OpenAlex: A fully-open index of scholarly works, authors, venues, institutions, and concepts

Jason Priem, Heather Piwowar, Richard Orr

TL;DR

The resource is under active development and future work will improve accuracy and coverage of citation information and author/institution parsing and deduplication.

Abstract

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.
