Enriching Cultural Heritage through Semantic Annotation: A Review of Methods, Tools, and Collaborative Spaces

This paper presents a comprehensive review of semantic annotation practices applied within the digital humanities (DH) domain. As the demand for enriched, interoperable cultural data increases, semantic annotation and Linked Open Data (LOD) have emerged as key technologies in preserving and connecting heritage materials across digital platforms. This study examines current methodologies, tools, and frameworks for annotation systems, emphasizing the productive aspects involved in leveraging annotations on research environments. We developed a multidimensional classification schema to assess annotation systems, along with a critical overview of semantic annotation in DH. The paper concludes with recommendations for future research.
