When recommender applications provide identical recommendations to each customer, the application is classified as non- personalized. The specific recommendations may be based on manual selection, statistical summarization, or other techniques. Many of the E-commerce recommendation examples are non-personalized. Top-sellers, editor choices, average ratings, and unfiltered customer comments all present the same recommendations to each customer of the system.
Recommenders that use current customer inputs to customize the recommendation to the customer’s current interests provide ephemeral personalization. This is a step above non-personalized recommenders because it provides recommendations that are responsive to the customer's navigation and selection. Particular implementations may be more or less personal, however. A recommender application with a high degree of ephemeral personalization would be one that uses an entire current browsing session or shopping cart to recommend items. Conversely, a recommender application that simply attaches recommendations to the current item is nearly non-personalized. Ephemeral personalization is usually based on item-to-item correlation, attribute-based recommendation, or both. Examples of ephemeral personalization include CDNOW's multi-item Album Advisor and certain versions of Drugstore.com’s Advisors. Both take information provided by the customer at recommendation time and return a list of suggestions from that ephemeral context.
The most highly-personalized recommender applications use persistent personalization to create recommendations that differ for different customers, even when they are looking at the same items. These persistent recommenders employ user-to-user correlation, attribute-based recommendation using persistent attribute preferences, or item-to-item correlation based on persistent item preferences. They require customers to maintain persistent identities, but reward them with the greatest level of personal recommendation. Examples of persistent personalization include My CDNOW, which uses user-to-user correlation, and Amazon.com's Eyes and eBay's Personal Shopper, which use persistent attribute recommendation.
