TDT is a broad-coverage dependency-annotated treebank of general Finnish. The treebank is annotated in the Universal Dependencies scheme to which is was converted from its original annotation in a minor revision of the Stanford dependency scheme (de Marneffe et al. [1,2]). The primary purpose of the treebank is to support Finnish NLP.
The release currently available for download through the Universal Dependencies project consists of 181K tokens and 13.5K sentences. Further 20K tokens are kept as a secret test set and will be used for a shared task at a later stage.
The treebank consists of a number of different sections. The copyright of the texts remains to their authors (see the list of text sources). All sections of the treebank, as well as the annotation, are released under the Creative Commons Attribution-Share Alike license. Note that this license requires you to refer to the original source of the treebank. This is best achieved by linking to this page in all online derivative works, and citing the paper by Haverinen et al. (2013) below.
The treebank can be queried online using the SETS system.
Any inquiries related to the treebank should be directed to Filip Ginter (firstname.lastname@example.org).
The annotation scheme of the treebank is described in detail in the following technical report:
