Based on our labels, we evaluate chatGPT performance in identifying correct extractions. The precision, recall, and F1score obtained were 0.84, 0.96, and 0.90, which are very high scores. Therefore, we decided to keep with our approach and neglected sentences labeled as 0 (i.e., wrong) by chatGPT. Nevertheless, for the particular case of Ag, we notice our regexes capture also relations where "Ag" were extracted from "Ag/AgCl", a reference electrode. Even though we devised in Figure (e), but excluding O-containing materials for a better view. The NaBH composition originates from NaBH 4 , which is a commonly used reducing agent in materials synthesis. We found it quite interesting that this compound appeared in our results, considering that we exclusively analyzed the abstracts of the papers in our corpus. We expected this sort of compound to be present in the methodology section. Once again, we investigated review articles for the applications of this salt, but we did not find any specific mentions of it. Upon examining the extracted sentences, we confirmed that most occurrences referred to the use of NaBH 4 as a reducing agent in materials synthesis. It was interesting to find, however, that this compound has already been directly applied to reduce carbon dioxide, a process called CO 2 hydroboration. It is worth noting that only a few articles mentioned the application of sodium borohydride for this purpose, with the majority of them published between 2014-2016.
