Abstract:
The field of intelligent tutoring systems has seen recent developments
moving towards adding natural language capabilities to computer-based
tutoring. Indeed, one-on-one instruction has been shown to achieve
higher learning gains than other forms of teaching. In order to be
able to interact with a student through the medium of natural
language, a system must have a model of how such tutorial dialogues
can progress and what utterances are licenced. However there is still
a large gap between general computational models of dialogue and the
ad hoc models used in current language-enabled intelligent tutoring
systems which prevents tutoring systems from taking advantage of
general conversational expertise.
In this talk I will argue for modelling tutorial dialogue as an
instance of mixed-initiative task-oriented dialogue between unequal
conversational partners, the student and the tutor. I will present
data from two Wizard-of-Oz experiments and show how a computational
theory of the pragmatic phenomenon of grounding (achieving mutual
understanding in conversation) can be used to maintain the belief
states of students and tutors and to give an operational model of
subdialogues in tutorial interactions.
The Dublin Computational Linguistics Research Seminar series is run
jointly by Dublin City University, Dublin Institute of Technology,
Trinity College Dublin, and University College Dublin.
The 2008/2009 DCLRS is hosted by the Computational Linguistics Group
of Trinity College Dublin, with support from the the Centre for
Computing and Language Studies, Centre for Language and Communication
Studies, the School of Computer Science and Statistics, and the Centre
for Next Generation Localisation.
