determining a user interest on the e-commerce website in a first product;

generating at least one product recommendation for the user based on the product recommendation data and the user interest on the e-commerce website in the first product; and

creating the list of product recommendations based on the generated at least one product recommendation and the user interest on the e-commerce website in the first product; and

displaying at least one product recommendation from the list of product recommendations on a remote computer on a webpage for a user who indicated the user interest in the first product,

wherein the user preference data include a product matrix generated using collaborative filtering, and

wherein the product attribute data comprise a product attribute matrix generated by correlating product attributes between products.

10. The method of claim 9 , wherein the user interactions comprise one of clicks and views.
