The Natural Language Processing Group of AUEB's Department of Informatics participated in the

European research project INDIGO (Information Society Technologies - Interaction with Personality and Dialogue Enabled Robots), which developed technology for users to

interact with mobile robots. The project's technology combines methods from robotics, computational vision, natural language processing, knowledge representation and inference etc.

AUEB's Department of Informatics developed methods that allow the robot to describe exhibits in different languages from information in an OWL ontology of the Semantic Web. The description is automatically tailored to the users' age and their

interaction history (e.g., previously seen exhibits). The robot is able to vary the intonation of its voice, to use appropriate facial expressions, to turn to the exhibits it describes or compares to, as well as to understand and answer spoken questions

related to the exhibits.

The project was coordinated by the Foundation of Research and Technology - Hellas. The project's

consortium included research centres and universities from several countries.
