SUD is an annotation scheme for syntactic dependency treebanks, and has a nearly perfect degree of two-way convertibility with the Universal Dependencies scheme (UD). Contrary to UD, it is based on syntactic criteria (favoring functional heads) and the relations are defined on distributional and functional bases.
To see more examples, head over to the universal SUD guidelines , or to the dedicated French and Naija pages.
Automatic conversion to the SUD format is available here .
