Grounding in human-robot interaction: two years of behaviour trees and knowledge representations

Time: Fri 2020-09-25 15.15

Lecturer: Nils Axelsson

Location: Physically at the division (Fantum) and streamed online

  My PhD project is an exploration of how the grounding state of
information can be modelled and tracked in a conversation between a
human and a robot. In this presentation, I will present what I have done
in the first two years of my PhD position, with a focus on the second
year. There will be a brief recap of the first year, including the
publication "Modelling Adaptive Presentations in Human-Robot Interaction
using Behaviour Trees" (SigDial 2019), for the benefit of those at TMH
who were not present at my first talk.

  The main point of the presentation is a presentation of our IVA
2020 publication "Using knowledge graphs to empower a grounding-based
dialogue system", where we explored how knowledge graph representations
(Wikidata, DBPedia) could be used to not only synthesise a presentation
for a presenting system, but also be used to keep track of grounded
information (user modelling). I will also recap some video annotation
work that took up most of late 2019.
