FIG. 1 illustrates an implementation scenario diagram according to one embodiment disclosed herein. In this implementation scenario, the online learning system may provide a service for a user (student) to learn about learning content of a knowledge point for which learning needs to be consolidated, and provide a service for the user to supplement note content understood by the user for the learning content, which is hereinafter referred to as a target service for convenience of description. The knowledge points that the user needs to consolidate learning may include knowledge points related to the error, wherein the knowledge points are included in the knowledge points (teaching material knowledge points) of the teaching material used by the user.

As shown in fig. 1, the process of providing the target service for the user by the online learning system may be divided into two stages, where, in the first stage, for the user to record the error, a corresponding relationship between the error and the knowledge points of the teaching materials used by the user is established in the recording process; and step two, providing target services for the user according to the user requirements.

And a first stage, acquiring a wrong question (for example, a target wrong question) of a target user, wherein the target wrong question is labeled with a plurality of knowledge points in advance, the knowledge points are labeled by a professional teacher team aiming at the target wrong question, and the professional teacher team can label corresponding knowledge points aiming at any question existing on the line. In the embodiments of the present specification, for clarity of description, the knowledge points labeled by the target wrong questions are referred to as wrong question knowledge points.

In one implementation, since the topics on the line relate to multiple versions of teaching materials (that is, the topics may belong to different versions of teaching materials respectively), in order to conveniently and quickly label knowledge points of the topics, and to ensure the accuracy and the universality of the labeled knowledge points, a base tree may be constructed in advance for each subject (or each section of each subject), and leaf nodes of the base tree correspond to the knowledge points related to the multiple versions of teaching materials. Wherein the base tree further includes multiple levels of non-leaf nodes. The non-leaf nodes of the multiple levels can be set according to textbooks of various versions of the teaching materials, for example, the non-leaf nodes of each level can respectively correspond to the chapters and sections related to the teaching materials, or can respectively correspond to the chapters, sections, course types and the like related to the teaching materials. In one case, the base tree may exist in the form of a tree structure or a directory.

The aforementioned disciplines may include, for example, mathematics, language, english, biology, chemistry, and the like. The school paragraphs may include, for example, a primary school paragraph, a junior school paragraph, a high school paragraph, a college school paragraph, and so forth. Versions of the textbook can include, but are not limited to, human religion, suzu religion, and the like

When the knowledge points are labeled for the theme, the theme is marked to the leaf nodes (corresponding knowledge points) of the basic tree, and the corresponding relation between the theme and the knowledge points corresponding to the leaf nodes of the basic tree is obtained.

After the target error question of the target user is obtained, the teaching material used by the target user, called target teaching material, can be continuously determined, a target business tree corresponding to the target teaching material used by the target user is obtained, leaf nodes of the target business tree correspond to teaching material knowledge points in the target teaching material, and correspondingly, the target business tree is associated with teaching material knowledge points related to a subject to which the target teaching material belongs, a period to which the target teaching material belongs, and a version of the teaching material to which the target teaching material belongs.

In another case, the target teaching material used by the target user may be determined, and the target service tree corresponding to the target teaching material used by the target user is obtained, for example, the target service tree is obtained when the target user is online, and then the target title of the target user is obtained.

The target teaching material is one of the aforementioned teaching materials of various versions, that is, the teaching material knowledge points associated with the target business tree are a subset of the knowledge points associated with the base tree. Correspondingly, teaching material knowledge points matched with the error problem knowledge points in the leaf nodes of the target service tree can be determined as target knowledge points, so that the corresponding relation between the target error problems and the target knowledge points is established and stored. Therefore, in the process of recording the wrong questions, the corresponding relation between the wrong questions and the teaching material knowledge points related to the target business tree corresponding to the target teaching material (the teaching material used by the target user) is established, and convenience is brought to subsequent user learning for the consolidation of the wrong question knowledge points related to the target wrong questions.

The basic tree is used for representing the knowledge points of the teaching materials of various versions, the knowledge points of the teaching materials of various versions can be clearly and clearly represented, the overall logic relationship among the knowledge points of the teaching materials of various versions can be embodied, and the marking of the knowledge points of the subject is facilitated. And then, no matter which version of teaching material the user switches to, the association relationship between the obtained title and the business tree (related teaching material knowledge point) can be established based on the mapping relationship between the basic tree and the business tree of the teaching material of the corresponding version.

And stage two, when the target user has a learning requirement, triggering a service request related to the target service, responding to the learning request of the target user for the target error, acquiring a first corresponding relation between the pre-established error and the knowledge points, namely the corresponding relation between the pre-established error of the target user and the teaching material knowledge points related to the target service tree, and determining the target knowledge points corresponding to the target error based on the corresponding relation. And then, according to a second corresponding relation between the pre-established knowledge point and the learning content, determining the target learning content corresponding to the target knowledge point, and feeding back the target learning content to the target user so as to enable the target user to learn the target learning content. The target learning content may include a target knowledge point corresponding learning video and/or a knowledge point note and the like.

And then, in the learning process of the target user aiming at the target learning content corresponding to the target error, the target user can trigger a note supplementing request for supplementing the learning note of the target user at any time. Accordingly, in response to the note supplementing request, user note content labeled by the target user for the target learning content is obtained, and the user note content may include understanding content, augmentation content and/or content representing learning mastery degree of the target learning content by the target user.

And then, establishing and storing the corresponding relation between the note content of the user and the target knowledge point. In this way, when the target user reviews the target error (or the target knowledge point) again, the target user can review not only the target learning content but also the note content of the user.

In the process, in the learning process of the target learning content by the target user, the user note content labeled by the target user for the target learning content can be obtained, the user note content is the understanding content of the user for the target learning content and/or the content representing the learning mastery degree of the target learning content, and is the content which is more required by the user.

The method and the apparatus for acquiring the learning content of the error problem provided in this specification are described in detail below with reference to specific embodiments.

For the sake of clarity of layout, the following description is first made with respect to a wrong-question listing process, i.e., a process of constructing a correspondence relationship between a user wrong question and a knowledge point (i.e., the first correspondence relationship mentioned later). Then, the flow of acquiring the learning content of the wrong question is introduced.

As shown in fig. 2, a schematic diagram of the error entry process is provided. The process can be realized by a target program, and the target program can be used as a server of the online learning system or a client of the online learning system. The object program may be installed in an electronic device, which may be implemented by any apparatus, device, platform, cluster of devices, etc. having computing and processing capabilities. The error recording flow in this specification will be described below by taking the target program as a server as an example, and the execution flow when the target program is used as a client may be referred to as the execution flow when the target program is used as a server. As shown in fig. 2, the error entry process may include the following steps S210 to S230:

in step S210, a target error question is obtained, and a plurality of error question knowledge points are marked on the target error question in advance.

In one implementation, the target error question may be any question that the target user makes an error in the course of an in-class exercise or examination, or may be a question that the target user actively triggers and needs to be included (for example, a question that the target user thinks that the target user does not master or needs to master with emphasis). The multiple wrong-question knowledge points pre-marked on the target wrong question can be marked by a professional teacher team and are any knowledge points in knowledge points related to teaching materials of all versions. The target wrong question may include, for example, question stem information and corresponding standard answer information, and may further include analysis information corresponding to the standard answer information.

In an embodiment, in step S210, the method may specifically include: and receiving a wrong question receiving and recording request of a target user, wherein the target wrong question is included. In this implementation manner, the target user may actively trigger the wrong-question receiving and recording request for the question when there is a need for receiving and recording the question, that is, the server may send the wrong-question receiving and recording request to the server through the target client, and accordingly, the server receives the wrong-question receiving and recording request of the target user and takes the question carried by the wrong-question receiving and recording request as the target wrong question.

In another embodiment, in step S210, the method may specifically include: and in response to detecting that the answer result of the target user for the target title is incorrect, determining the target title as a target error title. In the implementation mode, the target user answers the target question through the target client, after the answer is completed, a request for detecting the accuracy of the answer result of the target title can be triggered through the target client, and the server can respond to the fact that the answer result of the target user for the target title is incorrect when detecting that the answer result of the target title is incorrect, and determine the target question as the target wrong question. Specifically, in one case, in response to detecting that the answer result of the target user for the target title is incorrect, the server may feed back a prompt message to the target user (i.e., send the prompt message to the target client) to consult whether the target user needs to record the target title, and if the target user selects to record the target title, the server determines the target title as a target error in response to a request of the target user for recording the target title.

After the server obtains the target error question, in step S220, a target service tree corresponding to the target teaching material used by the target user is obtained, and the leaf nodes of the target service tree correspond to the teaching material knowledge points in the target teaching material. In one implementation, the target business tree may exist in the form of a tree structure or a directory. The target business tree may further include non-leaf nodes of a plurality of levels, which may, for example, respectively correspond to chapters and sections of the target textbook; for example, the lesson types may correspond to lessons, sections, lesson types, and lesson names of the target teaching materials. Specifically, the structural diagrams of the target service tree may be respectively shown in fig. 3A and 3B, the target service tree may exist in a tree structure as shown in fig. 3A, and the target service tree may exist in a directory as shown in fig. 3B.

In an embodiment, in step S220, the method may specifically include: and determining the target service tree according to the user information of the target user, wherein the user information comprises teaching material information of the target teaching material. In an implementation manner, the user information may be information preset by the target user, where the information may at least include teaching material information of the target teaching material, and correspondingly, the server may determine the corresponding target service tree according to the user information of the target user. In one implementation, the textbook information may include, but is not limited to, subject information, period information, and textbook version information. The term information may include, but is not limited to, the first term of the first grade of the primary school, the second term of the first grade of the primary school, the first term of the second grade of the junior middle school, the first term of the third grade of the senior middle school, etc. The textbook version information may include, but is not limited to, human religions (e.g., old human religions, new human religions), suzuki religions, and the like. It can be understood that the subject to which the target error question belongs, the corresponding school term and the corresponding teaching material version correspond to the teaching material information.

After the server acquires the target error question and the target service tree, in step S230, determining teaching material knowledge points matched with the error question knowledge points in leaf nodes of the target service tree as target knowledge points; and establishing and storing the corresponding relation between the target error question and the target knowledge point. That is, in this step, the teaching material knowledge points matching the wrong question knowledge points in the teaching material knowledge points corresponding to the leaf nodes of the target service tree are determined as target knowledge points, and the corresponding relationship between the target wrong question and the teaching material knowledge points of the target service tree is constructed and stored.

In one embodiment, it is considered that the versions of the teaching materials used in different regions are different, the knowledge points related to the teaching materials in different versions are different, and the diversity of the online topics, namely the topics, are respectively subordinate to the teaching materials in different versions (i.e. the knowledge points related to the teaching materials in different versions are subordinate to the teaching materials in different versions). The knowledge points of the questions are conveniently and quickly marked, the accuracy and the universality of the marked knowledge points are guaranteed, and when the professional teacher team marks the knowledge points for any questions existing on the line, the knowledge points are marked for the questions based on the knowledge points related to all versions of teaching materials, so that the requirements of users of different versions of teaching materials are met.

In one case, for better clarity of representing knowledge points of teaching materials of different versions and representing the overall logical relationship among the knowledge points of the teaching materials of different versions, a base tree can be constructed in advance for each subject (or each section of each subject), and the leaf nodes of the base tree corresponding to each subject (or each section of each subject) correspond to the knowledge points related to various teaching materials of the subject (or related to a certain section of the subject). When annotating knowledge points to the topic targets, the topic can be marked to the leaf nodes (corresponding knowledge points) of the basic tree, that is, the corresponding relationship between the topic and the knowledge points corresponding to the leaf nodes of the basic tree is recorded, so as to ensure the accuracy and the universality of the knowledge points marked by the topic. Accordingly, in one embodiment, the target knowledge points of the target problem are labeled as corresponding to leaf nodes in the pre-established base tree.

It can be understood that the leaf nodes included in the base tree correspond to knowledge points related to various teaching materials of the subject and the teaching material section to which the target error question belongs, the leaf nodes included in the target service tree correspond to teaching material knowledge points of the target teaching material, correspondingly, the teaching material knowledge points corresponding to the leaf nodes of the target service tree are subsets of the knowledge points corresponding to the leaf nodes of the base tree, that is, the knowledge points corresponding to the leaf nodes of the base tree can respectively belong to knowledge points related to service trees corresponding to multiple versions, as shown in fig. 3C, and multiple service trees can be split from the base tree according to the period information (as shown in fig. 3C, the period information is higher by one) and the teaching material version information (as shown in fig. 3C, suzu teach a version is higher by one first book, and the old teach version is higher by one first book). The basic tree and the plurality of business trees split from the basic tree all have a mapping relation, and correspondingly, a mapping relation exists between the basic tree (and leaf nodes thereof) and the target business tree (and leaf nodes thereof).

Correspondingly, in step S230, the process of determining the teaching material knowledge points matched with the wrong-topic knowledge points in the leaf nodes of the target service tree as the target knowledge points may specifically include: mapping a plurality of leaf nodes of the basic tree to target leaf nodes in the target service tree according to the mapping relation between the basic tree and the target service tree; and determining the teaching material knowledge points corresponding to the target leaf nodes as target knowledge points. Therefore, the corresponding relation between the wrong question of the target user and the teaching material knowledge point corresponding to the leaf node of the target service tree is established, namely the first corresponding relation between the wrong question of the target user and the knowledge point is established.

In one implementation, the target business tree and the base tree may be the same or different in hierarchical structure. The hierarchical structure of the business tree corresponding to the teaching materials of each version can be set according to actual requirements.

It can be understood that the flow shown in fig. 2 is an exemplary flow provided by the embodiment of the present specification, and in one case, step S220 may be executed before step S210, for example, when a target user logs in (or is called to be online) an online learning system through a target client (that is, may use a service provided by a server), a target service tree corresponding to teaching material information of a target teaching material used by the target user is directly obtained, then after a target error of the target user is obtained, the pre-obtained target service tree is directly read, and then step S230 is executed.

Through the process, the corresponding relation between the error questions of the target user and the teaching material knowledge points of the target teaching material used by the target user is established. And then, by combining the corresponding relation between the pre-constructed knowledge point and the learning content, the learning content corresponding to the wrong exercise required by the target user can be provided for the target user, so that the target user can learn the learning content corresponding to the wrong exercise. Then, in the learning process of the target user aiming at the learning content corresponding to the wrong questions, the learning notes can be labeled according to the learning comprehension and the mastering degree of the target user aiming at the learning content corresponding to the wrong questions, so that more personalized and more user-required learning contents can be collected aiming at the wrong questions of the user, and convenience is brought to the wrong question review of subsequent users.

The following describes a flow of a method for acquiring the learning content of the wrong question provided in the embodiment of the present specification. The method for acquiring the learning content of the error can be realized by a target program. In the following, the flow of acquiring wrong learning content in the present specification will be described by taking the target program as a server of the online learning system as an example, and the flow of executing the target program when the target program is a client of the online learning system can be referred to as the flow of executing the target program when the target program is the server. As shown in fig. 4, the method includes the following steps S410-S420:

in step S410, in the learning process of the target learning content corresponding to the target error, the user note content labeled by the target user for the target learning content is obtained, and both the target error and the target learning content correspond to the target knowledge point.

It can be understood that when there is a need to review the target error, the target user may select the target error (e.g., click on the target error) at its target client. And then after detecting the click operation, the target client sends a learning request aiming at the target error to the server. The server responds to the learning request aiming at the target error question, and determines a target knowledge point corresponding to the target error question based on a first corresponding relation between the error question and the knowledge point established in advance (namely the corresponding relation between the error question of the target user and the teaching material knowledge point of the target teaching material used by the target user); and determining target learning content corresponding to the target knowledge point based on a second corresponding relation between the pre-established knowledge point and the learning content, so that the target user can learn the target learning content. The target learning content may include a learning video and/or a knowledge point note corresponding to the target learning content. The learning videos may include system course videos provided by an online learning system for a user to learn in class.

Then, in the learning process of the target user aiming at the target learning content, the target user can trigger a note supplementing request for supplementing the learning note of the target user at any time according to the learning condition of the target user. And the server side responds to the note supplementing request and acquires user note contents labeled by the target user for the target learning contents, wherein the user note contents can comprise understanding contents, expansion contents and/or contents representing the learning mastery degree of the target user for the target learning contents. Further, in step S410, a corresponding relationship between the user note content and the target knowledge point is established and stored.

In one implementation, after the corresponding relationship between the user note content and the target knowledge point is established and stored, all users needing to learn the question related to the target knowledge point in the online learning system can learn the user note content, and the sharing of the learning content can be realized. In another implementation, after the corresponding relationship between the user note content and the target knowledge point is established and stored, the corresponding relationship between the user note content and the target knowledge point may be stored for the target user, so that the user note content may be used as the personal note content of the target user.

In the process, in the learning process of the target learning content by the target user, the user note content labeled by the target user for the target learning content can be obtained, the user note content is the understanding content of the target learning content and/or the content representing the learning mastery degree of the target learning content by the user, and the content more required by the user can be obtained.

In one embodiment, the target learning content includes a learning video corresponding to the target knowledge point; as shown in fig. 5, the process of acquiring the learning content of the wrong question may include the following steps S510 to S540:

in step S510, in the learning process of the target user for the learning video, in response to a screenshot request of the target user for the learning video, a video screenshot corresponding to the screenshot request is obtained. Then, in step S520, the marked content of the target user marked for the video screenshot is obtained. Next, in step S530, the video screenshot and the marked content are classified into the user note content.

In the learning process of the learning video corresponding to the target knowledge point, if the requirement of supplementing the learning note exists, a screenshot request for screenshot of the learning video can be triggered. As shown in fig. 6A, a target client of a target user provides a schematic diagram of a learning video presentation interface for the user. As shown in fig. 6A, on the right side of the learning video display interface, a screenshot button (the first button on the right side) may be displayed, and the target user may click on the screenshot button during the learning process. Correspondingly, the target client detects the click operation aiming at the screenshot button, generates the screenshot request and further sends the screenshot request to the server. And the server responds to a screenshot request of the target user for the learning video, and obtains a video screenshot corresponding to the screenshot request.

In one implementation, after a target client detects a click operation for a screenshot key and generates the screenshot request, on one hand, the screenshot request is sent to a server; on the other hand, the playing of the learning video may be paused and a markup content input window may be presented to the target user. The target user can enter the markup content tagged for the video screenshot in the markup content entry window and click a save button. And then after the target client detects that the storage key is clicked, acquiring the marked content and sending the marked content to the server. Correspondingly, the server side obtains the marked content of the target user for the video screenshot, and puts the video screenshot and the marked content into the note content of the user. Thereafter, the server may notify the target client (or the target client may automatically trigger) to close the markup content input window and continue playing the learning video.

In one implementation, the markup content input window may exhibit a number of markup tags, such as "selection tags" shown in FIG. 6B, including: and (4) marking labels such as key points and unintelligibility for the target user to select to mark aiming at the video screenshot. From which the target user can select one or more tags for annotating the video shot. And the target client takes the label selected by the target user as the marked content marked for the video screenshot. In another implementation, the marked content input window may show a content input area, and the target user may fill in his/her understanding content of the content shown in the video screenshot, etc. in the content input area to label the video screenshot. And the target client takes the comprehension content filled by the target user as the marked content marked for the video screenshot.

After the user note content is obtained, in step S540, the corresponding relationship between the user note content and the target knowledge point is established and stored. The specific implementation process of step S540 may refer to step S420, which is not described herein again.

In one implementation, a target user may also trigger a request for recording contents of understanding and/or representing knowledge point mastering conditions of the target user in a learning process for a knowledge point note corresponding to the target knowledge point, and a corresponding server may respond to the request to acquire labeled contents of the target user for the knowledge point note, and establish and store a corresponding relationship between the knowledge point note and the labeled contents thereof.

In another embodiment, as shown in fig. 5, the method for acquiring the learning content of the wrong question may further include the following steps:

in step S550, in the learning process of the target user for the learning video, if it is detected that the target user learns the designated node of the learning video, the content knowledge point of the system note content corresponding to the designated node is determined.

In step S560, the correspondence between the system note content and the target user is established and stored by mapping the content knowledge points to the target knowledge points.

In this implementation, for better improvement user's learning efficiency, promote its use and experience. At a designated node of the learning video, a professional teacher team will configure teacher notes, i.e., system note content. The note content of the system is key knowledge content summarized according to the content of the learning video. When the professional teacher team configures the note content of the system, the related knowledge points, namely content knowledge points, are marked on the note content of the system. In the learning process of the target user for the learning video, if it is detected that the target user learns the designated node of the learning video, the server can determine the content knowledge point of the system note content corresponding to the designated node, and establish and store the corresponding relationship between the system note content and the target user by mapping the content knowledge point to the target knowledge point. In this way, the target user can continue to learn the system note content while reviewing the target error later.

The acquired user note content and the system note content can be associated to the knowledge point note corresponding to the target error, so that the target user can learn the user note content marked by the target user and the system note content when reviewing the target error later.

In another implementation, if it is detected that the target user learns a specified node of the learning video, the server may further send the system note content corresponding to the specified node to the target client, and the target client may display the system note content corresponding to the specified node in a pop-up window manner, as shown in fig. 6C. The system note content corresponding to the displayed designated node also displays a button for representing that learning can continue, such as a "remembered" button shown in fig. 6C. In order to ensure the learning quality of the target user, when the target client displays the system note content corresponding to the specified node in a pop-up window form, the playing of the learning video can be suspended. After the target client detects the click operation of the target user on the key (the 'remembered' key) representing that the learning can be continued, the learning video can be continuously played.

In another embodiment, considering that the target user may learn about the learning video multiple times, in step S560, the method may specifically include: judging whether the note content of the system is associated with a target user at present; and if the system note content is not associated with the target user, establishing and storing the corresponding relation between the system note content and the target user by mapping the content knowledge points to the target knowledge points.

In the implementation mode, after the system note content is judged not to be associated with the target user currently, the corresponding relation between the system note content and the target user is established and stored by mapping the content knowledge points to the target knowledge points, so that repeated storage of the system note content can be avoided, and data redundancy is avoided.

In an embodiment, the method for acquiring the wrong-question learning content provided in the embodiment of the present specification further provides a function for the user to upload new wrong-question solution thought content, so as to record a new thought of the user and facilitate subsequent viewing of the new thought. In one case, the new solution thought content of the wrong questions uploaded by the user can be shared by other users, so that a new learning thought is provided for other users, and the learning efficiency of each user is improved. Correspondingly, the method may further comprise: responding to a content supplement request of a target user for a target wrong question, and acquiring solution thought content supplemented by the target user; and establishing and storing the corresponding relation between the content of the solution thought and the target wrong question.

In the implementation mode, when a new solution thought is provided for the target error problem for the target user, the solution thought content for the target error problem can be uploaded. Specifically, when detecting the solution thought content uploaded by the target user for the target error, the target client can send a content supplement request for the target error to the server, and the server responds to the content supplement request to obtain the solution thought content supplemented by the target user; and establishing and storing the corresponding relation between the content of the solution thought and the target wrong question.

In one case, when learning the target wrong question, other users can also learn the content of the solution thought supplemented by the target user, so as to improve the learning efficiency of each user.
