Computer Science Colloquium - "Walk This Way: Natural Language Interaction for City Exploration"

Johan Boye will discuss some methods for robust spoken natural-language interaction between humans and machines in a rapidly changing spatial context. The scenario is that of a spoken dialogue system helping pedestrians in a city; people carrying a mobile phone with a GPS receiver, and who are in need of information about directions or services in the immediate vicinity. In order to give such directions, and to be able to understand the user’s utterances, the system needs to know how the user refers to buildings and other entities in the vicinity, and which entities the user finds particularly noteworthy or salient. Rather than referring to some theory of salience from cognitive psychology (of which there are plenty), we show that such knowledge can be learnt directly from data.
