基于文本聚类的稀土萃取技术专利信息分析
Rare earth extraction technology patent information analysis based on text clustering
摘要
Abstract
The rare earth is one of the important strategic resources, while as one of the biggest rare earth resources countries, the further depth development of rare earth is restrained in China due to lacking of core patented technology. In order to analyze the evolution of the core patented technology of rare earth, and solve the problem of rare earth patented layout, lingo text clustering method is selected to analyze rare earth patent data sets. The changes in research topics and the migration of patent applications subject is explored, and the patent map is demonstrated through visualization. The results of this study can provide references for tracing rare earth extraction patent hotspot, and have great significance for enterprise patent information applications, technology research and development and intellectual property planning layout.关键词
