tFacet logo Hierarchical Faceted Exploration of RDF Data

tFacet applies known interaction concepts to allow hierarchical faceted exploration of RDF data. The aim is to facilitate ordinary users to formulate semantically unambiguous queries so as to support the fast and precise access to information. Used interaction concepts are e.g. a directory tree and interchangeable columns that are already well-known from other applications. The directory tree, for example, is used to enable the intuitive exploration and selection of hierarchical facets. tFacet is based on the open source framework Adobe Flex and uses SPARQL to access RDF datasets.

tFacet is readily configured to access data from the LOD cloud and only requires a Flash Player plugin to be executed (which is usually already installed in web browsers).
