About ThoughtSource⚡
ThoughtSource is a central, open resource and community centered on data and tools for chain-of-thought (CoT) reasoning in large language models. Developed by the Samwald research group, it provides standardized datasets, dataloaders, and a dataset annotator to support trustworthy and robust reasoning in AI systems, particularly for scientific and medical question answering. The project includes reasoning chains from multiple sources (human-generated, AI few-shot, AI zero-shot) and uses the Hugging Face Datasets format for easy integration.
Key Features
Curated chain-of-thought datasets from multiple sources (human-generated, AI few-shot, AI zero-shot)
Standardized dataloaders in Hugging Face Datasets format
Tutorial notebook and dataset annotator included
Supports general and scientific/medical question answering (CommonsenseQA, StrategyQA, WorldTree, EntailmentBank, etc.)
Open source and community-driven development
