Machine learning research output by country and year (works count)

Annual counts of scholarly works tagged with the OpenAlex 'Machine learning' concept (C119857082), by author country and publication year. Provenance: OpenAlex Works API (https://api.openalex.org/works), keyless, CC0-1.0. Counts include all work types OpenAlex indexes (journal articles, preprints, conference papers, datasets); a work with authors in several countries counts once per country. Coverage: publication years 2015 to the present; years before 2015 are not collected. Kosovo appears under the de facto code XKX (ISO 3166-1 assigns it no code). Primary key: (country_code, year); country_code is ISO 3166-1 alpha-3 and joins other hub country datasets. Cadence: refreshed monthly; the current year is partial and its counts grow as OpenAlex indexes new works. Nullability: works_count is never null (0 allowed); country_code, country_name and year are never null. Sample use: filter year = the latest full year and order by works_count desc for the current country ranking.
