Human-Robot Dialogues for Explaining Activities

The paper focuses on dialogue modelling that enables communication between users and social robots, on topics that concern experience and knowledge of people in service industries, especially in elder-care services. We discuss different knowledge types and explication of knowledge using dialogues based on goal-oriented ontologies. We present an architecture and an example of a dialogue system that allows humans to communicate with a robot partner and be engaged in interactions concerning activities related to basic care-giving tasks.
