Unlock Text is a powerful geoparser that can search text hosted on the web in txt or html format for references to locations. These locations are then returned ready for use in your results page, web map or any other application.
The Unlock Text API provides access to two parsers, the Edinburgh Geoparser from the Edinburgh Language Technology Group and the CLAVIN parser.
