Much of the information available in digital libraries and on the Internet is georeferenced, although mostly it is not denoted in terms of geographic coordinates. Often, the link(s) between the information in a textual document and the location(s) it refers to manifests itself as place names and/or phrases that suggest a geographic location and. The geographic location and extension of a place name is often called a geographic footprint [14] and is given by coordinates (latitude, longitude). Geographic Information Retrieval requires that place names and phrases that include direct or indirect references to place names be resolved and translated into footprints that can be indexed. There are, however, some problems using place names and phrases that contain place names for assigning footprints to
documents that uniquely identifies a location for the document.
