We present an approach to recognise geographical references in multilingual documents and to disambiguate homographic place names. The purpose of this work is to provide users with meta-information about documents (or whole collections) and to present their geographical coverage visually. The approach has been implemented for sixteen languages and is a fully operational part of the online news analysis system NewsExplorer ( and further JRC applications.
