Once downloaded, synthesis paragraphs were identified using ChemDataExtractor2.1 according to previously developed protocols for identifying MOF synthesis methods. In this procedure, chemical named entity recognition was performed using BERT to identify potential reagents, and part-of-speech (POS) tagging was carried out on the remaining tokens to interpret sentence grammar. Chemical quantities were identified from the POS tags as CD-NN bigrams (phrases consisting of a cardinal number followed by a noun), and regex matching of the noun against a library of SI units. Synthesis paragraphs were identified as containing three or more chemical named entities and three or more chemical quantities, after which each paragraph was extracted as plain text for manual confirmation and later analysis.
