Accessibility and Attention in Situated Dialogue: Roles and Regulations

Accessibility theory (Ariel, 1988; Gundel, Hedberg, & Zacharski, 1993) proposes that the grammatical form of referring expression depends on the accessibility of its referent, with greater accessibility permitting more reduced expressions. This paper presents evidence discriminating between Realist and Declarative views of how accessibility will be determined. First, it presents a corpus study ...

Referring and Gaze Alignment: Accessibility is Alive and Well in Situated Dialogue

Accessibility theory (Ariel, 1988; Gundel, Hedberg, & Zacharski, 1993) proposes that the grammatical form of a referring expression depends on the accessibility of its referent, with greater accessibility permitting more reduced expressions. From whose perspective is accessibility measured? Recent experiments (Bard, Hill, & Foster, 2008; de Ruiter & Lamers, submitted) using a joint construction...

REFERRING EXPRESSION GENERATION TOWARDS MEDIATING SHARED PERCEPTUAL BASIS IN SITUATED DIALOGUE By

REFERRING EXPRESSION GENERATION TOWARDS MEDIATING SHARED PERCEPTUAL BASIS IN SITUATED DIALOGUE By Rui Fang Situated human-robot dialogue has received increasing attention in recent years. In situated dialogue, robots/artificial agents and their human partners are co-present in a shared physical world. Robots need to automatically perceive and make inference of the shared environment. Due to its...

Collaborative Models for Referring Expression Generation in Situated Dialogue

In situated dialogue with artificial agents (e.g., robots), although a human and an agent are co-present, the agent’s representation and the human’s representation of the shared environment are significantly mismatched. Because of this misalignment, our previous work has shown that when the agent applies traditional approaches to generate referring expressions for describing target objects with...
