About the Project
What is Starrydata
Starrydata is an open data project that extracts and structures experimental data from graphs in inorganic materials science papers, making them freely reusable for researchers worldwide.
Founded at NIMS in 2017, Starrydata is now operated by a dedicated research team in collaboration with RIKEN AIP, the University of Tsukuba and others. High-quality experimental data — useful for Materials Informatics, machine learning, and new-material discovery — are freely available via API, Figshare, and GitHub.
Massive Dataset
A large-scale database
104,823 samples and 233,061 curves from 13,000+ papers. Numerical data carefully extracted from plots in literature, ready for machine learning and data analysis.
