We’ve published [a new version of the dataset of relationships between preprints and journal articles](https://doi.org/10.5281/zenodo.15124417) 🎉 The dataset is a result of applying [the preprint matching strategy](https://gitlab.com/crossref/labs/marple/-/blob/main/strategies_available/preprint_sbmv/strategy.py) at scale to the metadata deposited by Crossref members. The dataset contains both relationships asserted by Crossref members and matched by the strategy. The dataset is a single CSV file with the following fields: - preprint DOI (string) - journal article DOI (string) - whether the publisher of the journal article deposited this relationship (boolean) - whether the publisher of the preprint deposited this relationship (boolean) - the confidence score returned by the matching strategy (float, empty if the strategy did not discover this relationship) The dataset contains: - 1,060,572 relationships in total, including 954,782 preprints and 953,453 journal articles, - 24,333 of the relationships were deposited by the Crossref members, but not discovered by the strategy, - 598,480 of the relationships were discovered by the strategy, but not provided by any Crossref member, - 437,759 of the relationships were both deposited by a Crossref member and discovered by the strategy. More information about the matching approach and strategy can be found [here](https://doi.org/10.64000/dpcc9-k4564).
