EasyUtil Recommendation web service provides a web API to make recommendations in the format of “people who liked this item also liked those items”.
The service’s engine generates recommendations based on the data a client site provides to the engine. The data is fed into the engine using a “this user likes this item” type of request. The items liked by the same user are considered to be related to each other. This information can be retrieved by using a “people who liked this item also liked which items” kind of request.
