MediaCampaign's scope is on discovering and inter-relating advertisements and campaigns, i.e. to relate advertisements semantically belonging together, across different countries and different media. The project's main goal is to automate to a large degree the detection and tracking of advertisement campaigns on television, Internet and in the press. For this purpose we introduce a first prototype of a fully integrated semantic analysis system based on an ontology which automatically detects new creatives and campaigns by utilizing a multimodal analysis system and a framework for the resolution of semantic identity. ©2008 IEEE.
