Incremental speech understanding in a multimodal web-based spoken dialogue system
In most spoken dialogue systems, the human speaker interacting with the system must wait until after finishing speaking to find out whether his or her speech has been accurately understood. The verbal and nonverbal indicators of understanding typical in human-to-human interaction are generally …

Relational dialogue
… agents are increasingly common in everyday life. Dialogue with these agents is often limited to the task at hand, and is not focused on conversation as a shared social experience. Previous work has demonstrated that strengthening the user-agent relationship increases the agent's efficacy, and …

Symmetric multimodal interaction applied to database design and normalization
… computers to carry out symmetric, multimodal dialogues with humans, thereby providing a more natural human-computer interaction. To do so, we modified and extended Adler's Multimodal Interactive DialOgue System (MIDOS) to be a more flexible and domain-independent platform for supporting …

PLUTO : a preprocessor for multilingual spoken language generation
… for a surface realization component in a spoken dialogue system. The architecture divides the surface realization task in two: (1) modification of the meaning representation to adhere to the constraints of the target language, and (2) string production. Each subtask is handled by a separate …

The Attention-Hesitation Model. A Non-Intrusive Intervention Strategy for Incremental Smart Home Dialogue Management
… is how human attention can be incorporated into dialogue management, to improve Human-Agent Interaction (HAI) in smart homes. Research shows that speakers’ hesitations are often produced as a reaction to the listener’s inattentiveness in HHI. Furthermore, they can improve the listeners’ …

Reinforcement learning for trading dialogue agents in non-cooperative negotiations
Recent advances in automating Dialogue Management have been mainly made in cooperative environments -where the dialogue system tries to help a human to meet their goals. In non-cooperative environments though, such as competitive trading, there is still much work to be done. The complexity of such …
