The Hindi UD treebank is based on the Hindi Dependency Treebank (HDTB), created at IIIT Hyderabad, India.

The Hindi Universal Dependency Treebank was automatically converted from Hindi Dependency Treebank (HDTB) which is part of an ongoing effort of creating multi-layered treebanks for Hindi and Urdu. HDTB is developed at IIIT-H India.

The project is supported by NSF Grant (Award Number: CNS 0751202; CFDA Number: 47.070).
