A Falta de Pan, Buenas Son Tortas: The Efficacy of Predicted UPOS Tags for Low Resource UD Parsing

We evaluate the efficacy of predicted UPOS tags as input features for\ndependency parsers in lower resource settings to evaluate how treebank size\naffects the impact tagging accuracy has on parsing performance. We do this for\nreal low resource universal dependency treebanks, artificially low resource\ndata with varying treebank sizes, and for very small treebanks with varying\namounts of augmented data. We find that predicted UPOS tags are somewhat\nhelpful for low resource treebanks, especially when fewer fully-annotated trees\nare available. We also find that this positive impact diminishes as the amount\nof data increases.\n
