FLORES+ Extended with Three Mozambican Bantu Language Evaluation Sets
Researchers added Portuguese-source evaluation data for Xichangana, Mozambican Nyanja, and Sena to the FLORES+ multilingual benchmark. The work examines how conflating closely related language varieties affects machine translation evaluation, comparing Xichangana against Tsonga and Mozambican Nyanja against Chichewa. It argues that merging distinct varieties into a single reference can distort measured translation quality.
