We want to set up a recommendation engine for an e-commerce site. We want this to via a REST API. So all information to and from the recommendation engine will be communicated via REST API.
We'll be using data like, users location, category of product, gender of product, click, purchase, add to cart, wish list etc as the data to generate needed recommendation. You could recommend if anything else is needed.
We where happy with some of prediction.io templates.
