Addressing how-to questions using a spoken dialogue system
Silvia Quarteroni, Patrick Saint‐Dizier · 2009
In this document, we illustrate how complex questions such as procedural (how-to) ones can be addressed in an interactive format by means of a spoken dialogue system. The advantages of interactivity and in particular of spoken dialogue with respect to standard Question Answering settings are numerous. First, addressing user needs that do not necessarily arise in front of a computer; moreover, a spoken or multimodal answer format can often be better suited to the user's need. Finally, the procedural nature of the information itself makes iterative question formulation and answer production particularly appealing.
