Grounding in Situated Human-Robot Interaction

c⃝Miroslav Janíček. e work investigates the problem of grounding—adding to common ground—in situ-ated human-robot dialogues. Common ground, a special kind of mutual understanding among dialogue parties, is essential for any joint activity and its establishment is thus central to any interaction. When building a robot that is able to interact with a human, we need to tackle the same problem. Not only does the robot need to know what the human expects from it, it also needs to make sure that the human knows what the robot thinks. In other words, both the robot and the human need to work together in order to extend their common ground. We approach this problem by explicitly modelling the beliefs of the agents engaged in the dialogue as a collection of formulas in a formal language. e formulas are given semantics via a translation into a combined modal logic that accounts for their epis-temic status, spatio-temporal framing and content. ree classes of epistemic statuses are modelled: private, attributed and shared. Private beliefs are private to the agent, at-
