Past work of generating referring expressions mainly utilized attributes of objects and bi- nary 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 ob- jects and n-ary relations among them. The key is to identify groups of objects that are natu- rally recognized by humans. We conducted psy- chological experiments with 42 subjects to col- lect referring expressions in such situations, and built a generation algorithm based on the re- sults. The evaluation using another 23 subjects showed that the proposed method could effec- tively generate proper referring expressions.
