Yahoo! PlaceFinder and PlaceSpotter are two addtions to the BOSS family of API products. Below you will find the updated descriptions of the two features and how to use them to create a richer experience for your users.
Yahoo! PlaceFinder is a RESTful Web service that supports world-wide geocoding of street addresses, points of interest (POI), airports, and place names. The service also supports world wide reverse geocoding of latitude/longitudes to addresses.
PlaceFinder supports POI's such as schools, shopping malls, museums, and transit stations. Supported place names include counties, states, countries, and continents.
To access the PlaceFinder Web service, call HTTP GET on the base URI, specifying the input location with one or more URI parameters. The response from PlaceFinder contains geographic data, including latitude and longitude, as well as address information such as street, state, and country. (See Examples.)
PlaceFinder supports the following type of queries:
Yahoo! PlaceSpotter is a geoparsing web service that provides third-party developers the means to "geo-enrich" content at scale. The service identifies, "disambiguates" the data, and "extracts" places from unstructured and structured textual content: web pages, RSS (and Atom) feeds, news articles, blog posts, ad tiles and creatives, and status updates. It is an open API that assists developers in creating local and location aware applications and datasets. PlaceSpotter is not a geocoder, but rather a geo-enrichment service that assists developers in determining the 'whereness' of unstructured and atomic content, making the Internet more location-aware.
PlaceSpotter recognizes place names in plain text documents and text elements within HTML and XML documents. It also understands geography-rich tags, such as the W3C Basic Geo Vocabulary, and HTML microformats, such as geo and adr (see http://microformats.org/wiki/geo and http://microformats.org/wiki/adr for more information about these microformats).
