Facebook recently launched its upcoming feature, currently in beta, called Graph Search. The new feature allows anyone to perform a search on Facebook using simple text based queries. It is a unique blend of big data and natural language processing (NLP).
With a billion users under its belly, Facebook is one of the most interesting use cases of how big data evolves with a social graph. Using natural language processing (NLP), Facebook is slowly trying to bring users to a different side of the search world. It works on a highly successful iteration development.
