• Abstract: 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.

  Task-Oriented Dialogue (TOD) systems assist users in completing tasks through natural language interactions. In this work, we introduce HierTOD, an enterprise TOD system driven by hierarchical goals and can support composite. Our system implementation unifies two TOD paradigms: slot-filling for information collection and step-by-step guidance for task execution.

  We propose a novel framework, namely USDA, to incorporate the sequential dynamics of dialogue acts for predicting user satisfaction. USDA incorporates the sequential transitions of both content and act features in the dialogue to predict the user satisfaction. Experimental results on four benchmark goal-oriented dialogue datasets show that the proposed method substantially and consistently outperforms existing methods on USE.

  In a customer service system, dialogue summarization can boost service efficiency by creating summaries for long spoken dialogues. In this work, we focus on topic-oriented dialogue summarization, which generates highly abstractive summaries. We propose a novel topic-augmented two-stage dialogue summarizer ( TDS) jointly with a saliency-aware neural topic model (SATM) for topic-oriented summarization of customer service dialogues.

  We propose the Point-Or-Generate Dialogue State Tracker (POGD) POGD points out explicitly expressed slot values from the user's utterance, and generates implicitly expressed ones based on slot-specific contexts.
