Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The knowledge graph is a graph formed by nodes and edges, and the nodes and the edges can be provided with characters to represent knowledge. "nodes" generally represent concepts and entities, and "edges" are generally used to represent relationship and attribute knowledge. An example of visualization of a small-scale knowledge graph is shown in fig. 1, and visualization of a large-scale knowledge graph is shown in fig. 2, where in fig. 2, circles represent vertices and lines represent edges.
The visualization of the knowledge graph aims to browse knowledge in the knowledge graph in an intuitive mode, find wrong knowledge and deduce entity relation and cause-effect relation. The main form of knowledge graph visualization is to display knowledge in the shape of a graph, and in terms of calculation cost, the solution of the reasonable layout calculation problem of nodes generally consumes larger calculation cost for a large-scale knowledge graph. When a user drags the knowledge-graph, trying to change the existing layout of the graph, the calculation amount caused by the re-layout calculation is huge. In terms of interaction convenience, the existing schemes for large-scale knowledge graph visualization mainly include the following:
and (3) a scheme based on sub-graph segmentation visualization: segmenting a complete large-scale knowledge graph into a plurality of sub-graphs; and respectively displaying a plurality of sub-graphs to realize browsing and interaction of the whole knowledge graph.
Visualization scheme based on multi-display stitching: in order to increase the display area of the display equipment, a plurality of displays are spliced, different parts of the knowledge graph are projected onto different displays, display and user interaction is achieved, and due to the fact that the positions of the first N-1 nodes need to be considered when the position of the Nth node is determined, the calculation amount during displaying of the knowledge graph each time is increased.
Visualization scheme based on attention mechanism: presume the user's attention; the attention-focused knowledge graph part is optimally displayed, specifically, the attention-focused knowledge graph part is displayed after being locally enlarged, and knowledge which is out of the attention range is processed in a hiding, fading, reducing and other processing modes.
The scheme based on sub-graph segmentation visualization and the visualization scheme based on multi-display splicing still adopt a mode of completely displaying all knowledge graphs, and essentially realize more convenient user browsing by increasing the display space. However, since the increase of the display space is limited, the scale increase of the knowledge map cannot be satisfied.
Visualization scheme based on attention mechanism: reducing the computational load displayed by the portion of the hidden knowledge graph that is not of interest; however, when a user needs to unfold a hidden partial atlas, a significant amount of layout display computation will still be incurred.
The problems in the prior art can be solved by the method in the first embodiment.

The image display device respectively displays at least one keyword node in a first direction of a display interface, and specifically, after hierarchically displaying at least one layer of sub-nodes corresponding to each keyword node in a second direction of the display interface by taking each keyword node as a reference: after the image display device displays the previous layer node and the next layer child node of the previous layer node, or after the image display node hierarchically displays any child node in at least one layer of child nodes and the next layer child node of any child node in at least one layer of child nodes on a display interface, or after the image display node hierarchically displays a second keyword node and a first child node on the display interface, or after the image display device displays at least one layer of child nodes at intervals along a second direction by taking each keyword node as a reference until at least one layer of child nodes are displayed, if the image display device receives a touch operation on a dragging cursor, the image display device can determine the current display content in the display interface, the moving direction of the dragging cursor and the moving distance of the dragging cursor; determining target display content according to the moving direction, the moving distance and the current display content; and displaying the target display content on the display interface.
For example, as shown in fig. 8, when the target node is any one of the at least one layer of sub-nodes, in a case where the image display apparatus receives a touch operation on the browse backspace key, the image display apparatus searches the knowledge graph for a previous layer node corresponding to the "lie four" node, that is, the "player" node, searches the knowledge graph for next layer sub-nodes of the "player" node as the "lie four" node and the "zhang three" node, and then the image display apparatus displays the "player" node, the "lie four" node and the "zhang three" node on the display interface.
In the embodiment of the application, when the image display device receives the touch operation on the dragging cursor, the image display device determines the current display content in the display interface, the moving direction of the dragging cursor and the moving distance of the dragging cursor; after the image display device determines the current display content, the moving direction of the dragging cursor and the moving distance of the dragging cursor in the display interface, the image display device determines the target display content according to the moving direction, the moving distance and the current display content; and after the image display device determines the target display content according to the moving direction, the moving distance and the current display content, the image display device displays the target display content on the display interface.
It should be noted that the moving direction is a direction parallel to or perpendicular to the first direction, specifically, the moving direction may be a horizontal direction on the display interface, may also be a vertical direction on the display interface, and may also be another direction on the display interface, which may be specifically determined according to an actual situation, and this is not limited in this embodiment of the application.
In the embodiment of the present application, in the case that the moving direction is a horizontal direction in the display interface, the moving direction may include a leftward direction and a rightward direction; in the case where the moving direction is a vertical direction in the display interface, the moving direction may include an upward direction and a downward direction.
For example, when the content displayed in the display interface of the image display device may be the content as shown in fig. 6, that is, the display interface includes a "player" node and an "actor" node, and the next-layer child nodes corresponding to the "player" node are a "zhangsan" node and a "lie-quan" node; the next-layer child nodes corresponding to the actor node are the wang five node and the zhao six node, when the image display device receives the touch operation on the dragging cursor, the image display device determines the moving direction and the moving distance of the dragging cursor, if the moving direction is upward movement and the moving distance is 90 pixel points, the image display device moves the display content in the display interface upward by 90 pixel points, so that the target display content shown in fig. 9 is obtained, and the target display content is the actor node, the wang five node and the zhao six node.
It can be understood that when the image display device finds at least one keyword node and at least one layer of sub-nodes in the knowledge graph according to the keywords, the image display device displays at least one keyword node in the first direction respectively, and hierarchically displays at least one layer of sub-nodes corresponding to each keyword node in the second direction of the display interface by taking each keyword node as a reference, so that when the image display device determines the position of the nth node, the position of the first N-1 nodes does not need to be considered, the calculation amount of the image display device when displaying the nodes in the display interface is reduced, and the speed of the image display device when displaying the nodes in the display interface is improved.
