Query: Hierarchical Context Enhanced Multi-Domain Dialogue System for
  Multi-domain Task Completion   Task 1 of the DSTC8-track1 challenge aims to develop an end-to-end
multi-domain dialogue system to accomplish complex users' goals under tourist
information desk settings. This paper describes our submitted solution,
Hierarchical Context Enhanced Dialogue System (HCEDS), for this task. The main
motivation of our system is to comprehensively explore the potential of
hierarchical context for sufficiently understanding complex dialogues. More
specifically, we apply BERT to capture token-level information and employ the
attention mechanism to capture sentence-level information. The results listed
in the leaderboard show that our system achieves first place in automatic
evaluation and the second place in human evaluation.
