Abstract

The present invention relates to a patent map visualization method and system. The method includes: obtaining a multidimensional text vector corresponding to each patent document in a patent document data set; performing cluster analysis on the multidimensional text vector corresponding to each patent document to obtain multiple Clustering results; map multiple patent documents corresponding to each clustering result to a two-dimensional plane to perform dimension reduction processing and obtain patent document data points; perform visual calculations on multiple patent document data points to generate visualized data, and Display visualization data on a two-dimensional plane as a three-dimensional image. The patent map visualization method and system provided by the present invention can simplify the calculation amount in the process of generating the patent map, thereby reducing the CPU and memory overhead, and realizing real-time generation and display of the patent map.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a visualization method and system for a patent map. Background technique [0002] The patent map is composed of various graphic information related to patents. The patent map uses the statistical analysis method to carefully and finely analyze the patent technology information indicators and their combinations to make analytical and interpretable graphic information to reflect the intricate information contained in a large amount of patent data. [0003] On the patent map, a point represents a patent document, and the distance from a point to the center point represents the degree of technical correlation between the patent and the center point. The closer the distance, the higher the technical correlation. Through the patent map, we can judge the overall distribution of patented technology, technology hotspots, technology distribution of applicants, and changes of technology ...
