Fig. 2 schematically shows a flowchart of a method for integrating visualization based on GIS and knowledge-graph according to the present invention, and the method starts in step S210.
In step S210, entity and relationship data of the knowledge graph are obtained from the server. The entity and relation data of the knowledge graph obtained from the server side can be presented in a view mode through rendering, and rendering is used for presenting the entity and relation in the knowledge graph in the view mode, so that visualization is achieved.
Subsequently, in step S220, the entity and relationship data input by the server are rendered in the GIS map and then rendered in the knowledge graph.
The GIS view and the map view can be 2D views or 3D views.
The entity and the relationship data of the knowledge graph obtained from the server can be directly used for knowledge graph display, and in the embodiment of the invention, the entity and the relationship data of the knowledge graph obtained from the server can also be used for GIS map view display, and in order to realize GIS map display, the attribute of the entity of the knowledge graph at least comprises longitude and latitude fields. Preferably, each entity of the knowledge graph should also have a unique ID, so as to achieve a normal combined display on the graph view and the GIS map.
Subsequently, in step S230, switching is performed between the GIS view and the knowledge graph view according to an operation request of the user.
According to the embodiment of the invention, the display contents of the GIS view and the knowledge graph view are different, the GIS view can conveniently display the information of the geographic position, coordinates, time and the like of the entity, and the knowledge graph view is suitable for displaying the information of labels, attributes, attributions and the like.
The user can perform different operations on the entity by switching between the GIS view and the knowledge graph view, so that the requirements under different scenes are met.
Subsequently, in step S240, the operation result of the user is synchronized between the GIS view and the knowledge-graph view, and the data of the GIS view and the knowledge-graph view are subjected to a differential processing.
According to the embodiment of the invention, when a user operates one view, the other view also responds, namely the two views are synchronous, and the user can operate between the two views according to the requirement, wherein the data of the two views are automatically subjected to differential processing, so that the difference of the data attributes displayed by the two views is adapted.
Further, the entity and relation information between the GIS view and the knowledge graph view are common, and the difference is that the knowledge graph view can display labels, attributes and attribution information, the GIS view can display geographic position, coordinates, time and other information, and when a user switches between the GIS view and the knowledge graph view, the switched view can only extract the entity and relation information after the user operates and render the entity and relation information in the view.
Further, the user can query or expand and display the interface of the current GIS view or the knowledge graph view through the interactive interface, so that the respective advantages of the GIS view and the knowledge graph view can be fully utilized to expand and analyze. Taking a GIS view as an example, the method comprises two expansion forms of space expansion and geographic space expansion. The spatial distance expansion refers to expanding or inquiring the view content according to the spatial distance of the entity, for example, when a user switches from a knowledge map view to a GIS view, the three-dimensional GIS map view is adopted to display track information of a specified entity and entity distribution information in a track range according to time information, height information and preset range information included in expansion attributes supported by the GIS map view. In a real application scene, the map view has an aircraft carrier entity, and a user selects expansion according to a space distance, so that all relevant entities such as an aircraft and a guard ship within a certain range can be searched and displayed. If the expansion is performed in the GIS view, the aircraft and the guard ship are different from the ground level in height and working environment, so that the guard ship can fly at sea level while the aircraft flies at a certain height. This is an effect that cannot be seen in the atlas view, and is one of the differential view manifestations.
In the embodiment of the invention, when the GIS and the map view are not consistent in view expression, the GIS and the map view are judged to be incompatible, for example, the map view can be subjected to rich layout operation, and the GIS cannot be embodied; and GIS can show route and history track according to time, these map looks can't embody. When the GIS is incompatible with the map view, the basic entity and the relationship are expressed, and on the basis of meeting the basic entity and the relationship expression, upgrading display processing is performed, if a certain node of the map view is an airplane and has an attack range attribute, when the GIS is switched to the GIS view, the attack range of the entity can be automatically drawn, and the flight effect can be simulated. The video content can be flexibly upgraded and downgraded according to the intention of the user.
The embodiment of the invention also realizes the cross expansion function of two different views, and particularly can query or expand and display the GIS map view according to the map view information such as labels, attributes, attributions and the like; the map view can be queried or expanded and displayed according to the GIS view information such as time, geographic space, distance and the like, so that the user operation is simplified, and the frequent switching between the two views is avoided.
The embodiment of the invention also realizes that the user adds the entity in the GIS map by marking the coordinate points, and specifically comprises the following steps: receiving coordinate information marked by a user in a GIS map;
the coordinate information is packaged and then sent to a server, and a new entity is added by the server and written into a graph database;
and receiving entity information associated with the marks returned by the server.
The embodiment of the invention also provides an optimized GIS view rendering and displaying flow, which specifically comprises the following steps:
packaging rendering related parameters and then sending the parameters to a server;
receiving entity and relation data returned by a server in the form of stream data;
and loading rendering in the GIS map by using an asynchronous multithreading queue according to the entity and the relation data, and then rendering.
According to the embodiment of the invention, on one hand, the entity data in each of the GIS and map nodes is the same in the map database, but different view showing methods are different, and each side point is: the entities under different layout methods of the knowledge graph view are all located at different positions, but the GIS just emphasizes the connection of the geographic space information, and the entity positions are the effective information; on the other hand, the GIS view can be communicated with the knowledge graph view, so that the consistency of data is maintained. For example, a coordinate is marked in the GIS view as a new entity in the map database as a new behavior, so that the new entity can be visible in the GIS view and can be displayed without performing redundant operations when switching to the knowledge graph view. For another example, when a plurality of new entities are loaded in the expansion operation of the knowledge graph, and the knowledge graph is switched to the GIS view, the new entities loaded at the moment are displayed in the GIS view.
In a specific embodiment of the present invention, a method for analyzing visual data based on GIS and a knowledge graph is provided, including:
step 1: the user searches for an entity;
step 2: the client encapsulates the parameter optimization related resources and sends a request to the server;
step 3: the server receives the corresponding request and returns stream data;
step 4: the client receives the streaming data, loads rendering by using an asynchronous multithreading queue, realizes quick and smooth rendering of the server, and displays the rendering in the visual view;
step 5: the user selects the geographic space and the time as expansion conditions to expand one plane, and the result is displayed to a visual view after success;
step 6: switching to a GIS view, and seeing the entity and the relation in the knowledge graph and also seeing the history navigation line and the current position of the airplane;
step 7: expanding the space distance and the time of the airplane entity, wherein the difference distance between the space distance and the time of the current position of the airplane is added into the view within the searching range;
step 8: data analysis and mining are performed.
