Figure 2
This figure illustrates the processing of the raw metadata pulled from the ESRF data ecosystem. The Titles are joined to form a singular Title. GROBID was used to process the experiment reports into structured texts and citation information. These structured texts are combined with the Abstracts to form the Abstract. The same was done with the Scientific Disciplines, which were used as a proxy for `Journal name'. The references extracted using GROBID include the DOIs, allowing them to be linked to their OpenAlex IDs via the OpenAlex repository. This gave the Citations. Similarly, the publications were mapped to their OpenAlex IDs via DOIs, resulting in the collective Publications. The dashed squares represent unique identifiers that link the various elements. The Title, Abstract, Citations, `Journal name', and/or Publications were the inputs to the OpenAlex model for topic classification of the proposals.
