Geographic Information Retrieval and Digital Libraries [PDF]

European Conference on Research and Advanced Technology for Digital Libraries, 2009
In this demonstration we will examine the effectiveness of Geographic Information Retrieval (GIR) methods in digital library interfaces. We will show how various types of information may benefit from explicit geographic search, and where text-based place name search may be sufficient.
