Currently, when analyzing brands, most of them adopt business-level data Charts (ECharts), the ECharts is a pure JavaScript chart library, can be smoothly run on Personal Computers (PCs) and mobile devices, is compatible with most of current browsers, and the bottom layer relies on a lightweight Canvas library ZRender, so as to provide an intuitive, vivid, interactive and highly personalized customized data visualization chart. However, in this way, only a single data relationship can be displayed, and an Application Programming Interface (API) is less exposed and a custom plug-in is less. The display of tens of millions of data volumes cannot be met when the relational graph is constructed. The layout mode is less, and the node events are less.
A knowledge graph (knowledgegraph) is a semantic network in which nodes represent entities or concepts and edges represent various semantic relationships between entities or concepts. By using a knowledge graph in a search engine, complex associated information can be better queried, and a user intention can be understood from a semantic level, so that the knowledge graph is widely applied to various fields such as information search, information recommendation and the like. When brand analysis is performed, the composition, efficacy, product form, pain point, scene and the like of each series of products (mainstream products and emerging products) of a plurality of mainstream brands need to be subjected to incidence relation analysis. This associative analysis can be demonstrated using a knowledge graph.
Based on the above research, the present example provides a method for displaying a class knowledge graph to improve the above problems.
The embodiment provides a method for displaying a class knowledge graph, which is applied to the electronic device 100 shown in fig. 1, and the electronic device 100 executes the method for displaying a class knowledge graph provided by the embodiment. In the embodiment, the electronic device 100 may be, but is not limited to, an electronic device 100 with a processing capability, such as a Personal Computer (PC), a notebook Computer, a Personal Digital Assistant (PDA), or a server.

For example, the components may be directly electrically connected to each other via one or more communication buses or signal lines. The class knowledge-map displaying apparatus 10 comprises at least one software function module which can be stored in the memory 20 in the form of software or Firmware (Firmware), and the processor 30 executes various function applications and data processing by running the software programs and modules stored in the memory 20.
The Memory 20 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.

In particular, the display unit 60 may display pages and video output to the user, and the content of the output may include text, graphics, video, and any combination thereof. Some of the output results are for some of the user interface objects. In this embodiment, the display unit 60 may be a liquid crystal display or a touch display. In the case of a touch display, the display can be a capacitive touch screen or a resistive touch screen, which supports single-point and multi-point touch operations. The support of single-point and multi-point touch operations means that the touch display can sense touch operations generated at one or more positions on the touch display and send the sensed touch operations to the processor for calculation and processing. In the present embodiment, specific examples of the display unit 60 include, but are not limited to, a liquid crystal display or a light emitting polymer display.
It is to be understood that the configuration shown in fig. 1 is merely exemplary, and that the electronic device 100 may include more or fewer components than shown in fig. 1, or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Based on the implementation architecture of the electronic device 100, please refer to fig. 2, fig. 2 is a flowchart illustrating the class knowledge graph display method provided in this embodiment, which is executed by the electronic device 100 shown in fig. 1, and the flowchart shown in fig. 2 is described in detail below.
Step S10: receiving a query request, acquiring a target type node from the class knowledge graph according to the query request, and determining a target entity node from entity nodes associated with the target type node.
Since the construction of the knowledge graph depends on data and the relationship between nodes in the knowledge graph needs to be established through data, in this embodiment, the class data is processed in advance based on the Jaccard similarity algorithm to accurately obtain the relationship between the ten-thousand class data, and the class knowledge graph is constructed based on the relationship between the class data, where the constructed class knowledge graph is stored in the electronic device 100.
In this embodiment, the constructed class knowledge graph includes a plurality of entity nodes and a plurality of type nodes, each entity node is associated with each type node, that is, each entity node is associated with a plurality of entity nodes, and each entity node is also associated with a type node to which other entity nodes associated with the entity node belong.
Optionally, in this embodiment, after the item data is processed, the constructed item class knowledge graph may include 7 types of type nodes, including seven types of nodes, namely, Product Form (Product Form), Product (Product), composition (Ingredient), Brand (branch), efficacy (Benefit), pain point (sense), and scene (Context), where each type of node includes multiple entity nodes.
As an alternative implementation manner, in this embodiment, the query request may be input by the user from an interactive interface provided by the electronic device 100, and the user may initiate a query operation from the interactive interface to initiate the query request to the electronic device. For example, the interactive interface provided by the electronic device 100 includes a query button, and the user can initiate a query request to the electronic device 100 by clicking the query button.
In this embodiment, the query request may further include an entity node to be queried, a user may input the entity node to be queried through an interactive interface provided by the electronic device 100, and initiate the query request to the electronic device 100, the electronic device 100 responds to an operation of the user, obtains a type node to which the entity node to be queried belongs according to the input query request, finds the entity node to be queried from the entity nodes included in the type node, and uses the entity node to be queried as a target entity node.
And after the target entity node and the type node to which the target entity node belongs are obtained, displaying the target entity node and the type node to which the target entity node belongs to an interaction interface, and waiting for the operation of a user.
Optionally, in order to facilitate the operation of the user, in this embodiment, for each entity node, when the entity node is displayed on the interaction interface, the associated type node of the entity node needs to be displayed, and the type node expanded by the entity node is another associated type node except the type node to which the entity node belongs. For example, the entity node is a late night, and belongs to a scenario (Context) type node, and the type nodes associated with the late night are six types of nodes, namely, a Product Form (Product Form), a Product (Product), a component (Ingredient), a Brand (branch), a efficacy (Benefit), and a pain point (pain), and when the nodes are displayed on the interface, the nodes are one entity node (late night) and six types of nodes (the other six types of nodes except the scenario), as shown in fig. 3.
Therefore, after the target entity node and the type node to which the target entity node belongs are determined, the other entity nodes associated with the target entity node and the type nodes to which the other entity nodes belong can be obtained, and further, the target entity node and the type nodes associated with the target entity node can be displayed on an interactive interface together, so that the operation of a user is facilitated.
As an optional implementation manner, in this embodiment, after receiving a query request input by a user, a graph object may be obtained in a componentDidMount, and a target entity node and a type node associated with the target entity node are determined.
Step S20: and responding to an operation event of a user on the first type node associated with the target entity node, and displaying all the first entity nodes associated with the first type node.
In this embodiment, there may be a plurality of type nodes associated with the target entity node, and the type node in which the operation event is performed is denoted as a first type node.
In an exemplary embodiment, after the target entity node and the type nodes associated with the target entity node are displayed on the interactive interface, the user selects one type node or multiple type nodes, and operates the selected type node, where the selected type node is the first type node, and the electronic device 100 detects and responds to an operation event of the user on the first type node to display the first entity node associated with each first type node.
Step S30: detecting whether there are at least two of the first entity nodes that are identical.
The electronic device 100 responds to an operation event of a user on the first type node, displays all first entity nodes associated with each first type node, and detects whether at least two first entity nodes identical to each other exist in all the first entity nodes. It is to be understood that the same at least two first entity nodes are respectively associated with, i.e. respectively belong to, different first type nodes.
In a further embodiment, step S31 is executed if it is detected that there are at least two first entity nodes that are the same, and step S32 is executed if it is detected that there are no at least two first entity nodes that are the same.
Step S31: and establishing a closed loop among the target entity node, the first type node and at least two same first entity nodes for displaying.
Step S32: responding to an operation event of a user on a second type node associated with each first entity node, showing all second entity nodes associated with the second type node, detecting whether the same first entity node and the second entity node exist or whether at least two second entity nodes exist or not until the same first entity node and the second entity node exist or at least two second entity nodes exist, establishing a closed loop among the target entity node, the first type node, the second type node and the same first entity node and the second entity node or establishing a closed loop among the target entity node, the first type node, the first entity node, the second type node and the same at least two second entity nodes, and (5) displaying.
If at least two first entity nodes which are the same exist, a closed loop among the target entity node, the first type node and the at least two first entity nodes which are the same is established, an interactive interface is returned, and the closed loop is displayed, as shown in fig. 4. It should be noted that, in practical applications, when a closed loop is established for displaying, two identical entity nodes are presented as one entity node when an interface is displayed, as indicated by arrows in fig. 4, two identical first entity nodes are presented as one first entity node when a closed loop is established.
If at least two first entity nodes which are the same do not exist, returning the type node associated with each first entity node to the interactive interface for displaying, as shown in fig. 5. After the type nodes associated with the first entity nodes are returned to the interactive interface, the type node selected by the user and subjected to the operation event is the second type node.
The electronic device 100 responds to an operation event of the user on the second type node, presents all second entity nodes associated with the second type node, and detects whether the same first entity node and second entity node exist or whether at least two second entity nodes which are the same exist.
If the same first entity node and the same second entity node exist, a target entity node, a first type node, a second type node, and a closed loop between the same first entity node and the same second entity node are established, and returned to the interactive interface for displaying, as shown in fig. 6. Or, if there are at least two second entity nodes that are the same, a closed loop between the target entity node, the first type node, the first entity node, the second type node, and the at least two second entity nodes that are the same is established, and the closed loop is returned to the interactive interface for display, as shown in fig. 7. Or, if the same at least two second entity nodes, the same first entity node and the same second entity node exist at the same time, the target entity node, the first type node, the second type node, and the closed loop between the same first entity node and the second entity node, and the closed loop between the target entity node, the first type node, the first entity node, the second type node, and the same at least two second entity nodes are established at the same time, and are returned to the interactive interface for displaying, as shown in fig. 8.

For example, if there are 10 physical nodes associated with a certain type of node and the number of displays is set to be 5, then when displaying the physical nodes associated with the type of node, only the first 5 physical nodes with the highest degree of association need to be displayed.
It should be noted that, in this embodiment, if the same entity node exists, it indicates that the entity node is the commonality of the upper layer entity node to which it is associated. For example, in fig. 9, if the target entity node is an overnight entity node, the associated first type node has six types of nodes, namely, Product Form (Product Form), Product (Product), Ingredient (Ingredient), Brand (Brand), efficacy (Benefit), and pain point (sense), wherein the first entity node associated with the Brand type node has Brand a, Brand B, Brand C, Brand D, and Brand E; the first entity node associated with the first type node Tension has symptoms a, symptoms b, symptoms c, symptoms d and symptoms e, wherein the second type node associated with the symptoms a entity node also has Brand, Product Form, Product, Context, Benefit and Ingredant, and the second entity node associated with the second type node Brand has brands A, F, G, H and I.

Step S322: and detecting whether the second click event exists in the second type node or not, and displaying all second entity nodes related to the second type node in which the second click event exists.
After the type nodes associated with the first entity node and the first entity node are displayed on the interactive interface, a clicking event of a user is detected and responded, and the type node clicked by the user is selected, wherein the type node clicked by the user is a second type node.
After the second type node is selected, whether a second click event exists in the selected second type node or not is detected, namely whether a double click event exists or not is detected, and all second entity nodes related to the second type node with the double click event exist are displayed.
As an optional implementation manner, in order to improve accuracy of data output, in this example, after a second click event exists in a selected first type node or a selected second type node, whether the first type node has an associated first entity node or whether the second type node has an associated second entity node is detected, and if so, all first entity nodes associated with the first type node are displayed or all second entity nodes associated with the second type node are displayed.

It can be understood that, before the presentation, whether the entity node has the associated type node or not may also be detected, and if so, the presentation is performed, so as to improve the accuracy of data output.
As an optional implementation manner, in this example, after the display is performed, the displayed entity node or type node may be further collected according to an operation event of the user. For example, after a certain entity node and a type node associated with the entity node are displayed on an interface, a user operates the entity node, and in response to an operation event for the entity node, the electronic device 100 packs the type node associated with the entity node, only displays the entity node, and does not display the type node associated with the entity node, and optionally, the operation event may be a single-click event or a double-click event.
