The work then presents a generative multilingual parsing model in which dependent ordering parameters are conditioned on word order typology, obtained from WALS.
the paper utilises the following word order features (henceforth WALS Basic word Order, WBO): 81A (Subject Verb and Object), 85A (Adposition and Noun), 86A (Genitive and Noun), 87A (Adjective and Noun), 88A (Demonstrative and Noun) and 89A (Numeral and Noun).
