基于专利引用耦合聚类的纳米领域新兴技术识别

Identification of Emerging Technologies in Nanotechnology Based on Citing Coupling Clustering of Patents

新兴技术识别是关系到一个国家和地区未来发展战略的重要议题。依据新兴技术和专利文献的核心特征,尝试建立了基于专利引用耦合聚类的新兴技术识别模型及其相关指标体系,并以美国专利商标局(以下简称美专局)授权专利数据库为数据源,对纳米技术领域展开了实证分析。结果证明,所构建的新兴技术识别模型具有较高程度的可行性和有效性,成功识别出了两项纳米新兴技术,其中一项主要与磁存储技术有关,另一项则与纳米粒子在给药系统和影像诊断等医药领域的应用有关。

Identification of emerging technologies is related to the national or regional development strategy. On the basis of citing coupling clustering of patents, this paper establishes an identification model of emerging technology and makes an empirical analysis in nano- technology using the patent data coming from USPTO （The United States Patent and Trademark Office） Patent Full-Text and Image Data- base. It is proved that this identification model of emerging technology is valid and identifies two emerging technologies in nanotechnology successfully. One of them is an emerging magnetic memory technology, the other is connected with the application of nanoparticles in drug delivery system and diagnostic imaging.
