Yahoo! Placemaker is a freely available geoparsing Web service. It helps developers make their applications location-aware by identifying places in unstructured and atomic content – feeds, web pages, news, status updates – and returning geographic metadata for geographic indexing and markup.

The Yahoo! Query Language lets you query, filter, and join data across any web data source or service on the web. Using our YQL web service, apps run faster with fewer lines of code and a smaller network footprint. YQL uses a SQL-like language because it is a familiar and intuitive method for developers to access data. YQL treats the entire web as a source of table data, enabling developers to select * from Internet.
