Outline of Final Research Achievements

We confirmed that bar exam multiple choice problem can be solved by PROLEG manually in FY2014. However, with regard to the bridging rules we made manualy, the scope of application of the problem was narrow and we found that we can not deal with new problems. So in FY2015 we examined a method different from the bridging rule, but it was not successful. In FY2016, we devised a method using a question answering system that responds to the value in the predicate. We carrie out the initial experiment and we found that substitution of some value can be obtained, but that it is still necessary to extend the method further.
