DIVE+: Explorative Search for Digital Humanities

685 views

Published on

DIVE+ is an event-centric linked data digital collection browser aimed to provide an integrated and interactive access to multimedia objects from various heterogeneous online collections. It enriches the structured metadata of online collections with linked open data vocabularies with focus on events, people, locations and concepts that are depicted or associated with particular collection objects. DIVE+ is result of a true inter-disciplinary collaboration between computer scientists, humanities scholars, cultural heritage professionals and interaction designers. The tool allows humanities scholars to explore unexpected relations between entities and media objects and to construct and share navigation paths to develop research narratives.
