[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first", "second", "target", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0033] Traditional knowledge graphs usually only involve single-dimensional data display and cannot comprehensively display multi-level and multi-dimensional teaching data such as courses, resources, knowledge points, problem points, and ability points. However, in the teaching field, there are complex association relationships between different teaching elements (such as courses, resources, knowledge points, etc.). Traditional knowledge graphs are difficult to effectively display this information, resulting in limited understanding and application of teaching content. In addition, traditional knowledge graphs are mostly displayed in static ways such as tree diagrams and matrix diagrams. This way has limitations in displaying complex data relationships and is not intuitive and dynamic enough. In addition, traditional 3D knowledge graphs are difficult to be integrated and displayed on the Web platform. Especially when dealing with a large amount of data and complex graphics, ensuring a smooth user experience is a challenge. Therefore, the embodiments of the present invention provide a knowledge graph display method to solve the above technical problems.

[0034] Embodiment 1

[0035] Figure 1 The figure is a flowchart of a knowledge graph display method provided in Embodiment 1 of the present invention. This embodiment is applicable to the interactive display scenario of a three-dimensional knowledge graph. This method can be executed by a knowledge graph display platform, which can be implemented in the form of hardware and / or software.

[0036] As Figure 1 shown, the method includes:

[0037] S101. In response to a trigger operation on a target knowledge graph, present a display page of the target knowledge graph. The display page includes at least a knowledge graph display area, an element display area, and a detailed introduction area. The target knowledge graph is a three-dimensional knowledge graph.

[0038] In this embodiment, the target knowledge graph can be understood as the knowledge graph corresponding to the item when the knowledge graph trigger control is triggered. In this embodiment, taking the teaching scenario as an example, the item corresponds to a course. It can be understood that this embodiment does not limit the type of the item and the application scenario of the knowledge graph display method. Figure 2 The figure is an example diagram related to the trigger of the target knowledge graph provided in Embodiment 1 of the present invention. As Figure 2 shown, taking the teaching scenario as an example, a large number of knowledge graphs of courses are deployed on the web front end. These knowledge graphs are integrated in the course management page. The front end presents the course management page, and the course management page includes a course management table. For each course in the course management table, there are corresponding management controls (view details, delete, take off the shelf, etc.) and a knowledge graph trigger control as shown by the red frame in Figure 2 . If the knowledge graph trigger control of a certain course is triggered, then determine that this knowledge graph is the target knowledge graph.

[0039] The display page can be understood as the page that the web front end jumps to after the knowledge graph trigger control corresponding to the target knowledge graph is triggered. The display page includes at least a knowledge graph display area, an element display area, and a detailed introduction area. The knowledge graph display area can be understood as the area for presenting a three-dimensional knowledge graph (3D multi-dimensional knowledge graph), the element display area can be understood as the area for presenting the elements corresponding to the knowledge graph, and the detailed introduction area can be understood as the area for presenting the detailed introduction of the knowledge graph and its corresponding elements.

[0040] Figure 3 The figure is an example diagram of a display page provided in Embodiment 1 of the present invention. As Figure 3As shown, the upper area 1 is the knowledge graph display area, presenting the 3D target knowledge graph. The target knowledge graph contains several levels (stereoscopic sections). The stereoscopic sections cut the three-dimensional space into different areas to accommodate different levels and different-dimensional instances. Each level has its corresponding instances, and the instances are presented in the form of spheres. Each instance has its corresponding elements, and the elements are presented in the form of labels on the target knowledge graph. That is to say, each instance on the knowledge graph display area has its corresponding label; each level of instances is presented in a corresponding color, and the colors of instances in different levels are different. The instances are connected based on the association relationship, and the connection methods include intra-level connection and cross-level connection. That is to say, every two instances with an association relationship are connected by a line, effectively reflecting the association relationship between the instances corresponding to the project. It can be understood that instances in the same level can be connected when there is an association relationship, and instances in different levels can also be cross-connected when there is an association relationship. The lower left area 2 is the element display area, and each element has its corresponding instance on the target knowledge graph. The elements are presented in the form of labels on the target knowledge graph. The lower right area 3 is the detailed introduction area. When a certain instance or element is selected, this area presents the introduction information of the corresponding instance / element. It can be understood that the sphere colors of the instances in the knowledge graph display area are the same as the colors of their corresponding elements in the element display area, effectively distinguishing the instance types, such as Figure 3 As shown, the instance corresponding to the problem point 2 is a yellow sphere, and the corresponding element is a yellow element.

[0041] Taking the teaching scenario as an example, the target knowledge graph includes at least a resource layer, a knowledge layer, a problem layer, and an ability layer; the resource layer, the knowledge layer, the problem layer, and the ability layer are all three-dimensional cross-sections, and the corresponding instances on each layer are also three-dimensional sphere instances. Among them, the resource layer corresponds to the course-related resource files, such as videos and PDF documents. The resource layer includes at least one resource instance. The resource instance can be any one or several of videos, audios, images, and PDF documents. It can be understood that the resource instances with an association relationship can be connected; the knowledge layer corresponds to the course-related knowledge points, that is, the key points of the course. Each course key point is a knowledge point instance. The knowledge layer includes at least one knowledge point instance. The knowledge point instances with an association relationship can be connected, and the knowledge point instance can also be connected to the corresponding resource instance based on the association relationship; the problem layer corresponds to the course-related problem points, that is, the weak points. Each course weak point is a problem point instance. The problem layer includes at least one problem point instance. The problem point instances with an association relationship can be connected. Each problem point instance can also be connected to the corresponding knowledge point instance based on the association relationship, and can also be connected to the corresponding resource instance based on the association relationship; the ability layer corresponds to the course-related ability points, that is, the abilities that can be mastered by learning the course. Each ability point is an ability point instance. The ability layer includes at least one ability point instance. The ability point instances with an association relationship can be connected. Each ability point instance can also be connected to the corresponding problem point instance based on the association relationship, can also be connected to the corresponding knowledge point instance based on the association relationship, and can also be connected to the corresponding resource instance based on the association relationship.

[0042] Specifically, in response to the triggering operation of the knowledge graph trigger control corresponding to the target knowledge graph on the course management page, a display page of the target knowledge graph is presented, and the three-dimensional target knowledge graph. Each element corresponding to the target knowledge graph and the detailed introduction information corresponding to the target knowledge graph are visually presented on the web front end.

[0043] S102. In response to the triggering operation on the target instance in the knowledge graph display area, present the target element corresponding to the target instance as a selected state in the element display area, and present the introduction information corresponding to the target instance in the detailed introduction area.

[0044] In this embodiment, the target instance can be understood as the selected instance. The target element can be understood as the element corresponding to the target instance, that is, the label of the target instance. The target element is located in the element display area, and the sphere color of the target instance is the same as the color of the target element. The introduction information can be understood as the detailed introduction of the target instance / target element. For example, if the target instance is knowledge point 1, the detailed introduction area presents the detailed introduction of knowledge point 1. The introduction information includes at least the name, type, label, and description of the instance.

[0045] Specifically, when the user clicks on a certain instance in the knowledge graph display area, this instance is the target instance. Figure 4 It is an example diagram of the display page when the target instance is selected provided in the first embodiment of the present invention, as Figure 4 shown. The target instance is problem point 3. In response to the trigger operation for the target instance (1), corresponding special effect transformations are performed on the three-dimensional target knowledge graph in the knowledge graph display area (for example, the sphere turns red, the instances having a connection relationship with the target instance are highlighted, the connection lines are highlighted, and other instances and connection lines are dimmed), and the target element (2) corresponding to the target instance is presented in a selected state in the element display area (as Figure 4 shown by deepening the background color of the element), and the introduction information (3) corresponding to the target instance is presented in the detailed introduction area.

[0046] S103. In response to the trigger operation for the target element in the element display area, the target instance corresponding to the target element is presented in a selected state in the knowledge graph display area, and the introduction information corresponding to the target element is presented in the detailed introduction area.

[0047] This embodiment corresponds to the presentation in step S102. Step S102 is the presentation effect when the target instance is triggered, and this step is the presentation effect when the target element is triggered.

[0048] In this embodiment, the target element can be understood as the selected element. The target instance can be understood as the instance corresponding to the target element. The target element is located in the element display area, and the sphere color of the target instance is the same as the color of the target element. The introduction information can be understood as the detailed introduction of the target element / target instance. For example, if the target element is problem point 3, then the detailed introduction area presents the detailed introduction of problem point 3.

[0049] Specifically, when the user clicks on a certain element in the element display area, this element is the target element. In response to the trigger operation for the target element, the target element is presented in a selected state (for example, by deepening the background color of the element), the target instance corresponding to the target element in the target knowledge graph in the knowledge graph display area is presented in a selected state, and corresponding special effect transformations are performed (for example, the sphere turns red, the instances having a connection relationship with the target instance are highlighted, the connection lines are highlighted, and other instances and connection lines are dimmed), and the introduction information corresponding to the target element is presented in the detailed introduction area.

[0050] It can be understood that since the target element is associated with the target instance and actually corresponds to the same business, the introduction information corresponding to the target element is the same as the introduction information corresponding to the target instance.

[0051] Optionally, as the first alternative embodiment of this embodiment, the method further includes:

[0052] a1. In response to a roaming operation on the target knowledge graph, change the display perspective of the target knowledge graph. The roaming operation includes mouse movement and shortcut key triggering. The perspective movement directions corresponding to shortcut key triggering include up, down, left, right, forward, and backward.

[0053] In this embodiment, Figure 5 is an example diagram of the auxiliary control on the knowledge graph display area provided in the first embodiment of the present invention. As Figure 5 shown, a reset control and a roaming control are sequentially arranged from top to bottom in the upper right corner of the knowledge graph display area. When the mouse moves to the roaming control, roaming rules are presented on the left side of the roaming control, including a mouse movement rule and a shortcut key triggering rule. The shortcut key triggering rule is: shift + W / A / S / D / Q / E to translate the model, and the mouse movement rule is: left button + mouse movement to adjust the model perspective. Here, W, A, S, D, Q, and E can respectively correspond to up, down, left, right, forward, and backward, or other corresponding relationships. This embodiment does not limit this. Based on the roaming rules, the user can move the display perspective of the target knowledge graph on the knowledge graph display area, achieving a 360° panoramic view switching and a display effect of zooming in and out on the far and near views, enabling the user to view the 3D target knowledge graph comprehensively without omission and more intuitively and dynamically understand the connections between different instances (teaching elements). Figure 6 is an example diagram of the knowledge graph display area based on the roaming operation provided in the first embodiment of the present invention. As Figure 6 shown, in response to the user's roaming operation, the position of the target knowledge graph in the knowledge graph display area has moved to the right side of the area, and there are also changes in the display angle of the target knowledge graph, the direction facing the interface, etc.

[0054] b1. In response to the triggering operation of the reset control on the knowledge graph display area, reset the target knowledge graph to its initial state.

[0055] In this embodiment, the initial state can be understood as the state presented on the knowledge graph display area when the target knowledge graph is first triggered to enter the display page, including at least the initial perspective and the initial selection state. The initial perspective is set based on the actual situation. For example, it can be the front view as Figure 3 shown, and the initial selection state is empty, that is, a state where no instance is selected. Similarly, as Figure 3 shown, each instance is presented in its corresponding color at its own level. The setting of the reset control is used to quickly switch back to the initial loading state after roaming or querying the knowledge graph.

[0056] Specifically, after the target knowledge graph on the knowledge graph display area may go through step a1, there are changes in both the display perspective and the selection state in the web front end. As Figure 6As shown, at this time, in response to the triggering operation of the reset control at the upper right corner of the knowledge graph display area, the target knowledge graph is reset to the initial state as shown in Figure 3 The initial state, the perspective of the target knowledge graph is restored to the front view perspective, and all instances and connections on the target knowledge graph are restored to the initial color, that is, the unselected state.

[0057] A method for displaying a knowledge graph provided by an embodiment of the present invention includes presenting a display page of a target knowledge graph in response to a triggering operation of the target knowledge graph. The display page at least includes a knowledge graph display area, an element display area, and a detailed introduction area. The target knowledge graph is a three-dimensional knowledge graph; in response to a triggering operation on a target instance in the knowledge graph display area, the target element corresponding to the target instance is presented in a selected state in the element display area, and the introduction information corresponding to the target instance is presented in the detailed introduction area; in response to a triggering operation on a target element in the element display area, the target instance corresponding to the target element is presented in a selected state in the knowledge graph display area, and the introduction information corresponding to the target element is presented in the detailed introduction area. The above technical solution can clearly reveal the connections between different teaching elements, effectively convey the changes in the sense of space or time sequence, enhance the user's understanding of the relevance of knowledge, and solve the problem of difficult effective display of multi-level and multi-dimensional teaching elements by integrating multi-dimensional teaching data such as courses, resources, knowledge points, problem points, and ability points and their correlation relationships, using three-dimensional space and cutting out different regions through a three-dimensional section; adopting a 3D modeling method for display, supporting users to roam the knowledge graph, freely adjust and switch perspectives, and at the same time supporting users to click on the graph instances and dynamically display the instance information and other instances directly related to the clicked instance, helping users retrieve related knowledge points, providing an immersive interactive experience for users, and solving the problems of static display limitations and insufficient interactive experience; seamlessly integrating the 3D knowledge graph into the Web teaching platform and making it possible to provide a smooth 3D graph display on the Web platform through optimization techniques, solving the problem of integrated display of the 3D knowledge graph on the Web teaching platform.

[0058] As the second alternative embodiment of this embodiment, the development steps of the target knowledge graph include:

[0059] a2. Obtain environmental special effect parameters and the knowledge graph core algorithm, combine the environmental special effect parameters and the knowledge graph core algorithm, compile and package them into an interactive script in a set format, and mount the interactive script to the front end; the set format is used to make the interactive script run in the front-end web browser; among them, the knowledge graph core algorithm at least includes knowledge graph data, instance three-dimensional coordinates, hierarchical section reference positions, and instance sphere special effect sets.

[0060] The knowledge graph display platform includes a web project and a Unity project. The web project visually presents the target knowledge graph through the web front-end, provides an interaction page with users, and presents corresponding interaction effects. The Unity project is used to produce the interaction script of the target knowledge graph and deploy it to the web front-end through the web project. The web front-end receives the user's interaction operation and responds to the operation by calling the corresponding logic to present the corresponding interaction effect on the web page. The development steps of the target knowledge graph are completed in Unity.

[0061] In this embodiment, the environmental special effect parameters can be understood as the picture parameters when the target knowledge graph is presented on the web front-end, including at least environmental parameters (Camera) and art special effect parameters. The environmental parameters include camera parameters and canvas parameters. Among them, the camera parameters can be understood as the perspective information of the target knowledge graph facing the user, and the canvas parameters can be understood as the presentation effects of each area in the display page, especially the canvas width and canvas height of the knowledge graph display area. The art special effect parameters can be understood as the special effect presentation effect information related to art on the display page, that is, the art special effect parameters of the user interface (UserInterface, UI). The art special effect parameters include scene UI text, skybox background, special effect prefab, starry sky particle special effect, instance and connection material, material color map, lighting effect parameters, etc. Among them, the scene UI text is the label of the instance. The skybox background is the background information of the target knowledge graph. The material color map is the parameter for editing the instance and connection material effects, and is used to specifically fill the content of the instance and connection.

[0062] The core algorithm of the knowledge graph can be understood as the algorithm statements corresponding to the target knowledge graph. The execution process of the core algorithm includes: 1. Initialization, clearing the historical knowledge graph data; 2. Receiving the target knowledge graph data and assigning the target knowledge graph data to an instance. The target knowledge graph data can be understood as each instance in the target knowledge graph and its specific introduction information, and the target knowledge graph data is in JSON format; 3. Calculating the three-dimensional coordinates of the instance and creating an instance sphere according to the three-dimensional coordinates of the instance; 4. Assigning an instance sphere special effect set to the target knowledge graph so that the core algorithm of the knowledge graph can be directly matched with the environmental special effect parameters selected by the user. Among them, the instance sphere special effect set includes the material color, collision body and prefabricated special effects of each level sphere; 5. Creating a canvas instance label, setting the label position and style and defining that the label always faces the camera (that is, faces the user); 6. Creating a connection line between the instances with an associated relationship based on the target knowledge graph data; 7. Assigning a connection line material set to the target knowledge graph so that the core algorithm of the knowledge graph can be directly matched with the environmental special effect parameters selected by the user; 8. Obtaining the hierarchical section reference position and creating a hierarchical section; 9. Obtaining the section material set and creating a section label. Among them, the section material set is similar to the connection line material set and is also used to enable the core algorithm of the knowledge graph to be directly matched with the environmental special effect parameters selected by the user. It can be understood that the above process steps in the core algorithm of the knowledge graph can be changed in the execution order and combined for processing based on the actual situation.

[0063] Specifically, in response to the user's selection of the environmental special effect parameters on unity and the acquisition of the core algorithm of the knowledge graph, the environmental special effect parameters are matched with the core algorithm of the knowledge graph and compiled into an interactive script in a set format. Among them, the set format is the format using the Web Graphics Library (WebGL) technology, so as to facilitate the operation of the interactive script in the front-end web browser. It can be understood that the interactive script integrates all the content related to the target knowledge graph in the unity project, at least including algorithms, scenes and resources. Deploying the interactive script to the web front-end provides a basis for the subsequent display of the target knowledge graph.

[0064] It can be understood that when the front-end responds to the user's trigger operation on the target knowledge graph subsequently, the interaction of the target knowledge graph is realized through the communication between unity and the web.

[0065] Embodiment 2

[0066] Figure 7The flowchart shows a method for presenting a knowledge graph according to the second embodiment of the present invention. This embodiment further optimizes any of the above embodiments and is applicable to the interactive presentation of a three-dimensional knowledge graph. This method can be executed by a knowledge graph presentation platform, which can be implemented in the form of hardware and / or software.

[0067] As Figure 7 shown, the method includes:

[0068] S201. In response to a trigger operation on the target knowledge graph, present a display page of the target knowledge graph.

[0069] It can be understood that, in response to a trigger operation on the target knowledge graph, the web front-end interacts with the unity project through the web project. The web front-end page loads the target knowledge graph; the web page adapts to the unity 3D knowledge graph area; unityWebGL is initialized, and a progress bar is used to provide progress feedback to the user. The Canvas displays the 3D target knowledge graph full-screen, and sends a loading success message to the web front-end.

[0070] S202. In response to a trigger operation on the target instance in the knowledge graph display area, change the target instance to a target color, highlight the associated instances connected to the target instance and the connection lines between the target instance and the associated instances, and gray out the other instances on the target knowledge graph except the target instance and the associated instances.

[0071] In this embodiment, the target color can be understood as the color used to distinguish the selected target instance from other instances. The target color can be, for example, red, or other colors, and the target color is different from the color of the instance itself. The associated instance can be understood as an instance having an association relationship with the target instance, and the target instance and the associated instance are connected by a line based on the association relationship.

[0072] Specifically, the user clicks on an instance in the 3D target knowledge graph in the knowledge graph display area, determines the instance as the target instance. In response to the trigger operation of the target instance, change the target instance to a target color, highlight the associated instances connected to the target instance and the connection lines between the target instance and the associated instances, and gray out the other instances on the target knowledge graph except the target instance and the associated instances.

[0073] As Figure 4 shown, the target instance in the knowledge graph display area is the knowledge point 2 on the knowledge layer. Change the instance color of the knowledge point 2 to red, and determine several associated instances connected to the target instance. Figure 4The associated instances include problem points 2 and 3 in the problem layer, as well as the user manual and computer video 2 in the resource layer. Highlight these associated instances. Problem points 2 and 3 in the problem layer are highlighted in yellow, the user manual and computer video 2 in the resource layer are highlighted in blue, the connections between the target instance and these four associated instances are highlighted in red, all other instances in the target knowledge graph except the target instance and the associated instances are dimmed, and all other connections in the target knowledge graph except the connections between the target instance and the associated instances are dimmed.

[0074] S203. Present the target element corresponding to the target instance as a selected state in the element display area.

[0075] In this embodiment, the element display area includes elements corresponding to all instances on the target knowledge graph. Since there is a one-to-one correspondence between instances and elements, correspondingly, when the target instance is triggered and selected, the corresponding target element is also presented as a selected state.

[0076] As Figure 4 shown, if knowledge point 2 on the knowledge graph display area is selected as the target instance, then the element corresponding to the target instance, that is, knowledge point 2, as the target element, deepens the background color of the target element in the element display area to present the target element as a selected state.

[0077] S204. Present the introduction information corresponding to the target instance in the detailed introduction area.

[0078] S205. In response to the trigger operation on the target element in the element display area, present the target element as a selected state.

[0079] Specifically, when the user clicks on any element in the element display area, determine the element as the target element. In response to the trigger operation of the target element, present the target element as a selected state and deepen the background color of the target element. As Figure 4 shown by the selection effect of the target element knowledge point 2.

[0080] It can be understood that the element display area also has a search box. The user can search for the name of the desired element / instance in the search box. In response to the name input by the user, present the target instance corresponding to the name as a selected state in the knowledge graph display area and present the target element corresponding to the name as a selected state in the element display area.

[0081] S206. Change the target instance corresponding to the target element to a target color in the knowledge graph display area, highlight the associated instances connected to the target instance and the connection lines between the target instance and the associated instances, and dim all other instances on the target knowledge graph except the target instance and the associated instances.

[0082] In this embodiment, the element display area includes a plurality of elements, and each element has a one-to-one correspondence with an instance on the target knowledge graph. Correspondingly, when the target element is selected and triggered, the corresponding target instance on the target knowledge graph also presents a selected state. Therefore, in the knowledge graph display area, the target instance corresponding to the target element is changed to a target color, the associated instances connected to the target instance and the connection lines between the target instance and the associated instances are highlighted, and the other instances on the target knowledge graph except the target instance and the associated instances are grayed out.

[0083] It can be understood that whether the target element or the target instance is selected, the perspective presented by the target instance is facing the user. Therefore, when the target instance presents a selected effect, the presentation perspective of the target knowledge graph is automatically adjusted so that the user can directly see the target instance in the target knowledge graph without obstruction, avoiding the situation where the target instance is blocked by other instances and connection lines when the initial perspective is retained.

[0084] S207. Present the introduction information corresponding to the target element in the detailed introduction area.

[0085] It can be understood that a knowledge graph display method provided in this embodiment realizes two-way communication between unity and web.

[0086] In the case where the target instance is triggered by the user, the unity project responds to the user's click on the target instance, modifies all instance spheres to gray, modifies all connection lines to gray, sets the target instance sphere to red, traverses the associated relationship array of the target knowledge graph, and determines whether a certain instance sphere is associated with the target instance. If not, switches to the next instance sphere and retraverses the associated relationship array of the target knowledge graph to determine whether the instance sphere is associated with the target instance, and loops until all instance spheres are traversed. When it is determined that a certain instance sphere is associated with the target instance, the connection line between the instance sphere and the target instance sphere is set to red, and the instance sphere is set to be highlighted; after the unity project responds to the user's click on the target instance, the web project passes the identifier of the clicked instance sphere to the web front end, and the corresponding clicked instance on the web page becomes a selected state, and the detailed information of the instance is displayed. The unity project and the web project execute in parallel in response to the user's click on the target instance, realizing two-way communication between unity and web in the scenario where the target instance is clicked and triggered.

[0087] In the case where the target element is triggered by the user, the web project responds to the user clicking on the target element of the web page, changes the target instance corresponding to the target element to the selected state on the web page, and displays the element / instance details on the web page; after the web project responds to the user clicking on the target element of the web page, it passes the target element identifier to the unity project. The unity project receives the target element identifier, changes all instance spheres to gray, changes all connection lines to gray, sets the target instance sphere to red, traverses the associated relationship array of the target knowledge graph, and determines whether a certain instance sphere is associated with the target instance. If not, it switches to the next instance sphere and retraverses the associated relationship array of the target knowledge graph to determine whether the instance sphere is associated with the target instance. The loop iterates until all instance spheres are also traversed. When it is determined that a certain instance sphere is associated with the target instance, the connection line between the instance sphere and the target instance sphere is set to red, and the instance sphere is set to be highlighted. The web project and the unity project execute in parallel in response to the user clicking on the target element, realizing two-way communication between the web and the unity in the scenario where the target element is clicked and triggered.

[0088] In the case where the reset control is triggered, the web front-end responds to the trigger operation of the reset control and sends a notification to the unity. After receiving the notification, the unity respectively performs the operations of smooth reset according to the initial state and traversing the knowledge graph data (JSON data) of the target knowledge graph. After traversing the knowledge graph data, the colors of each instance sphere and connection line are restored to the initial state.

[0089] A method for displaying a knowledge graph provided by an embodiment of the present invention includes presenting a display page of a target knowledge graph in response to a trigger operation on the target knowledge graph; changing a target instance to a target color in response to a trigger operation on the target instance in the knowledge graph display area, highlighting the associated instances connected to the target instance and the connection lines between the target instance and the associated instances, and graying out other instances on the target knowledge graph except the target instance and the associated instances; presenting the target element corresponding to the target instance in a selected state in the element display area; presenting introduction information corresponding to the target instance in the detailed introduction area; presenting the target element in a selected state in response to a trigger operation on the target element in the element display area; changing the target instance corresponding to the target element to the target color in the knowledge graph display area, highlighting the associated instances connected to the target instance and the connection lines between the target instance and the associated instances, and graying out other instances on the target knowledge graph except the target instance and the associated instances; presenting introduction information corresponding to the target element in the detailed introduction area. The above technical solution can clearly reveal the connections between different teaching elements, effectively convey the changes in the sense of space or time sequence, enhance the user's understanding of the relevance of knowledge, and solve the problem of difficult effective display of multi-level and multi-dimensional teaching elements by integrating multi-dimensional teaching data such as courses, resources, knowledge points, problem points, and ability points and their associated relationships, using three-dimensional space and cutting out different regions through a three-dimensional section; adopting a 3D modeling method for display, supporting users to roam the knowledge graph, freely adjust and switch perspectives, and at the same time supporting users to click on the graph instances and dynamically display the instance information and other instances directly associated with the clicked instance, helping users retrieve associated knowledge points and providing an immersive interactive experience for users to solve the problems of static display limitations and insufficient interactive experience; seamlessly integrating the 3D knowledge graph into the Web teaching platform and enabling smooth 3D graph display on the Web platform through optimization technology to solve the problem of integrated display of the 3D knowledge graph on the Web teaching platform.
