One size doesn't fit all: on the co-evolution of national evaluation systems and social science publishing

Diana Hicks
2012 Confero: Essays on Education, Philosophy and Politics  
At the same time, governments have accepted the argument that a one size fits all research evaluation system is unfair, and research evaluation protocols have been revised to better suit social science  ...  All but one of the SSCI cited documents were in English; all the PSCI cited documents were in Polish.  ...

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

William Doonan, Kyle W. Higham, Michele Governale, Ulrich Zülicke
2019 Applied Network Science  
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  ...  O'Neale, and received advice on statistical testing from I. Doonan.  ...

On Predictive Patent Valuation: Forecasting Patent Citations and Their Types

Xin Liu, Junchi Yan, Shuai Xiao, Xiangfeng Wang, Hongyuan Zha, Stephen Chu
2017 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
Study on real-world data corroborates the efficacy of our approach. Our initiative may also have policy implications for technology markets, patent systems and all other stakeholders.  ...  This work has relied on a long-standing hypothesis that the citation received by a patent is a proxy for knowledge flows or impacts of the patent thus is directly related to patent value.  ...  Among these features, one important indicator is the legal status of a patent.  ...

Ex-ante measure of patent quality reveals intrinsic fitness for citation-network growth [article]

K. W. Higham, M. Governale, A. B. Jaffe, U. Zülicke
2019 arXiv   pre-print
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  ...  Fitness values were estimated based on the quality-indicator variables from TableIusing Eq. (5) with Eq. (2).  ...

Keyword-based patent citation prediction via information theory

Farshad Madani, Martin Zwick, Tugrul Daim
2018 International Journal of General Systems  
The offered prediction method in this article predicts patent citations based on the content of patents.  ...  Current prediction methods use patent citations, but since it may take a long time till a patent is cited by other inventors, identifying impactful patents based on their citations is not an effective  ...  Since we are prediction patent citations based on patent contents, we extract patents based on keywords representing smart building technologies.  ...

Identifying the Age Profile of Patent Citations

Aditi Mehta, Marc Rysman, Timothy S. Simcoe
2006 Social Science Research Network  
Unfortunately, empirical research on the age-profile of patent citations quickly encounters a wellknown identification problem.  ...  Suppose that a patent is born in year b, and consider the number of citations it receives in calendar year t conditional on its age a.  ...  (see . 8 The data set has information on all patents granted from 1963 to 2002 and all patent citations in patents granted from 1975 to 2002.  ...

Patent Value and Citations: Creative Destruction or Strategic Disruption?

David Abrams, Ufuk Akcigit, Jillian A. Popadak
2013 Social Science Research Network  
Using an NPE-derived dataset with patentspecific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations at the high end of value than in the middle  ...  We find evidence of greater use of strategic patents where it would be most expected: among corporations, in fields of rapid development, in more recent patents and where divisional and continuation applications  ...  Finally, we assume α → 1 such that all innovations generate the same return with η innovation size.  ...

2005 arXiv   pre-print
From data on more than 2 million patents and their citations, we extract an attractiveness function, A(k,l), which determines the likelihood that a patent will be cited.  ...  The preferential attachment exponent has been increasing since 1991, suggesting that patent citations are increasingly concentrated on a relatively small number of patents.  ...  for a large fraction of all of the citations.  ...
