| Abstract: | Purpose/significance]The paper is to reveal the technology development process of a certain field.Method/process]On the basis of deepening and expanding the connectivity algorithm,the paper puts forwards a main path analysis algorithm for patent citation.According to the strategy of bounded depth-first searching,the paper uses the traversal number of search path to measure the weight of patent citation path,follows the local optimal rule of traversal number to find the main path through the whole patent citation network.Also,the paper takes fuel cell for example,collects patent data and patent citation data to build a patent citation network in the fuel cell field.At last,the paper obtains the main path of fuel cell field by using Pajek for connection analysis.Result/conclusion]The results show that,a few patent citation paths aggregate most weights of the patent citation network,which reflects the main path mining effect and verifies the feasibility and effectiveness of the algorithm. |
