The Japan Patent Office carries out the patent application technical trend survey for fields in which the development of technologies is expected, or fields to which social attention is being paid, and more than 250 reports and their lists of research papers and patents have been released up to now. Unfortunately, these reports will become obsolete as time goes on. Therefore, we investigate automatic update of patent application technical trend survey reports automatically. In this paper, we propose a method to update lists of research papers and patents, and experimentally confirm the effectiveness of our method.
