对新兴技术趋势的认识。美国专利引文网络引文的类别选择性研究

Recognition of Emerging Technology Trends. Class-selective study of citations in the U.S. Patent Citation Network

Péter Bruck, István Réthy, Judit Szente, Jan Tobochnik, Péter Érdi

摘要:

通过采用基于引用的专利递归排名方法,可以跟踪新技术领域的演变。具体而言,它表明,激光/喷墨打印机技术出现的重组两个现有的技术:顺序打印和静态图像生产。来自不同“先驱”类别的引文的动态阐明了新领域出现的机制,并提供了对未来技术发展进行预测的可能性。对于专利网络,PageRank阻尼因子的最佳值接近0.5; d=0.85的应用导致不可接受的排名结果。

英文摘要:

By adopting a citation-based recursive ranking method for patents the evolution of new fields of technology can be traced. Specifically, it is demonstrated that the laser / inkjet printer technology emerged from the recombination of two existing technologies: sequential printing and static image production. The dynamics of the citations coming from the different "precursor" classes illuminates the mechanism of the emergence of new fields and give the possibility to make predictions about future technological development. For the patent network the optimal value of the PageRank damping factor is close to 0.5; the application of d=0.85 leads to unacceptable ranking results.
