Everything is Connected (http://everythingisconnected.be) is a Linked Data application for automatically generating a story between two concepts in the Web of Data, based on formally described links. A path between two concepts is obtained by browsing linked open datasets; the path is then enriched with multimedia presentation material for each node in order to obtain a full multimedia presentation of the found path. An efficient technique combining pre-processing and indexing of RDF datasets is used, which is able to find paths in a couple of seconds.

of Linking Pages we Link

semantically so Generic
intelligent agents can
UNDERSTAND and BROWSE
