On the Robustness of Cognate Generation Models
Proceedings of the Thirteenth International Conference on Language Resources and Evaluation (LREC 2022)
Abstract
We evaluate two popular neural cognate generation models’ robustness to several types of human-plausible noise (deletion, duplication, swapping, and keyboard errors, as well as a new type of error, phonological errors). We find that duplication and phonological substitution is least harmful, while the other types of errors are harmful. We present an in-depth analysis of the models’ results with respect to each error type to explain how and why these models perform as they do.
