ACAI Dataset — Archive of Contemporary Art Event Information (South Korea)

ACAI is a relational dataset of contemporary-art events in South Korea, built from the public websites of three national/municipal institutions — the National Museum of Modern and Contemporary Art (MMCA), the Seoul Museum of Art (SeMA) and the Asia Culture Center (ACC) — plus the national open-call portal Artnuri, from 2000 to 2025. It covers 1,775 exhibitions, 6,250 public programs (education 4,305, culture 1,945), 5,490 open calls and 17,929 collection works (MMCA 11,762, SeMA 6,167), resolved to 9,759 participants, 1,892 organizations and 698 venues, and indexed with 5,505 thematic keywords (27,073 event–keyword assignments) mapped onto 2,277 theme categories — 1,848 Getty AAT concepts, 428 local categories, and one residual category for unmatched low-frequency keywords.

 

The keyword layer was rebuilt end to end. Keywords were re-extracted from all exhibition and program descriptions under a formalized contract with verbatim text evidence and machine validation gates; surface variants were merged through deterministic normalization plus a fully logged human review. Matching to the Getty AAT was redesigned as a retrieval-then-verify procedure over the full five AAT facets (49,105 candidate concepts), decided once per keyword with an exact/close/broad/no-match verdict. Accordingly, the theme category and match quality now live on the keyword table rather than on event_keyword (schema change). In addition, 417 truncated or caption-only description texts were repaired against the live source pages, and all theme categories now carry Korean labels.
