- Abstract: While multi-party conversations are often less structured than monologues and
documents, they are implicitly organized by semantic level correlations across
the interactive turns, and dialogue discourse analysis can be applied to
predict the dependency structure and relations between the elementary discourse
units, and provide feature-rich structural information for downstream tasks.
However, the existing corpora with dialogue discourse annotation are collected
from specific domains with limited sample sizes, rendering the performance of
data-driven approaches poor on incoming dialogues without any domain
adaptation. In this paper, we first introduce a Transformer-based parser, and
assess its cross-domain performance. We next adopt three methods to gain domain
integration from both data and language modeling perspectives to improve the
generalization capability. Empirical results show that the neural parser can
benefit from our proposed methods, and performs better on cross-domain dialogue
samples.

We propose enhancing dialogue disentanglement by taking full advantage of the dialogue discourse characteristics.
We develop a structure-aware framework to integrate the rich structural features for better modeling the conversational semantic context.

We pre-train a model that understands the discourse structure of multi-party dialogues, namely, to whom each utterance is replying.
To fully utilize the unlabeled data, we propose to treat the discourse structures as latent variables, then jointly infer them and pre-train the discourse-aware model.

How to build and use dialogue data efficiently, and how to deploy models in different domains at scale can be critical issues in building a task-oriented dialogue system.
We propose a novel manual-guided dialogue scheme, where the agent learns the tasks from both dialogue and manuals.
Our proposed scheme reduces the dependence of dialogue models on fine-grained domain ontology, and makes them more flexible to adapt to various domains.

Experimental results demonstrate that a speaker-aware extension on the best-performing model leads to gains in both the standard and conversational evaluation settings.
