2018 2018 IEEE International Conference on Industrial Engineering and Engineering Management (IEEM)  
In our research, clustering of patent citation networks by Stochastic Block Model was done with the aim of enabling corporate managers and investors to evaluate the scale and life cycle of technology.  ...  Because even if the cluster of a patent has no hope of growing, we recognize the patent is important if PageRank or other ranking score is high.  ...  Chang [11] study employs a panel threshold regression model to test whether the patent i-index has a threshold effect on the relationship between patent citations and market value in the pharmaceutical  ...
