[目的/意义]技术研发的核心是人才。研发团队是各领域技术发展的重点关注对象,也是机构研发实力的重要体现。[方法/过程]以德温特创新索引(DII)专利文献为分析对象,明确发明人人名消歧规则,利用发明人共现聚类确定主要研发团队,然后以3D打印的数字光处理相关专利来进行人名消歧后研发团队识别的实证分析。[结果/结论]证明专利发明人人名消歧有利于发明人专利数量的准确分析。 [Purpose / Significance] The core of technology research and development is talent. R & D team is the focus of technical development in all areas of the object, but also an important manifestation of the strength of R & D institutions. [Method / Process] Taking the Derwent Innovation Index (DII) patent document as the analysis object, the disambiguating rules of inventors’ names are clarified, and the main R & D team is identified by inventor’s co-occurrence clustering. Then the related patents are dealt with digitally printed digital light To conduct empirical analysis of R & D team identification after name disambiguation. [Result / Conclusion] It is proved that the patent name disambiguation of the inventor is conducive to the accurate analysis of the inventor’s patent quantity.
