Solving exam questions based on integration of physical model understanding and natural language processing

Simulation modules for dynamics, electromagnetics and electrical circuit were developed, for example spring, pulley and so on, in order to realize physical simulation based on the Modelica system. Regarding the wave phenomenon, we developed an original simulator. We also considered and designed "logical form" that connects result of natural language processing and the physics simulator. Disambiguation function was designed based on contrariety detection between the simulation results and given natural language sentences. We evaluated the proposed method with applying to a real exam performed by a cram school; the system got the score 39 among 100 (T-score: 48.3).
