Past work of generating referring expressions mainly utilized attributes of objects and binary relations between objects. However, such an approach does not work well when there is no distinctive attribute among objects. To overcome this limitation, this paper proposes a method utilizing the perceptual groups of objects and n-ary relations among them. The(More)
Past work of generating referring expressions mainly utilized attributes of objects and binary relations between objects to distinguish the referent from other objects.

Identifying objects in conversation is a fundamental human capability necessary to achieve efficient collaboration on any real world task. Hence the deepening of our understanding of human referential behaviour is indispensable for the creation of systems that collaborate with humans in a meaningful way. We present the construction of REX-J, a multi-modal(More)
This paper describes a collection of multimodal corpora of referring expressions, the REX corpora. The corpora have two notable features, namely (1) they include time-aligned extra-linguistic information such as participant actions and eye-gaze on top of linguistic information, (2) dialogues were collected with various configurations in terms of the puzzle(More)
In the field of referring expression generation , while in the static domain both intrinsic and extrinsic evaluations have been considered, extrinsic evaluation in the dynamic domain, such as in a situated col-laborative dialog, has not been discussed in depth. In a dynamic domain, a crucial problem is that referring expressions do not make sense without an(More)
This paper deals with understanding referring expressions involving perceptual grouping. The ability to use referring expressions is important for conversational agents aimed at real-world interaction. We conducted a psychological experiment to collect referring expressions involving perceptual grouping. A set of methods to identify referents based on the(More)
Metaphor comprehension involves the generation of novel semantic attributes, especially when a metaphor emphasizes a shared but atypical characteristic of the relevant concepts. The present functional magnetic resonance imaging (fMRI) study explores neural activation during the process of attribute generation known as feature emergence. The participants(More)
