- Abstract: Deep learning is providing very positive results in areas related to
conversational interfaces, such as speech recognition, but its potential
benefit for dialog management has still not been fully studied. In this paper,
we perform an assessment of different configurations for deep-learned dialog
management with three dialog corpora from different application domains and
varying in size, dimensionality and possible system responses. Our results have
allowed us to identify several aspects that can have an impact on accuracy,
including the approaches used for feature extraction, input representation,
context consideration and the hyper-parameters of the deep neural networks
employed.

Dialogues [0.716879432974126]
Graph neural networks (GNNs) show a remarkable superiority by reaching a success rate above 80% with only 50 dialogues, when learning from simulated experts.
We suggest to concentrate future research efforts on bridging the gap between human data, simulators and automatic evaluators in dialogue frameworks.

Task-oriented dialogue systems are designed to achieve specific goals while conversing with humans.
In practice, they may have to handle simultaneously several domains and tasks.
We show that structured policies based on graph neural networks combined with different degrees of imitation learning can effectively handle multi-domain dialogues.

Embeddings [38.51601073819774]
Learning task-oriented dialog policies via reinforcement learning typically requires large amounts of interaction with users.
We propose to leverage data from across different dialog domains, thereby reducing the amount of data required from each given domain.
We show how this approach is capable of learning with significantly less interaction with users, with a reduction of 35% in the number of dialogs required to learn, and to a higher level of proficiency than training separate policies for each domain on a set of simulated domains.

To utilize segment act flows, sequences of segment acts, for evaluation, we develop the first consensus-based dialogue evaluation framework, FlowEval.

We propose the Conversational-Logic-Injection-in-Neural-Network system (CLINN) where explicit knowledge is coded in semi-logical rules.

Task-oriented dialog systems are attracting more and more attention in academic and industrial communities.
We discuss three critical topics for task-oriented dialog systems: (1) improving data efficiency to facilitate dialog modeling in low-resource settings, (2) modeling multi-turn dynamics for dialog policy learning, and (3) integrating domain knowledge into the dialog model.

Multi-role dialogue understanding comprises a wide range of diverse tasks such as question answering, act classification, dialogue summarization etc.

In this work, we investigate dialogue context representation learning with various types unsupervised pretraining tasks.
