5  Systems and Utilities

5.1  The numbers System

In Skantze and Schlangen, [2009] ("Incremental dialogue processing in a micro-domain") we presented our work on an end-to-end demonstrator system that used incremental processing throughout. While working in a very limited domain (a "micro-domain" in the terms of Edlund et al., [2008]), the system covered a substantial number of behaviours (clarification, feedback giving).

5.2  The pento System

The system presented in Buß et al., [2010] ("Collaborating on utterances with a spoken dialogue system using an isu-based approach to incremental dialogue management") was an attempt to scale up what we did for the NUMBERS system. In that system, uncertainty could only occur regarding the signal identity. In the PENTO system, there can also be uncertainty regarding intended referents, and the system and the user can be seen as working together in producing effective referring expressions.

5.3  The travel System

Buß and Schlangen, [2011] sketches a system that moves the incremental approach to a more common domain, travel information.

5.4  Utilities for Handling Incremental Data

Bringing in a timing dimension into the communication between modules makes it much harder to handle resulting data (such as system logs). In von der Malsburg et al., [2009] ("Telida: A package for manipulation and visualisation of timed linguistic data") we presented our work on developing tools for dealing with such data. This includes a perl package for querying and manipulating temporally aligned data, as well as a visualiser that can handle the two temporal dimensions that are relevant in incremental processing (when was a hypothesis formulated / communicated, and about what time does the hypothesis speak?).
