Sprachtechnologie und Multilingualität

Wir sind ein Team am MLT-Labor am DFKI, die sich auf neuronale maschinelle Übersetzung (MT) und mehrsprachige Anwendungen spezialisiert hat.

Maschinelle Übersetzung ist der automatisierte Prozess der Umwandlung von Eingaben in einer Sprache in eine andere Sprache. Wir arbeiten sowohl in der Text- als auch in der Gebärdensprachenübersetzung unter Verwendung von Techniken des Deep Learning. Neben der Entwicklung generischer MÜ-Systeme, spezialisieren wir uns auf die maschinelle Übersetzung in Bereichen wie Sprachen mit geringen Ressourcen, hochgradig mehrsprachige Umgebungen oder Dokumenten- und Dialogübersetzung. 

Wir beteiligen uns an Projekten der D&R- und TR-Gruppen, zu denen wir mit maschineller Übersetzung und mehrsprachigen Technologien beitragen:
