"Visualization" of decarbonization-related patent technologies by patent domainspecific BERT

Abstract

We trained a classifier to determine whether a technology in the patent literature corresponds to a decarbonization-related technology or not, using BERT pre-trained on the patent documents and the corpus of decarbonization-related patents we collected. The trained BERT model was also used to conduct macro analysis of Japanese published patent gazettes applied after 2000 to visualize the decarbonizationrelated patent technologies in Japan.
