• Abstract: Tangled multi-party dialogue context leads to challenges for dialogue reading comprehension, where multiple dialogue threads flow simultaneously within the same dialogue history, thus increasing difficulties in understanding a dialogue history for both human and machine. Dialogue disentanglement aims to clarify conversation threads in a multi-party dialogue history, thus reducing the difficulty of comprehending the long disordered dialogue passage. Existing studies commonly focus on utterance encoding with carefully designed feature engineering-based methods but pay inadequate attention to dialogue structure. This work designs a novel model to disentangle multi-party history into threads, by taking dialogue structure features into account. Specifically, based on the fact that dialogues are constructed through successive participation of speakers and interactions between users of interest, we extract clues of speaker property and reference of users to model the structure of a long dialogue record. The novel method is evaluated on the Ubuntu IRC dataset and shows state-of-the-art experimental results in dialogue disentanglement.

  In open domain multi turn dialogue generation, it is essential to modeling the contextual semantics of the dialogue history. Previous research had verified the effectiveness of the hierarchical recurrent encoder-decoder framework on open domain multi turn dialogue generation. We propose a static and dynamic attention-based approach to model the dialogue history and then generate open domain multi turn dialogue responses.

  This paper proposes to model multi-turn dialogues from a topic-aware perspective. We use a dialogue segmentation algorithm to split a dialogue passage into topic-concentrated fragments in an unsupervised way. We also present a novel model, Topic-Aware Dual-Attention Matching (TADAM) Network, which takes topic segments as processing elements.

  Abstractive dialogue summarization has long been viewed as an important standalone task in natural language processing. We propose a novel type of dialogue summarization task - STRUctured DiaLoguE Summarization. We show that our STRUDEL dialogue comprehension model can significantly improve the dialogue comprehension performance of transformer encoder language models.
