Abstract: A method for recommending an item includes generating a metadata latent vector and an item latent vector based on an item database and a usage history database of items for a specific user; predicting a user latent vector from user information obtained from the specific user based on the usage history database and one of the metadata latent vector and the item latent vector; and generating a recommendation list by extracting at least one recommendation item from the item database based on the user latent vector and the item latent vector.
