To illustrate the structured JSON extraction process, we present one example in Figure , highlighting the transformation of a materials science excerpt into a well-organized JSON file. Additionally, for researchers interested in accessing the annotated data, we have made it publicly available on Figshare, offering a valuable resource for further scientific analysis. This dataset serves as a testament to the precision and clarity embedded in our semi-automated annotation approach, showcasing its potential for efficient text annotation in the materials science domain.
