A method for generating knowledge map mapping

Abstract

The invention discloses a knowledge map mapping generation method. The method comprises the steps that hierarchical relationship and association relationship attributes of knowledge serve as input parameters, and coordinates of the knowledge mapped to a two-dimensional plane map are obtained; a knowledge type attribute serves as an input parameter, a graph element parameter definition and fractal calculation are utilized, and geometric graph shapes of knowledge units mapped to a two-dimensional plane are generated; information quantity of the knowledge serves as an input parameter, the projected area ratio of the information quantity and the two-dimensional map area is calculated, the size of an outer boundary box of the knowledge units mapped to the two-dimensional map area is calculated through the area ratio, and the sizes of graphs in the knowledge units are controlled through a largest external rectangle algorithm; a knowledge map with a proper proportion is generated by taking the knowledge attributes and user preferences as input parameters. According to the knowledge map mapping generation method, information of the hierarchical relationship and the association relationship of the knowledge, the knowledge type and the knowledge information quantity is comprehensively considered, the spatial mapping method of the knowledge is established, and a foundation base map is established for cognition and display of subject knowledge and platform application based on the knowledge.

Description

technical field [0001] The invention belongs to the technical field of education informatization, and more specifically relates to a method for generating knowledge map mapping. Background technique [0002] With the advancement of educational cognition theory and the development of educational information technology, knowledge maps have attracted increasing attention. With the development of Internet +, there is an urgent need for an independent knowledge organization platform based on knowledge maps. The generation of knowledge maps Methods and display effects are the foundation and core of knowledge maps. At present, the research and application of knowledge maps in my country is still in its infancy, and many technologies simply absorb foreign existing knowledge maps and other expression and display methods. When conducting educational resource organization and in-depth application, it is found that the layering of graphic display is not clear, and resource aggregation ...

AI Technical Summary

Problems solved by technology

When conducting educational resource organization and in-depth application, it is found that the layering of graphic display is not clear, and resource aggregation is a bit messy. When using nodes and edges for knowledge expression, too much attention is paid to the relationship between knowledge, while ignoring the level of knowledge Sexuality, the amount of knowledge inherent in knowledge, and personality traits
