| Outline of Final Research Achievements |
This research project aims to build a computer system that can understand and interpret documents about historical events in the history of Japan or the World. To achieve this goal, we have proposed a novel approach of using a world model that can represent various historical events and autonomous time evolution. Specifically, we represent the movement of historical figures with hidden Markov models and infer their movement paths using the EM algorithm. To examine the effectiveness of the approach, we have conducted experiments using the Japanese Wikipedia text and shown that the proposed approach can estimate the existence probability of historical figures with a certain level of accuracy.
