"A simple RESTful web service. POST your text content – either plain text, or HTML pages or XML containing metadata – and get back a feed of the named places found in the text, with best guesses as to their locations.
First, we extract likely placenames from a piece of text. Next, we look up the placenames in the gazetteer, and match the placenames to locations using the context provided by the text. For example, if "Leith" and "Portobello" are mentioned together, we're more likely to be talking about "Leith, Edinburgh" than "Leith, Ontario"."
