This provides (art-)historians and Cultural Heritage professionals with a wealth of information to explore. Specifically, structured data about iconographical and iconological (<jats:italic>icon<\/jats:italic>) aspects, i.e. information about the subjects, concepts and meanings of artworks, are extremely valuable for the state-of-the-art of computational tools, e.g. content recognition through computer vision. Nevertheless, a data quality evaluation for art domains, fundamental for data reuse, is still missing. The purpose of this study is filling this gap with an overview of art-historical data quality in current KGs with a focus on the icon aspects.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title><jats:p>This study\u2019s analyses are based on established KG evaluation methodologies, adapted to the domain by addressing requirements from art historians\u2019 theories. The authors first select several KGs according to Semantic Web principles. Then, the authors evaluate (1) their structures\u2019 suitability to describe <jats:italic>icon<\/jats:italic> information through quantitative and qualitative assessment and (2) their content, qualitatively assessed in terms of correctness and completeness.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Findings<\/jats:title><jats:p>This study\u2019s results reveal several issues on the current expression of <jats:italic>icon<\/jats:italic> information in KGs. The content evaluation shows that these domain-specific statements are generally correct but often not complete. The incompleteness is confirmed by the structure evaluation, which highlights the unsuitability of the KG schemas to describe <jats:italic>icon<\/jats:italic> information with the required granularity.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>The main contribution of this work is an overview of the actual landscape of the <jats:italic>icon<\/jats:italic> information expressed in LOD. Therefore, it is valuable to cultural institutions by providing them a first domain-specific data quality evaluation. Since this study\u2019s results suggest that the selected domain information is underrepresented in Semantic Web datasets, the authors highlight the need for the creation and fostering of such information to provide a more thorough art-historical dimension to LOD.<\/jats:p><\/jats:sec>","DOI":"10.1108\/jd-09-2022-0207","type":"journal-article","created":{"date-parts":[[2023,4,10]],"date-time":"2023-04-10T08:05:00Z","timestamp":1681113900000},"page":"115-136","source":"Crossref","is-referenced-by-count":10,"title":["Is dc:subject enough?
