¢£Introduction of recent research
My recent main research is to develop legislation supporting web systems. The approach of the research is based on similarities between legislation process and software development process. This approach has main 2 types as the follows:
1) SDL (Software Defined Law) Approach: using Python for representing laws in the inside of our developed system for legislation supporting.
2) Analogical Approach: using templates of laws or rules composed automatically with AI from many laws and rules already exist.
Especially, in our research work based on the approach 2, we have already provided our legislation supporting system to all of the local governments in Japan since 2012. The system is called "eLen", recently released by Kagoshima University's eLen Site(in Japanese). Furthemore, one of my resent research projects with the approach includes a project adopted as a CREST program by JST.
