CoNLL-2013 Shared Task: Grammatical Error Correction

CoNLL-2013 will continue the CoNLL tradition of having a high profile
shared task in natural language processing. This year's shared task
will be grammatical error correction. A participating system in this
shared task is given short English texts written by non-native
speakers of English. The system detects the grammatical errors present
in the input texts, and returns the corrected texts.

This task has gained popularity recently with the organization of the
HOO (Helping Our Own) shared tasks in 2011 and 2012. In the most

*********************************************************

SCOPE

Hierarchies are becoming ever more popular for the
organization of documents, particularly on the Web
(e.g. Web directories). Along with their widespread
use comes the need for automated classification of
new documents to the categories in the hierarchy.
Research on large-scale classification so far has
