• Abstract: A target-guided proactive dialogue system aims to steer conversations proactively toward pre-defined targets, such as designated keywords or specific topics. During guided conversations, dynamically modeling conversational scenarios and intent keywords to guide system utterance generation is beneficial; however, existing work largely overlooks this aspect, resulting in a mismatch with the dynamics of real-world conversations. In this paper, we jointly model user profiles and domain knowledge as conversational scenarios to introduce a scenario bias that dynamically influences system utterances, and employ intent-keyword bridging to predict intent keywords for upcoming dialogue turns, providing higher level and more flexible guidance. Extensive automatic and human evaluations demonstrate the effectiveness of conversational scenario modeling and intent keyword bridging, yielding substantial improvements in proactivity, fluency, and informativeness for target-guided proactive dialogue systems, thereby narrowing the gap with real world interactions.

  Goal-directed dialogue systems aim to proactively reach a pre-determined target through multi-turn conversations. Key to achieving this task lies in planning dialogue paths that smoothly and coherently direct conversations towards the target. We propose a coherent dialogue planning approach that uses a process to model the temporal dynamics of dialogue paths.

  Dialogue state tracking (DST) aims to track human-machine interactions and generate state representations for managing the dialogue. Recent advances in machine reading comprehension predict both categorical and non-categorical types of slots for dialogue state tracking. We formulate and incorporate dialogue acts, and leverage recent advances in machine reading comprehension to predict both categorical and non-categorical types of slots for dialogue state tracking.

  Seq2seq neural response generation approaches do not have explicit mechanisms to control the content or style of the generated response. We propose using a dialogue policy to plan the content and style of target responses in the form of an action plan. We demonstrate that a basic dialogue policy that operates at the sentence level generates better responses in comparison to turn level generation.
