Question Answering in Spacebook
Spacebook is a speech-driven, hands-free, eyes-free mobile application for pedestrian navigation and exploration in urban environments. This talk is an overview of the system, with a focus on pedestrian exploration and question answering techniques used in combination with GIS technology in the dialogue system. Besides open questions about famous people and points of interests in the city, Spacebook also allows deictic questions such as: “What is this monument?” or “Who was he” (e.g. in front of David Hume’s statue). Two series of experiments were carried out with human subjects in the streets of Edinburgh. I will report on the results currently available and some of the specific challenges we encountered with the deployed system.
Some of this work has been presented in:

Spacebook is a EU-funded FP7 project.
