Types of Systems Studied
- Systems that make some use of language technology (LT), such
as:
- (Multilingual) information retrieval systems
- Systems for extracting information from texts
- Spoken dialog systems
Goal
- To advance understanding of:
- methodologies for empirical studies of the usability of
LT systems
- key usability issues that arise with particular types of
LT system
Specific Points of Emphasis
- Studying the usability of an entire system that has an LT component
- as opposed to evaluating just the LT component
- Detailed understanding of how users deal with the system
- as opposed to evaluation of their overall success and satisfaction
- Use of eye tracking technology as one way of achieving detailed
understanding
Context and Funding
The Evaluation Center is part of the project COLLATE,
which has been funded by the German
Federal Ministry of Education and Research (BMB+F) since April
2001.
