The UD_Czech-CLTT treebank is based on the Czech Legal Text Treebank 1.0, created at Charles University in Prague.

CLTT is a collection of 1125 manually annotated dependency trees. CLTT consists of two legal documents: The Accounting Act (563/1991 Coll., as amended) and Decree on Double-entry Accounting for undertakers (500/2002 Coll., as amended).

See the following websites for more information on CLTT 1.0:


We wish to thank all of the contributors to the original CLTT annotation effort, including Barbora Hladká, Vincent Kríž and Zdeňka Urešová.
