UD_Finnish treebank (Turku Dependency Treebank)

UD_Finnish treebank is a broad-coverage dependency-annotated treebank of general Finnish annotated in the Universal Dependencies scheme. The treebank has about 200,000 words and 15,000 sentences.

The original Turku Dependency Treebank (TDT) was annotated in the Stanford dependency scheme, and later converted into the UD scheme. The UD version of the treebank is the main version, which is maintained. The UD version is distributed trough the UD project (data). The original version (TDT) is also available upon request but it is not maintained anymore. The original treebank has also additional data available regarding the annotation process (double annotations, timestamps etc).

Finnish Internet Parsebank

A mass-scale corpus of Internet Finnish with automatic syntactic analysis. Currently includes about 3.7 billion tokens.

The project has three aims: 1) The creation of a language resource with automatic morphological and syntactic analyses, 2) The classification of the entire Parsebank to coherent subcorpora, 3) The creation of an online user interface

Online search for words and their contexts: Finnish Internet Parsebank corpus in NoSketchEngine

Semantic similarity of words: An online demo which lets you query semantically similar words using a word2vec model trained on the Parsebank data, Embedding models in binary form are available here.

Word frequency list: A Finnish word frequency list can be downloaded at It’s calculated from the Parsebank data and sorted in descending order. If you use this in your research, please cite us.

Finnish Propbank

Finnish PropBank is a collection of predicates annotated with their sense and arguments. The data builds on top of the Turku Dependency Treebank (TDT), more specifically its Universal Dependencies version.
