Identification of interactivity sequences in interactions with spoken dialog systems

Abstract

The MeMo workbench is an existing system for semi-automated usability testing and following a rule based approach. The rules which are actually used have been obtained from usability expert knowledge as well as from empirical observations in a more or less uncontrolled way. In this paper we present a sociotechnical approach for finding rules, which implement probable user behavior, in a structuralized and more realistic way. We will give short introduction to the MeMo workbench followed by the description of our approach and the resulting experiment.
