Humboldt: Exploring Linked Data

Kobilarov, Georgi; Dickinson, Ian


Keyword(s): user interface, semantic web, facet browsing, RDF, linked data

Abstract: We present Humboldt, a novel user interface for browsing RDF data. Current user interfaces for browsing RDF data are reviewed. We argue that browsing tasks require both a facet browser's ability to select and process groups of resources at a time and a 'resource at a time' browser's ability to navigate anywhere in a dataset. We describe Humboldt which combines these two features in a single coherent interface. Our approach is based on the operation of pivoting, which enables the user to move the focus of a browsing from one set of resources to a set of related resources. With repeated use of the pivot operation the user can browse anywhere in the data. We describe a preliminary evaluation of our approach and discuss its implications for further development.
