My earlier research in the Laboratory of Dialogue Systems, LSD, at the Faculty of Informatics, Masaryk University. In this research group, we aimed at developing techniques and applications enabling visually impaired people to explore pictures by means of natural language. Our approach was based on ontology-based semantic modeling of graphical data, automated picture annotation, and smart dialogue interaction.
The GATE system (Graphics Accessible To Everyone) was designed and developed to help visually impaired people to explore pictures by the dialogue in natural language. The key concept lies in well-structured annotations backed by formal ontologies that enable us to generate dialogues strategies automatically from the picture content.
