Digital cultural heritage is now a mature field, in which information technologies are used in the service of preserving cultural heritage. The digital form of resources allows for the exploitation of advances in data analytics, semantics, information retrieval, user interaction, profiling and personalization in order to develop new, exciting and stimulating cultural heritage experiences in tourism and education. This special issue aims to form a reference point for the field of personalized delivery of cultural heritage content. We invite works that present and/or review the current state of the art in theory and practice, as well as promising recent advances in the area of aligning the delivery process for cultural heritage content to the needs, goals, characteristics and preferences of individual users and groups of users. The issue is broad in scope, with the caveat that emphasis should be on the link between cultural heritage and personalization techniques; works dealing exclusively with one of the two topics will be deemed out of scope. Topics of interest Semantic modelling for cultural heritage content and their application to personalized content delivery. Advances in knowledge representation. Metadata standards and datasets. Automated reasoning and computational argumentation for personalized explanations and feedback. Personalization/recommendation technologies applied to cultural heritage content. Profiling techniques for individuals, groups and crowds. Context awareness in cultural heritage venues and cities. Applications in cultural, educational or touristic experiences.
