共同发明人网络中的社区结构影响专利首次引用的时间

Community structure in co-inventor networks affects time to first citation for patents

W. Doonan, K. W. Higham, M. Governale, U. Zülicke

摘要:

我们研究了一组专利的共同发明人网络中的社区结构,并将这种结构与这些专利如何获得首次引用的动态联系起来。第一次引用的时间滞后的统计学显著差异与该引用是否来自其所列发明人与被引用专利的发明人在同一社区共享成员资格的专利有关。虽然不同的社区检测算法识别的发明人社区结构在几个方面不同,包括社区规模分布,第一次引用的时间差异的幅度是鲁棒性的展示。我们的工作是能够量化的预期加速知识流动的发明家社区,从而进一步建立网络分析工具的效用,研究创新动态。

英文摘要:

We have investigated community structure in the co-inventor network of a given cohort of patents and related this structure to the dynamics of how these patents acquire their first citation. A statistically significant difference in the time lag until first citation is linked to whether or not this citation comes from a patent whose listed inventors share membership in the same communities as the inventors of the cited patent. Although the inventor-community structures identified by different community-detection algorithms differ in several aspects, including the community-size distribution, the magnitude of the difference in time to first citation is robustly exhibited. Our work is able to quantify the expected acceleration of knowledge flow within inventor communities and thereby further establishes the utility of network-analysis tools for studying innovation dynamics.
