微处理器中国专利发明主体合著关系分析

Research on Coauthoring Visualization of the Patent on Chinese Microprocessor Field

为发现微处理器中国专利发明主体的创新能力、主体间的合著模式、合著特点与规律,结合国内外合著分析方法研究状况,构建了发明主体合著关系可视化模型。该模型应用信息可视化技术挖掘隐含于专利数据库中的内在的、客观的、定量的信息,并以图形直观的呈现挖掘结果;同时,以科学计量学的合著率分析该领域科学合著程度。实证分析结果表明,我国的微处理器专利技术多集中在2000年以后,发明人合著强度大,申请机构与区域合著强度小,国内发明人创新能力低于国外发明人。

To discover innovation capability, coauthoring patterns and characteristics of innovation subject on？ Chinese microprocessor patent, in combination with related research status home and abroad, a visualization approach for coauthoring was proposed. The approach applied information visualization technique to extract the inherent, objective and quantitative information hiding in patent database, and showed mining result with chart. Coauthoring rate of bibliometrics was used to analyze cooperation intensity. The empirical illustration results show microprocessor patent applied by Chinese concentrated after 2000 mostly, inventor cooperation strength was high, assignee and region cooperation strength was low, innovation capability of inventor in home was lower than those at abroad.
