Description

Patent information is a valuable source of information for research into existing research and understanding the latest research trends, and it is also necessary to conduct a thorough search to avoid infringing on the patent rights of other companies. However, since there are a huge number of patents and it is difficult for non-specialists to grasp the contents of patents due to their unique descriptions, natural language processing technology is expected to be utilized. In this study, as a support for patent searches, the structure of claims is analyzed based on clue clauses, and similarity judgments are made based on the distributed representation of BERT.As a result of the experiment, an accuracy of 0.406 was obtained for the similarity evaluation with patents in the reference literature.
