Method

MPIE tool allows any researcher to extract material property information from a large scientific corpus of copyright-protected journal manuscripts. No coding skills or NLP knowledge needed.

What

• MPIE (Materials Property Information Extractor) web tool was developed to extract functional property information from a corpus of full-text scientific articles about crystalline materials.
• Currently, MPIE focuses on perovskite structures and operates on a corpus of 192,694 articles on all perovskite materials gathered from various publishers, including Springer, Elsevier, and arXiv.
Note: The dataset is not available for download due to not being fully open access.

How

• MPIE uses simple human language queries of the type "What is the numerical value of the property Y for material X". The user only needs to supply information about the material (X) and property (Y), with the unit as optional.
• By default, MPIE relies on BERT-based Question Answering (QA) tools for information extraction (QA MatSciBERT), with new tools coming soon.
• The user obtains a statistical distribution of values from the literature and a list of source manuscript DOIs to facilitate retrieval.
