S100A, determining at least one target child node with downstream nodes in the at least one child node or all child nodes.

S100B, displaying a corresponding expansion and retraction mark for each of the at least one target child node in the second area so as to expand or retract the corresponding downstream node.

The above steps S100A, S100B may be performed before step S101.

Fig. 1F schematically illustrates a schematic diagram of setting up deployment of a corresponding downstream node according to an embodiment of the present disclosure. As shown in fig. 1F, in the schematic diagram of fig. 1B, specific deployment and retraction identifiers (specifically, deployment identifiers) are added to some target sub-nodes to deploy their downstream nodes.

Fig. 1G schematically illustrates a schematic diagram of setting up deployment of a corresponding downstream node according to an embodiment of the present disclosure. As shown in fig. 1G, a specific deployment and retraction identifier (switched to a retraction identifier) is added to some target sub-nodes on the schematic diagram of fig. 1B to retract the deployed downstream nodes.

Optionally, the method further comprises: for each of the child nodes directly associated with the root node but not yet exposed within the second region, a corresponding deployment retract flag is exposed in the first region. This step may include being performed before step S101 described above.

Specifically, fig. 1H schematically illustrates a schematic diagram of one embodiment of the present disclosure showing a corresponding deployment and retraction identifier in the first area for each of the child nodes not yet shown in the second area. Fig. 1I schematically illustrates a schematic diagram of displaying a corresponding deployment and retraction identifier in the first area for each of the child nodes not yet displayed in the second area according to an embodiment of the present disclosure. As shown in fig. 1H and 1I, before being deployed, the deployment flag is specifically configured, and after being deployed, the deployment flag is switched to the stowage flag.

And S102, updating the display state of the knowledge graph in the webpage interface according to the type of the operation event and based on the target node.

Optionally, in this embodiment, updating, according to the type of the operation event and based on the target node, the display state of the knowledge graph in the web interface includes at least one of: in the case that the operation event is a first type of operation event, highlighting a penetrating relationship from a root node of the knowledge graph to the target node in the webpage interface; and displaying a downstream node of the target node in the webpage interface, wherein the downstream node and the target node are displayed in the webpage interface in a layered mode. Through highlighting the penetrating relation from the root node of the knowledge graph to the target node, a user can conveniently and visually and clearly know the concerned information, and the user experience is improved.

Fig. 1J schematically illustrates a schematic diagram of a first type of operation event causing a downstream node of the target node to be shown in the web interface according to an embodiment of the present disclosure. As shown in fig. 1J, the cursor hovers over a child node, which is the target node, which has downstream nodes, thereby exposing the downstream nodes of the target node in response to the cursor hover event.

Fig. 1K schematically shows a schematic diagram highlighting the penetration relationship according to an embodiment of the present disclosure. As shown in fig. 1K, specifically, the first type of operation event is, for example, a cursor hover event, where the cursor hover event is, for example: the cursor is suspended on a downstream node which is used as a target node, and a connecting line from the root node to the target node is thickened so as to highlight the penetrating relation.

Specifically, fig. 1L schematically illustrates a schematic diagram of performing hierarchical display based on the second type of operation event according to an embodiment of the present disclosure. As shown in fig. 1L, the second type of operation event is generated, for example, by clicking the expansion and retraction identifier, similarly to fig. 1J, a child node is used as a target node, and the expansion and retraction identifier of the target node is clicked, so that a downstream node of the target node is expanded, specifically, an area of the downstream node is a third area below the second area, thereby implementing the hierarchical display, and after the expansion, the expansion and retraction identifier is switched to the retraction identifier.

Specifically, the node downstream of the target node is collapsed by clicking the collapse flag in fig. 1L.

Here, although the second type of operation event and the third type of operation event are generated by taking the click expansion and contraction flag as an example in fig. 1L, the second type of operation event and the third type of operation event are not limited to be generated only based on the expansion and contraction flag, and actually, it is enough for those skilled in the art to make an adaptive configuration according to the requirements of the application scenario and the form of the knowledge graph.

In summary, the dynamic adjustment of the display nodes can be realized according to the operation events, or the display can be called as hierarchical display, so that the number of the displayed nodes is controllable, a user can conveniently and visually and clearly know the information concerned by the user, and the user experience is improved. In addition, all the nodes are not completely displayed at one time, so that the storage space of the webpage interface is saved, and the too slow rendering process is avoided.

Optionally, in a specific application scenario, for example, the application to the investment knowledge graph, the objects represented by the root node include: an enterprise or enterprise legal person or an enterprise actual controller; the objects represented by child nodes directly associated with the root node include: the object represented by the root node controls the enterprise that shares or participates in stock. The penetration relationship is highlighted as an investment relationship.

Further, optionally, the method further comprises: and zooming the displayed nodes of each level in the current knowledge graph while displaying the downstream nodes of the target node in the webpage interface.

Specifically, when downstream nodes of the target node are displayed in the web interface, and the number of displayed nodes is large, and the displayed nodes cannot be completely displayed, the displayed nodes in each level in the current knowledge graph are zoomed, so that the nodes in each level are completely displayed in the web interface.

Here, it should be noted that, in the above embodiments, the specific number of nodes and the number of regions shown in the knowledge graph are merely examples and are not limited. More nodes and regions can be shown in specific applications.

In this embodiment, when the node is displayed in step S102, a page element rendering operation may be performed according to entity data corresponding to the node to be displayed, so as to display the node in the web interface.

Specifically, the entity data includes entity relationship data, and entity attribute data; the entity relationship data is data representing the relationship between entities, and the entity attribute data is data representing the attribute of the entity. Illustratively, the entity relationship data and the entity attribute data are, for example, ternary arrays. For example, for the entity "belgium", the physical relationship data is (belgium-wife-melinda-gaitz), (belgium-president-microsoft), and the entity attribute data is (belgium-man-americans). Here, the entity relationship data and the entity attribute data are merely examples, which are determined specifically according to the description dimension of the entity.

Referring to the above operation of rendering page elements based on entity data to display nodes in a web interface, fig. 1M schematically illustrates a schematic diagram of implementing the above initialization based on entity data according to an embodiment of the present disclosure. As shown in fig. 1M, when hierarchically displaying through initialization in step S101, displaying a root node of the knowledge-graph in a first area of the web interface and displaying a child node directly associated with the root node in a second area of the web interface, includes:

s111, acquiring entity data forming the root node based on the ID of the root node.

For example, a lookup is performed from a pre-constructed fact expression library according to the root node ID to obtain corresponding entity data, where one entity data corresponds to one fact, and all the entity data form the fact expression library, and the fact expression library is, for example, a graph database because the entities involved in the knowledge graph and the relationships between the entities are complex.

S121, determining all child nodes or at least one node directly related to the root node and corresponding entity data according to the root node ID.

For example, in step S111, all child nodes or at least one node directly associated with the root node and corresponding entity data may be determined according to the entity data of the node based on the inter-node relationship description matrix.

In this embodiment, the relationship between the entities is visually recorded in the inter-node relationship description matrix, and for convenience of understanding, a simple example is given, for example, the first row and the first column of the inter-node relationship description matrix are respectively entity IDs, and according to a row-column crossing manner, if two entities have an association relationship, the matrix element where the entity ID located in the row direction and the entity ID located in the column direction cross in the row-column direction is 1, otherwise, is 0. Of course, this is merely an example and not a limitation.

Specifically, when determining the entity data of all the child nodes or at least one node directly associated with the root node, the relationship description matrix between the nodes may be specifically searched by using the entity ID in the entity data.

Since both the entity relationship data and the entity attribute data include the entity ID, the entity data used in the above steps may be the entity relationship data or the entity attribute data.

S131, performing page element rendering on the root node ID and entity data corresponding to all child nodes or at least one node directly associated with the root node, and displaying all child nodes or at least one child node in all child nodes directly associated with the root node in the second area of the webpage interface.

It can be seen that, due to initialization, the first area of the web interface shows the root node, and the second area shows all child nodes directly associated with the root node; or at least one child node in all child nodes directly associated with the root node is displayed in the second area of the web interface, so that the number of displayed nodes in the web interface is relatively limited, the display difficulty of the knowledge graph is reduced, in addition, the number of displayed nodes is controllable, and the interference caused to the user by other nodes which are not concerned by the user and displayed in the web interface is avoided, so that the user can be ensured to visually and clearly know the information concerned by the user, and the user experience is improved.
