Embodiment 1

[0059] According to the present invention, an academic network visual presentation method based on inter-map jumping of nebula diagrams includes:

[0060] Step M1: Obtain the nodes and edges of a large number of academic networks from the database, the nodes are papers, and the edges are the citation relationships between papers;

[0061] Step M2: Set the color and size of the nodes and the color and size of the edges according to the nodes and edges of the academic network structure, and store the nodes, edges and corresponding attributes in the graph file;

[0062] Step M3: The graph file uses a multi-process parallel method to lay out the massive academic network, determine the position of the node in the two-dimensional space, and add the location information to the graph file;

[0063] Step M4: storing the content in the graph file in the database;

[0064] Step M5: Generate a nebula map in real time based on the data in the database, and complete the front-end visual pr...

Embodiment 2

[0106] Embodiment 2 is a modification of embodiment 1

[0107] Taking the academic network led by 47,310 high-impact papers with more than 1,000 citations in the entire academic field as an example, this embodiment provides a method and system for visually presenting a massive academic network based on jumping between Nebula graphs and graphs. Obtain paper IDs and titles from the database, as well as citation relationships, set node and edge attributes based on the network structure, use automatic layout tools to quickly layout nebula graphs, efficiently store massive nebula graph data, and jump between graphs Visual presentation of massive nebula maps; specifically, such as figure 1 shown, including the following steps:

[0108] Step S1: Obtain the nodes and edges of a large number of academic networks from the database, that is, related papers and their citation relationships;

[0109] Step S2: Set the color and size of the nodes and the color and size of the edges accordi...

Abstract

The invention provides an academic network visual presentation method and system based on jump between star cloud images, and the method comprises the steps: M1, obtaining the nodes and connection edges of an academic network from a database, enabling the nodes to be papers, and enabling the connection edges to be the reference relation between papers; M2, setting node colors and sizes and colorsand sizes of connecting edges according to the nodes and the connecting edges of the academic network, and storing the nodes, the connecting edges and corresponding attributes in a graph file; M3, laying out the academic network by the graph file in a multi-process parallel mode, determining the positions of the nodes in the two-dimensional space, and adding position information into the graph file; M4, storing the content in the graph file in a database; and M5, generating a star cloud graph in real time according to the data in the database, and finishing front-end visual presentation of theacademic network star cloud graph by using an inter-graph skip mode. According to the invention, visual presentation of massive academic networks guided by high-citation papers in the whole field canbe quickly completed, so that the knowledge structure is intuitive and visual.

Description

technical field [0001] The present invention relates to the field of data network technology, in particular, to a method and system for visually presenting massive academic networks, and more specifically, to a method and system for visually presenting academic networks based on jumping between Nebula graphs. Background technique [0002] With the continuous advancement of science and technology, the number of papers serving as knowledge carriers is increasing rapidly. In this process, many influential academic papers have been born. A high-impact paper is often cited by a large number of papers. Considering high-impact papers and papers citing this article as nodes in the network, and the citation relationship between them as edges in the network, we can obtain an academic network led by highly cited articles. If we use a force-guided algorithm such as ForceAtlas2 to lay out the network, and set the color and size of nodes and edges, we can get the nebula map of the academ...
