer time accounts for 20% of the weight, and the use of prompt tools accounts for 10% of the weight, and this embodiment does not make specific restrictions on this.

[0032] Step 103: Generate a test volume according to the first set and the second set and provide it to the user.

[0033] Specifically, based on the two sets determined in step 101 and step 102, a test paper that meets the user's current knowledge status is generated and presented to the user. The acquisition of test questions in the test paper mainly depends on a pre-built test question bank, which contains questions corresponding to various knowledge points, and each question is marked with relevant knowledge points, difficulty levels, question types and other information. The system can select a certain number of questions of different difficulty levels from the question bank based on the difference between the first set and the second set to ensure a comprehensive examination of the knowledge point. At the same time, the difficulty of the questions can also be adjusted in combination with the user's overall learning progress and goals. By combining and sorting the selected questions, a complete test paper is generated, and the test paper data is sent to the user terminal device through the network interface of the learning platform and presented to the user in the form of a visual interface.

[0034] In one example, step 104 may specifically include: screening out basic test questions from a pre-constructed test question bank based on the knowledge points included in the union of the first set and the second set; wherein each basic test question has a mapping relationship with at least one knowledge point; and selecting basic test questions that meet the target number to generate a test paper.

[0035] Specifically, the test question bank in this embodiment is a resource library that pre-stores a large number of test questions, and each test question has a clear mapping relationship with one or more knowledge points. This means that each test question is marked with the knowledge point it involves, so that it can be retrieved according to different knowledge screening requirements. The system will filter out basic test questions in the pre-constructed test question bank according to the union of the first set and the second set. Specifically, the first set stores the knowledge points corresponding to the user's learning goals, and the second set stores the knowledge points that the user has mastered. Their union contains all the knowledge points that need to be considered in the user's learning process. The test question generation system will extract the information of the first set and the second set from the user's learning archives, and at the same time, access the pre-constructed test question bank, which is stored in the database of the system and contains various types of test questions and their mapping relationships with knowledge points. For example, for the knowledge point of "derivative calculation of function", it may be mapped to multiple basic test questions. Similarly, a test question may also involve multiple knowledge points. The test question generation system will filter out relevant basic test questions in this question bank based on the knowledge points contained in the union. The screening process can traverse each test question in the test question bank, or use a more efficient index search algorithm to quickly find related basic test questions based on the knowledge point index.

[0036] After the screening is completed, the test questions that meet the target number are selected from the basic test questions that have been screened out to generate the final test paper. The determination of the target number can be based on the user's study arrangement, for example, the number of questions included in this test paper is determined according to the user's planned study time, study stage or the default setting of the system. Assuming that the target number is 30 questions, and there are 80 basic test questions screened out, the system can use a random selection algorithm to ensure that each generated test paper has a certain degree of randomness to avoid the user's predictability of the test content; or weighted selection is performed based on the importance of different knowledge points, the difficulty level of the test questions and other factors to ensure that the test paper can comprehensively examine the user's knowledge mastery. In the selection process, the system will pay attention to the diversity and coverage of the test questions to ensure that the test paper contains different types of questions, covering different knowledge fields and difficulty levels. This embodiment does not specifically limit the method and number of selecting test questions.

[0037] The test paper generated in the above manner in this embodiment can not only fully cover the important knowledge points in the user's learning process, but also be reasonably adjusted according to the user's knowledge mastery, providing a basis for subsequent learning evaluation and barrage prompts during the user's answering process, thereby improving the effectiveness of the test and the user's learning experience.

[0038] Step 104: monitor the user's answering situation, and when the target knowledge point corresponding to the first test question in the test paper being answered by the user belongs to the first set but not to the second set, prompt the user with the target knowledge point in the form of a bullet screen.

[0039] Specifically, in order to provide timely help to the user, in the process of answering questions by the user, the system of this embodiment will monitor the knowledge points involved in the question currently being answered by the user in real time, so as to provide timely help when the user encounters difficulties. Monitoring the user's answering situation can be achieved through real-time interaction between the user's answering interface and the system background. When the user starts to answer a test question in the test paper, the test question is taken as the first test question, and the corresponding question information (including the knowledge points involved) is transmitted from the background database to the answering interface. At the same time, the answering interface can also feed back the user's answering operation data (such as answering time, mouse click position, etc.) to the background system. When it is detected that the target knowledge point corresponding to the first test question in the test paper being answered by the user belongs to the first set but not the second set, the target knowledge point is prompted to the user in the form of bullet screen.

[0040] In an example, Figure 2 As shown, the monitoring of the user's answering situation in step 104 includes:

[0041] Step 201: Obtain a first test question that the user is answering, and determine a target knowledge point corresponding to a mapping relationship of the first test question.

[0042] Specifically, when the user starts answering questions on the test paper, the system starts monitoring and first obtains the information of the first test question that the user is answering. After the user clicks to start answering questions, the answering interface sends the information of the first test question that the user is processing to the background. The background stores detailed information of each test question in the test paper, covering all aspects of the test question. For example, a test question about "properties of elements in the periodic table of chemical elements" may store information including question number, question stem, possible options (for multiple-choice questions), correct answers, and other related data. At the same time, the system stores the mapping relationship between the first test question and the knowledge point. At this time, for the above-mentioned test question about "properties of elements in the periodic table of chemical elements", its mapping relationship will clearly indicate that it involves knowledge points such as "periodic law of elements" and "relationship between atomic structure and properties of elements". The system will search in the database according to the unique identifier of the first test question that the user is answering, extract the detailed information of the test question, and then find the corresponding target knowledge point according to the mapping relationship.

[0043] Step 202: Compare the target knowledge point with the knowledge points in the first set and the second set to determine whether the target knowledge point satisfies the condition of belonging to the first set but not belonging to the second set.

[0044] Specifically, the test question generation system will compare the target knowledge points corresponding to the first test question that the user is answering with the first set and the second set stored in the user's learning archive. Taking the example just now, assuming that the user is studying chemistry, the first set may contain knowledge points such as "periodic law of elements", "formation of chemical bonds", and "balance of chemical reactions", which are the knowledge that the user expects to master by selecting a chemistry course or setting a learning goal; the second set may contain "basic chemical concepts" and "symbols and names of common elements" and other knowledge points that the user has already mastered. The system will compare the target knowledge points extracted from the first test question being answered, such as "periodic law of elements", with the first set and the second set. Through the set operation algorithm, first check whether the first set contains "periodic law of elements", and if so, check whether the second set does not contain the knowledge point. Through this comparison operation, the system can determine whether the target knowledge points involved in the test question that the user is answering belong to the first set but not the second set. For example, if "Periodic Law of Elements" belongs to the first set but not in the second set, this means that the user is dealing with a knowledge point that is part of the learning goal but has not yet been mastered. At this time, the system can judge that the user may need help, laying the foundation for providing help to the user in the form of barrage in the future, thereby achieving personalized learning assistance and improving the user's learning effect and answering experience.

[0045] In another example, before prompting the target knowledge point to the user in the form of a bullet screen, the steps of this embodiment also include: obtaining the average answer time corresponding to the first test question.

[0046] On this basis, the step 104 of prompting the target knowledge point to the user in the form of bullet screen may include:

[0047] When the user's answering time for the first test question exceeds the average answering time, the target knowledge point is prompted to the user in the form of a bullet screen.

[0048] Specifically, before considering providing users with prompts of target knowledge points in the form of barrage, the test question generation system needs to obtain the average answer time corresponding to the first test question. The historical question responses of the test question generation system are stored in the database of historical answer data, which contains detailed information on many users completing various test questions at different times, including the answer time they spent on each question. For the first test question, the system will filter out the historical answer time information related to the test question in this database. Taking a test question A on "Application of the Law of Conservation of Momentum in Physical Mechanics" as an example, the system will retrieve the answer time data of all users who have answered the question. For example, if user A takes 10 minutes, user B takes 12 minutes, and user C takes 8 minutes, then the average answer time is 10 minutes, etc.

[0049] When the user starts to answer the first test question, the system will monitor the user's answering time in real time. When the user starts to answer test question A, the system's timing function starts. The system will continue to record the time the user spends on the question and compare it with the calculated average answering time. When the user's answering time on the question exceeds the average answering time, the system will trigger the prompt mechanism. At this time, the system will extract the target knowledge point information related to the test question from the knowledge base. For the "Application of the Law of Conservation of Momentum" test question, its target knowledge point is "Law of Conservation of Momentum". The system will search for key information about "Law of Conservation of Momentum" from the knowledge base, which may include "The formula of the law of conservation of momentum p = mv, the total momentum is conserved when the system is not subject to external forces, and the specific expression is m1v1+m2v2=m1v1'+m2v2' and other contents. The system will organize this information into concise and clear information suitable for presentation in the form of barrage, and then send it to the user's answering interface through the barrage system to provide timely help to the user.

[0050] Through the method of this embodiment, timely help can be provided to users based on the users' answering time and the average answering time of the questions, avoiding users from spending too much time on a question and getting into trouble. At the same time, help will not be provided too frequently to interfere with the users' normal answering process, which helps to improve the users' learning efficiency and experience.
