| Abstract(in English) | In this paper, we propose a dialogue manager using Partially Observable Markov Decision Processes (POMDP) that can treat ambiguous information. It can recover from the recognition error while naturally dialogue. However, a dialogue manager produced with a POMDP has been limited to artificial small tasks because calculation of reinforcement learning becomes complicated as the number of state variables increases. We also propose a variation of the classic POMDP incorporating hierarchical reinforcement learning. It can deal with large task than traditional system. The results show the effectiveness of proposed method. |
