0.63% increase in the number of research products (+1.9Mi)

0.29% increase (+324K) in the number of research products with affiliation information

Fixed the use of titles blacklist in the deduplication of research products. In the previous version, the titles blacklist was not used in the deduplication process, leading to a higher number of duplicates. The deduplication process now uses the titles blacklist to identify and remove duplicates more effectively. However, the scope of this change is limited due to the relatively small number of records in the titles blacklist, currently between 200 and 300.

Added an extended set of inferred RAIDs consisting of ~30K records, grouping under the same research activity publications, projects and organizations.

Introduced a blacklisting mechanism to remove research products that are withdrawn from Zenodo. The blacklist today contains 1.2Mi DOIs that, starting from this release, will be systematically removed from the Graph. As these records might have relations with other entities, the relations will be removed as well. In the context of this update we do observe a decrease of ~5% (254K) in the number of research products related to a project, the majority of them being related to the withdrawn DOIs.
