This week marks the fifteenth annual International Open Access Week. Since 2010, the week has provided a platform to discuss the state and challenges of open access to scientific knowledge. While the early years focused on access to scientific articles (“Open Access Week” 2024), this year’s activities increasingly address other aspects of Open Science.
OpenAlex is a new, fully-open scientific knowledge graph (SKG), launched to replace the discontinued Microsoft Academic Graph (MAG). It contains metadata for 209M works (journal articles, books, etc); 2013M disambiguated authors; 124k venues (places that host works, such as journals and online repositories); 109k institutions; and 65k Wikidata concepts (linked to works via an automated hierarchical multi-tag classifier). The dataset is fully and freely available via a web-based GUI, a full data dump, and high-volume REST API. The resource is under active development and future work will improve accuracy and coverage of citation information and author/institution parsing and deduplication.
