Visualization Method of Patent Citation Analysis Based on Improved Hyperbolic Tree

Abstract

Citation analysis is an important content of patent analysis. Aimimg at the problems of visualizing the large hierarchical data in the limited display area, an improved hyperbolic tree for the visualization of patent citation analysis is proposed. The method combines the traditional hyperbolic tree with fisheye and other visualization technologies, and it can reveal the multi-level patent information, as well as display the overall layout and local details. Thus, the interaction between the overall and local data may be realized easily, and it is convenient for the users to understand the interested information.
