SynthBio: A Case Study in Human-AI Collaborative Curation of Text Datasets
This addresses the need for higher-quality datasets in NLP research, though it is incremental as it builds on existing dataset curation approaches.
The paper tackled the problem of noisy and biased text datasets in NLP by introducing a human-AI collaborative curation method, resulting in SynthBio, a less noisy and more balanced evaluation set compared to WikiBio.
NLP researchers need more, higher-quality text datasets. Human-labeled datasets are expensive to collect, while datasets collected via automatic retrieval from the web such as WikiBio are noisy and can include undesired biases. Moreover, data sourced from the web is often included in datasets used to pretrain models, leading to inadvertent cross-contamination of training and test sets. In this work we introduce a novel method for efficient dataset curation: we use a large language model to provide seed generations to human raters, thereby changing dataset authoring from a writing task to an editing task. We use our method to curate SynthBio - a new evaluation set for WikiBio - composed of structured attribute lists describing fictional individuals, mapped to natural language biographies. We show that our dataset of fictional biographies is less noisy than WikiBio, and also more balanced with respect to gender and nationality.
