Over the body of a corpus, if a name n is often given a high confidence of referring to a point p, then the likelihood that n refers to p is high even in the absence of other evidence in the document.
For any context C, an adjustment is applied to the confidence which is a nonlinear function of the probability of a geographic reference occurring in C in the tagged corpus.
If the system determines that Portland refers to Portland, Oregon with confidence c, then we assume that 15 miles northeast of Portland refers to the point 15 miles northeast of Portland, Oregon with confidence f(c), where f(c) is greater than c, since the presence of a well-defined relative reference serves as an additional linguistic clue.

This relative reference is resolved in correspondence with the resolution of its anchor reference, Portland.
Much of the geographic and demographic information for the U.S. states, counties, and cities came from the data on the site.
The data contain information on a wide range of geographic features such as populated places, rivers, mountains, certain buildings, etc. The data provided include geographic coordinates, elevation at the point, population (if applicable), and the FIPS codes for the state and county containing the feature (but not the feature itself).

 Georeferencing in Digital Libraries
Georeferencing is relating information (e.g., documents, datasets, maps, images, biographical information, artifacts, specimens) to geographic locations through placenames (i.e., toponyms) and place codes (e.g., postal codes) or through geospatial referencing (e.g., longitude and latitude coordinates).
In May 2003, a workshop on Analysis of Geographic References was held as part of the North American Chapter of the Association for Computational Linguistics and Human Language Technology Conference (NAACL-HLT 2003) in Edmonton, Alberta (Kornai and Sundheim, 2003).

 Geographic Information Retrieval and Spatial Browsing   (Site not responding. Last check: 2007-11-06)
Geographic Information Retrieval, as we define it here, is an applied research area that combines aspects of DBMS research, User Interface Research, GIS research, and Information Retrieval research, and is concerned with indexing, searching, retrieving and browsing of geo-referenced information sources, and the design of systems to accomplish these tasks effectively and efficiently.
Geographic querying assumes that the space is delineated by the well-defined coordinate systems of the "real world." In the following discussion, the emphasis will be on geographic querying, although the underlying implementation might be a general purpose spatial database system rather than a geographic information system.
In traditional library cataloging practice, geographic references have been a common form of access point assigned to documents (primarily books and maps), but assignment was based on the cataloger's notion of whether geographic identification was deemed important for access to the document.

 How GIS Work   (Site not responding. Last check: 2007-11-06)
Geographic information contains either an explicit geographic reference, such as a latitude and longitude or national grid coordinate, or an implicit reference such as an address, postal code, census tract name, forest stand identifier, or road name.
An automated process called geocoding is used to create explicit geographic references (multiple locations) from implicit references (descriptions such as addresses).
These geographic references allow you to locate features, such as a business or forest stand, and events, such as an earthquake, on the earth's surface for analysis.

either an explicit geographic reference such as a latitude and longitude or national grid coordinate, or an implicit reference such as an address, postal code, census tract name, forest stand identifier, or road name.
Implicit references can be derived from explicit references using an automated process called "geocoding." These geographic references allow you to locate features (like a business or forest stand) and events (like a chemical spill) on the surface of the earth for analysis.
Both the vector and raster models for storing geographic data have unique advantages and disadvantages and modern GISs are able to use both in concert to effectively perform the most complex analysis tasks.
