Towards Domain Graphs and Dialogue Graphs for Conversational Grounding in HRI

Abstract

Knowledge graphs have been used to improve robot dialogues by providing more sophisticated world knowledge. We now propose a new role for knowledge graphs in GenAl-based HRI that aims to reduce dialogue errors by better conversational grounding. This approach uses both domain knowledge graphs and dialogue history graphs, constructing shared knowledge via entity linking. We present first steps towards these aims, and also address sustainability by supporting the use of smaller models.
