Abstract: | We present the MATCH corpus, a unique data set of 447 dialogues in which 26 older and 24 younger adults interact with nine
different spoken dialogue systems. The systems varied in the number of options presented and the confirmation strategy used.
The corpus also contains information about the users’ cognitive abilities and detailed usability assessments of each dialogue
system. The corpus, which was collected using a Wizard-of-Oz methodology, has been fully transcribed and annotated with dialogue
acts and “Information State Update” (ISU) representations of dialogue context. Dialogue act and ISU annotations were performed
semi-automatically. In addition to describing the corpus collection and annotation, we present a quantitative analysis of
the interaction behaviour of older and younger users and discuss further applications of the corpus. We expect that the corpus
will provide a key resource for modelling older people’s interaction with spoken dialogue systems. |
