The UD_Czech-CLTT treebank is based on the Czech Legal Text Treebank 2.0, created at the Charles University in Prague.
CLTT is a collection of 1121 manually annotated dependency trees. CLTT consists of two legal documents: The Accounting Act (563/1991 Coll., as amended; Czech: “Zákon o účetnictví”; in sentence ids: “zakon.iso”) and Decree on Double-entry Accounting for undertakers (500/2002 Coll., as amended; Czech: “Vyhláška, kterou se provádějí některá ustanovení zákona č. 563/1991 Sb., o účetnictví, ve znění pozdějších předpisů, pro účetní jednotky, které jsou podnikateli účtujícími v soustavě podvojného účetnictví”; in sentence ids: “vyhlaska.iso”).
