Empirical Error Modeling Improves Robustness of Noisy Neural Sequence Labeling (2021.findings-acl)
Copied to clipboard
| Challenge: | Standard sequence labeling systems fail when processing noisy user-generated text or consuming the output of an OCR process. |
| Approach: | They propose an empirical error generation approach that employs a sequence-to-sequence model trained to perform translation from error-free to erroneous text. |
| Outcome: | The proposed method outperforms baseline noise generation and error correction techniques on the erroneous sequence labeling data sets. |
NAT: Noise-Aware Training for Robust Neural Sequence Labeling (2020.acl-main)
Copied to clipboard
| Challenge: | Sequence labeling systems should perform reliably under ideal conditions and with corrupted inputs. |
| Approach: | They propose two noise-aware training objectives that improve robustness of sequence labeling performed on perturbed inputs. |
| Outcome: | The proposed methods improve robustness on English and German named entity recognition benchmarks. |
