Preface
The short papers reproduced here describe implemented systems that were presented at the demo session of EACL-2009 in Athens, March 30 - April 3, 2009. Upon the call for demos, a total of 33 papers were submitted. Each submission was reviewed by at least two members of the programme committee. Based on these reviews, 17 submissions were accepted for presentation at the demo session and publication in the conference proceedings. I would like to thank the general chairs and the local organisers, without whom it would have been impossible to put together such a strong demo programme. In particular, I would like to thank the members of the programme committee for the excellent job they did in reviewing the submissions. Jš rn Kreutel o EACL 2009 Demonstration Chair
