Shared Task Data
The training, development and evaluation data sets that were used in the shared task are now publicly available for download in Lindat (http://hdl.handle.net/11234/1-3728). The package also includes scripts used during the shared task by the organizing team, as well as the primary submissions (parsed data) of each participating team.
Training and Development Data
Within the .tgz package, the datasets are organized similarly to UD releases, that is, CoNLL-U files are in subfolders that represent treebanks rather than languages. Each folder contains the README and LICENSE files (all treebanks come with some type of open license but some of them are restricted for non-commercial use). Besides gold-standard CoNLL-U files, there are also raw text files; this is the form which the participating systems should expect as input. Some folders do not contain data because the corresponding UD treebank contains only test data and no training data. Participants can expect that data from such treebanks will be part of the evaluation; while they cannot use the actual data from those treebanks to train their systems, they may use the information from the README files (e.g. to learn what genres the treebank contains). There is always at least one other treebank for the same language that has training data.
See the task description for more details on what data can be used in the shared task.
Gold and Blind Data by Language
Besides being included in the train-dev package described above, the development data is also available in the form in which the test data will be provided. Participants can use this data to test their system in similar conditions as those in which the test phase will run. Here the blind package contains simply one text file per language, and the system submission should mimic the structure of the gold package.
