Language Technology World (LT World) is an ontology-based virtual information center on the wide spectrum of technologies for dealing with human languages. It is a free service provided to the R&D community, potential users of language technologies, students and other interested parties by the German Research Center for Artificial Intelligence (DFKI).

Design and construction of the virtual information center formerly has been supported by a grant of the German Ministry for Education and Research (BMBF) through the collaborative project COLLATE Computational Linguistics and Language Technology for Real Life Applications from 2000 - 2006.

Current LT World Team: Hans Uszkoreit, Brigitte Jörg, Alastair Burt, Lucia Ingala-Hornung

Past Team Members: Witold Drozdzynski, Tilman Wegst, Gregor Erbach, Elizabeth de Sousa Pinto

Advisory Board: Steven Bird, Martin Kay, Sharon Oviatt, Donia Scott, Oliviero Stock, Hans Tillmann

The LT World portal has been launched with improved architecture. The portal will be further maintained and content updates are on the list of ToDos.

Acknowledgements:
One major source of knowledge in language technology is the Survey of the State of the Art in Human Language Technology. For many topics, this source has provided the best references for our virtual information center. We thank the authors, editors and sponsors of this resource for their service to the field. The Survey was jointly funded by the European Commission and by the National Science Foundation of the USA.

Another important resource for LT World is the Natural Language Software Registry, the world wide database on language technology systems which has been operated by DFKI under the auspices of the Association of Computational Linguistics (ACL).

We are grateful to our summer students, research assistants and interns for their hard work in manual data collection and classification:

Nuria Bertomeu, Mireia Farrús Cabeceran, Iris Kersten, Mirjam Kessler, Elizabeth de Sousa Pinto, Feilong Xu
