Open Source and Datasets

IteraTeR (2022), R3 (2022), DELIteraTeR (2022): Iterative Text Revision (IteraTeR) From Human-Written Text.

Pseudonymization (2023): This work investigates the effectiveness of different pseudonymization techniques, ranging from rule-based substitutions to using pretrained large language models on a variety of datasets and models used for two widely used NLP tasks: text classification and summarization.

Grammarly NLP researchers found evidence of bias in off-the-shelf grammatical error correction systems: they performed worse for sentences with the gender-neutral pronoun “They.” So, we developed a technique to create augmented datasets with many examples of the singular “they.” We hope others use it to make NLP systems more gender-inclusive.

GECToR: Grammatical Error Correction: Tag, Not Rewrite. The GitHub repository provides code for training and testing state-of-the-art models for grammatical error correction with the official PyTorch implementation of the paper titled “GECToR: Grammatical Error Correction: Tag, Not Rewrite.”
