A morpheme-based treebank for Gbaya, an Ubanguian language of Central Africa

Paulette Roulon-Doko, Sylvain Kahane, Bruno Guillaume


Abstract
In this paper, we present the first treebank for Gbaya, a language from the under-resourced Niger-Congo family. The language has a rich system of tonal morphemes and virtually no affixes. The dependency analysis is based on a morpheme-based tokenisation and the treebank is also distributed in word-based Universal Dependencies version. Several constructions are discussed in the paper: genitive construction, clause coordination, sentence particles, adverbial and relative clauses, serial verb constructions, reported speech, topicalization, and focalization.
