Building of commonsense knowledge for home robotic services: 'bring something' and 'tidy things up'

Abstract

Sharing commonsense knowledge would be one of the most important keys for interaction between human and service robot. However, the complication of human commonsense makes extracting appropriate information for service robot difficult. This paper presents our approach to build the basic-level knowledge network (BKN) as a commonsense and how it is used for robotic services. In this paper, we focused on two services. One is ‘bring something’ and the other is ‘tidy things up’. We found that for ‘bring something’, relationship between object-activity is important, and for ‘tidy things up’ service, knowledge about relationship between object-place is more important. To perform these services at the practical level, many relative knowledge should be prepared. Moreover, we would like to introduce how BKN is built and show the demonstration result in which how BKN is useful for actual services in real environment.
