Goodreads, a social network that lets readers rate and review books, has launched a recommendation engine designed to help users choose what to read next.
The new feature comes six months after the startup acquired Discovereads, a book recommendation engine which is something CEO Otis Chandler cited as a sought-after feature among Goodreads users.
The site's new reading recommendations are generated using a set of propriety algorithms which look at over 20 billion different data points. Perhaps most importantly, it takes into account the stated preferences of of its nearly 6 million users, for whom rating books is already a key component of using the site.
... The site's book recommendations are heavily influenced by each user's book rating history, so people are encouraged to rate 20 books before checking out their suggested reading list. The service is now available in beta to all Goodreads users.
