2006 CoNLL Shared Task - Arabic & Czech consists of dependency treebanks used as part of the CoNLL 2006 shared task on multi-lingual dependency parsing. The Conference on Computational Natural Language Learning (CoNLL) is accompanied every year by a shared task intended to promote natural language processing applications and evaluate them in a standard setting. In 2006, the shared task was devoted to the parsing of syntactic dependencies using corpora from up to thirteen languages. The task aimed to define and extend the then-current state of the art in dependency parsing, a technology that complemented previous tasks by producing a different kind of syntactic description of input text. More information about CoNLL and the 2006 shared task are available respectively at: http://ifarm.nl/signll/conll and http://ilk.uvt.nl/conll.
