特許分類子を用いた技術構造推移分析に関する研究

抄録

This paper provides the technological structure transition of FPGA through the patent analyseswith making graphs using classification codes in patent information. Knowledge extraction from patentinformation has been made so far, but conventional patent analysis methods which depend on personalheuristic knowledge make it hard to extract the technological structure. We are focusing on the classificationcodes in patents that are assigned to define the patent's technological fields. With the proposed method, wewere succeeded in extracting the technological structure transition of FPGA.
