Embodiment

[0116] figure 1 It is a flow chart of the knowledge map visualization method in the embodiment of the present invention, such as figure 1 As shown, a knowledge map visualization method includes:

[0117] Step 101: Obtain the name of the knowledge to be queried.

[0118] Step 102: Use the SSH integration framework to query the triplet data corresponding to the knowledge name to be queried; the triplet data includes entities, entity categories and entity semantic relations.

[0119] Step 103: Convert triplet data into JSON format data.

[0120] Step 103 specifically includes:

[0121] Carry out entity semantic relationship analysis and entity analysis on the triple data respectively, and obtain the parsed entity semantic relationship and the parsed two entity names;

[0122] Determine the entity category to which the two resolved entity names belong according to the parsed entity semantic relationship, and obtain the category to which the entity belongs;

[0123] Store the ...

Abstract

The invention discloses a knowledge graph visualization method and system. The method comprises the following steps: querying triple data corresponding to a knowledge name to be queried by adopting anSSH integrated framework; converting the triple data into data in a JOSN format; determining parameter data of drawing elements according to the JOSN format data; acquiring equipment screen parameters, and determining initial coordinates of knowledge graph nodes in a drawing area according to the equipment screen parameters; optimizing the initial coordinates by adopting a response type force guiding layout algorithm to obtain optimized node coordinates; and carrying out Canvas drawing according to the optimized node coordinates and parameter data to generate a knowledge graph, and carrying out visual display on the knowledge graph. By the adoption of the method and system, the problem that a browser is incompatible due to the fact that a scalar graph is adopted can be solved, and the method and the system have the advantages of supporting multi-device screen display and supporting graph overall zooming and dragging.

Description

technical field [0001] The present invention relates to the technical field of knowledge graphs, in particular to a method and system for visualizing knowledge graphs. Background technique [0002] Knowledge graph (Knowledge Graph, KG) is to visually display knowledge and their interrelationships by means of visualization technology, in which entities serve as nodes in the graph, and semantic relationships between entities serve as edges of the graph. The knowledge map breaks data isolation, facilitates machine learning data and knowledge reasoning, thereby discovering deep knowledge and relationships, and providing support for smart search, intelligent question and answer, recommendation, and intelligent decision-making. [0003] At present, the knowledge map visualization technology uses css3 technology to control the layout and style of the scalar map nodes in the map in the web page. However, using a scalar graph as a node of the knowledge graph will lead to browser inc...
