CoNLL Shared Task 2007 Call for Participation

The shared task of the Conference on Computational Natural Language Learning (CoNLL) 2007 will for the second year running be devoted to dependency parsing. Unlike in 2006, there will be two separate tracks:

  1. Multilingual Track: The first track of the shared task will be organized in the same way as the 2006 task (see with annotated training and test data from a wide range of languages, which should be processed with one and the same parsing system. The languages this year will be Arabic, Basque, Catalan, Chinese, Czech, English, Greek, Hungarian, Italian, and Turkish.
  2. Domain Adaptation Track: The second track of the shared task will investigate techniques for adapting current parsing technologies to domains outside of the data from which they were trained. The single language for this track will be English and the data will consist of 1) a large annotated training set of news related text, 2) a small annotated development data set of non-news text, 3) one or more small test data sets of non-news text, 4) large unlabeled corpora extracted from the domains of the training, development and test data.

The shared task will be part of the joint EMNLP-CoNLL conference to be held in conjunction with ACL-07 in Prague, June 28-30, 2007. The important dates for the shared task are as follows (please note that some dates have been shifted slightly since the first call):

Registration of participants January 20, 2007
Release of training (and development) data January 29, 2007
Release of test data March 26, 2007
Submission of test runs March 30, 2007
Submission of papers April 14, 2007
Notification of acceptance April 25, 2007
Submission of final version of papers May 9, 2007
EMNLP-CoNLL conference June 28-30, 2007

In order to receive future calls and other information about the shared task, participants should register their intent to participate, in either or both of the two tracks, by sending an e-mail to conll07st [at] Although the deadline for registration is not until January 20, 2007, we recommend participants to register as early as possible, in order not to miss any information.
