Arborest – a Growing Treebank of Estonian

Treebank creation is a very labor-consuming task, especially if the applications intended include machine learning, gold standard parser evaluation or teaching, since only a manually checked syntactically annotated corpus can provide optimal support for these purposes. There are, however, possibilities to make the annotation process (partly) automatic, saving (manual) annotation time and/or allowing the creation of larger corpora. Whenever possible, existing resources – both corpora and grammars – should be reused.
