专利质量的事前测量揭示了引文网络增长的内在适应性
Ex-ante measure of patent quality reveals intrinsic fitness for citation-network growth
摘要：
我们已经构建了一个适应度参数，表征专利被引用的内在吸引力，从专利被授予时已知的相关发明的属性。这种外源获得的健身被证明是确定的时间增长的引文网络的优先附件和过时引起的老化，而不参考个别专利的特点运作的机制。我们的研究打开了一扇窗户，可以定量地理解富人变得更富有和适合变得更富有范式的相互作用，这些范式被建议用于管理现实世界复杂网络的增长动力学。
英文摘要：
We have constructed a fitness parameter, characterizing the intrinsic attractiveness for patents to be cited, from attributes of the associated inventions known at the time a patent is granted. This exogenously obtained fitness is shown to determine the temporal growth of the citation network in conjunction with mechanisms of preferential attachment and obsolescence-induced ageing that operate without reference to characteristics of individual patents. Our study opens a window on understanding quantitatively the interplay of the rich-gets-richer and fit-gets-richer paradigms that have been suggested to govern the growth dynamics of real-world complex networks.
