Embodiment 1

[0055] This embodiment discloses a method for realizing interactive navigation of knowledge map visualization, such as figure 1 ,include:

[0056] S100. Draw a synchronous dynamic navigation map in a preset navigator on the premise that the main map drawing method of the knowledge map has been written. Refer to the results of this step figure 2 .

[0057] In this embodiment, the specific method of S100 is:

[0058] S101. According to different display resolutions, dynamically obtain the size of the current main image window, and the window size reserved for the navigation map in the preset navigator;

[0059] S102. According to the obtained window size, respectively calculate the width and height scaling ratios when the main image is mapped to the navigator;

[0060] S103. Design a navigation map drawing method; in some preferred embodiments, the specific method of S103 is: on the basis of the main map drawing method, import the scaling ratio calculated in S102, and draw ...

Abstract

The invention discloses a method for realizing visual interactive navigation of a knowledge graph, which comprises the following steps of: drawing a synchronous dynamic navigation graph in a preset navigator on the premise that a knowledge graph main graph drawing method is compiled, adding a bush layer to the navigator to display the position and size of the current viewport of the main graph relative to the node area of the whole graph, mapping the current visual area of the main image to a navigator bush layer to realize corresponding size and position change of the navigator bush when themain image is moved, zoomed and dragged by a node, calculating the position of the main graph node area relative to the viewport according to the position of the bus in the navigator, correcting the navigator according to the layout form of the main map, and switching according to the layout form of the main map, and correcting the content of the navigator. According to the method, the size and position relation between the current viewport of the main image and the whole image is provided more visually, friendly and accurately, and the problem that a traditional thumbnail cannot reflect the dynamic change of the main image in real time is solved.

Description

technical field [0001] The present invention relates to the field of knowledge graph visualization, and in particular to a method for realizing interactive navigation of knowledge graph visualization. Background technique [0002] Knowledge Graph, known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of different graphics showing the knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining , analyze, construct, map and display knowledge and their interconnections. [0003] Because the knowledge map has the advantages of intuitiveness, comprehensiveness, clarity, and customization in data display, with the development of modern society, it has been more and more practically applied in various industries that need to organize and analyze a large amount of data. [0004] When using the knowledge graph to analyze more...
