Abstract

Case retrieval for e-commerce product recommendation is an application of CBR that demands particular attention to efficient implementation. Users expect quick response times from on-line catalogs, regardless of the underlying technology. In FindMe systems research, the cost of metric application has been a primary impediment to efficient retrieval. This paper describes several types of general and special-purpose ranking algorithms for case retrieval and evaluates their impact on retrieval efficiency with the Entree restaurant recommender.
