Abstract

The invention relates to a patent map visualization method and system. The patent map visualization method comprises the steps that multi-dimensional text vectors corresponding to patent literatures in a patent literature data set are obtained; clustering analysis is conducted on the multi-dimensional text vectors corresponding to the patent literatures to obtain multiple clustering results; multiple patent literatures corresponding to the clustering results are mapped to a two-dimensional plane so as to perform dimension reduction processing, and patent literature data points are obtained; visualized calculation is conducted on the multiple patent literature data points to generate visualized data, and the visualized data is displayed on the two-dimensional plane in a three-dimensional image mode. By the adoption of the patent map visualization method and system, the operation amount in the patent map generating process can be simplified, accordingly the occupation to a CPU and a memory is decreased, and real-time patent map generation and display are achieved.

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 ...
