HERITRACE: enabling domain expert participation in semantic data curation with integrated provenance and change tracking - PhD defence presentation

Presentation slides for the PhD defence of Arcangelo Massari, joint programme between the University of Bologna and KU Leuven. The presentation covers the design, implementation, and evaluation of HERITRACE, a web-based system that enables domain experts in cultural heritage institutions to curate RDF data without requiring technical expertise, while maintaining provenance documentation and change tracking. The presentation addresses two research questions: how to design interfaces for domain experts to perform daily semantic data curation, and how technical staff can configure the system for specialised domains. It includes a comparative evaluation of existing semantic data management systems (OmekaS, CLEF, ResearchSpace, Semantic MediaWiki, Wikibase), the provenance representation model based on the OpenCitations Data Model and PROV-O, the Time-Agnostic Library for temporal queries, two case studies (OpenCitations Meta and ParaText), a mixed-methods usability evaluation with 19 participants, and preliminary work on RML mapping inversion for extending HERITRACE to non-RDF data sources.
