“…Some of them focus on specific fields (like cultural heritage). There is no study yet that evaluates specific aspects related to iconology and iconography in KGs, which would require a specific evaluation due to the complexity of the information expressed by this domain of knowledge (Baroncini et al ., 2021; Sartini et al ., 2021). Therefore, the contribution of the current paper is to adapt a selection of the general metrics from the literature to the domain-specific needs, with the addition of a newly created metric.…”

PurposeIn the last few years, the size of Linked Open Data (LOD) describing artworks, in general or domain-specific Knowledge Graphs (KGs), is gradually increasing. This provides (art-)historians and Cultural Heritage professionals with a wealth of information to explore. Specifically, structured data about iconographical and iconological (icon) 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.Design/methodology/approachThis study’s analyses are based on established KG evaluation methodologies, adapted to the domain by addressing requirements from art historians’ theories. The authors first select several KGs according to Semantic Web principles. Then, the authors evaluate (1) their structures’ suitability to describe icon information through quantitative and qualitative assessment and (2) their content, qualitatively assessed in terms of correctness and completeness.FindingsThis study’s results reveal several issues on the current expression of icon 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 icon information with the required granularity.Originality/valueThe main contribution of this work is an overview of the actual landscape of the icon information expressed in LOD. Therefore, it is valuable to cultural institutions by providing them a first domain-specific data quality evaluation. Since this study’s 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.

“…Another problem is the lack of advanced ontologies [2] that provide a detailed semantic form to artwork description data. Only recently, a few ontologies have been designed to express icon features (Carboni and de Luca, 2019) and cultural symbolism (Sartini et al ., 2021), opening the possibility to extract and represent KGs as required.…”
