Over 39 million topics and a billion facts have been uploaded to Freebase, a community-curated database of well-known people, places, and things. Imagine being able to access information via simple queries using Metaweb Query Language (MQL). That's Freebase! Freebase is even powering some applications – supplying the topics that apps like Swipp are utilizing to organize and rate topics. Special thanks to Chris Carfi for sharing the technology with me!
Via Wikipedia: Freebase is a large collaborative knowledge base consisting of metadata composed mainly by its community members. It is an online collection of structured data harvested from many sources, including individual ‘wiki' contributions. Freebase aims to create a global resource which allows people (and machines) to access common information more effectively. It was developed by the American software company Metaweb and has been running publicly since March 2007. Metaweb was acquired by Google in a private sale announced July 16, 2010.
MQL is a JSON style query format that can produce some very finite results:
There are often times, as marketers, where we're doing research on topics, related topics, and identifying the hierarchy and relationship between elements. Freebase may come in handy for this type of work. Freebase even has a suggestion widget to help you autosuggest people places or things within your forms. For instance, perhaps you want to select a company within a specific city, or a list of books on a specific topic, or even celebrities or musicians by project type… Freebase can respond with the data you need.
