• Title: Exploring Recurrent, Memory and Attention Based Architectures for Scoring Interactional Aspects of Human-Machine Text Dialog
• Authors: Vikram Ramanarayanan and Matthew Mulholland and Debanjan Ghosh
• Abstract summary: This paper builds on previous work in this direction to investigate multiple neural architectures. We conduct experiments on a conversational database of text dialogs from human learners interacting with a cloud-based dialog system. We find that fusion of multiple architectures performs competently on our automated scoring task relative to expert inter-rater agreements.

• Abstract: An important step towards enabling English language learners to improve their conversational speaking proficiency involves automated scoring of multiple aspects of interactional competence and subsequent targeted feedback. This paper builds on previous work in this direction to investigate multiple neural architectures -- recurrent, attention and memory based -- along with feature-engineered models for the automated scoring of interactional and topic development aspects of text dialog data. We conducted experiments on a conversational database of text dialogs from human learners interacting with a cloud-based dialog system, which were triple-scored along multiple dimensions of conversational proficiency. We find that fusion of multiple architectures performs competently on our automated scoring task relative to expert inter-rater agreements, with (i) hand-engineered features passed to a support vector learner and (ii) transformer-based architectures contributing most prominently to the fusion.

• A Static and Dynamic Attention Framework for Multi Turn Dialogue Generation [37.79563028123686]
  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.

  Well-structured topic flow can leverage background information and predict future topics to help generate controllable and explainable responses. We present a new framework for dialogue structure learning to effectively explore topic-level dialogue clusters as well as their transitions with unlabelled information. Experiments on two popular open-domain dialogue datasets show our model can generate more coherent responses compared to some excellent dialogue models.

  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.
