Placemaker is a Yahoo! API that analyzes text documents and extracts references to places, people, brands and events. It returns this information along with related metadata in JSON or XML format. The document discusses how to use the Placemaker API, parameters for the API call, working with the results, and several examples of how Placemaker has been implemented in web applications and browser extensions to associate text with locations.
