We report Year 4 progress in the TRADR project WP5: Persistent models for human-robot teaming. We focused on the analysis, modelling and online-processing of the information-gathering tasks that the human-robot team is performing during a mission, with the goal to enable the robotic system to follow the mission (understand which tasks have been assigned to whom, what the progress is) and provide support for the management of the activities through the agent system and based on the working agreements. The reported work includes further development of team communication processing, ontology modelling, task management support, working agreements. The developed modules are integrated in the TRADR system and were evaluated during the TRADR evaluation exercise.
