Training, development and text data (the same used for the Sentence-level Quality Estimation task) consist of English-German triplets (source, target and post-edit) belonging to the Information Technology domain and already tokenized. Training and development respectively contain 12,000 and 1,000 triplets, while the test set contains 2,000 instances. Target sentences are machine-translated with the KIT system. Post-edits are collected by TextampForm from professional translators. All data is provided by the EU project QT21 (/http://www.qt21.eu/).
