| + | ==== Obtaining and License ==== | ||
| + | |||
| + | There does not seem to be any regular distribution channel for the Greek Dependency Treebank. The CoNLL 2007 version had a restricted license for the duration of the shared task only. Republication of the CoNLL version in LDC is planned but it has not happenned yet. In the meantime, one can ask Prokopis Prokopidis (prokopis (at) ilsp (dot) gr) about availability of the corpus. | ||
