The term "recommender systems" evolved to replace and
broaden the use of the term "collaborative filtering" because
the latter term refers to a specific algorithm for recommending.
The term “recommender system” refers both to systems that specifically
recommend lists of products and to those that help users evaluate
products. Previously, these systems were distinguished as systems
that provide "recommendations," those that provide
"predictions" of user preference, and those that provide
"community
opinion." The
recommender systems research community has embraced all three
components.
In this paper, Schafer et al. surveyed the recommender applications
used by several of the largest E-commerce companies. Several design
parameters were identified and a taxonomy that classifies these
applications by their inputs, output, recommendation method, degree of
personalization, and delivery method was developed. Classifying the
applications revealed a set of application models that reflect the state
of practice. Promising directions in recommender systems have also
explored, including application ideas built on innovative models that
transcend current practice.
Technologists often assume that the "best" recommender
application is one that is fully automatic and completely
invisible. The study in this paper does not bear this assumption
out at all. Many different recommender models were found, each of
which is appropriate for a different set of business goals. Each of
these models addresses different business needs that reflect different
business models, customers, and marketing plans. By selecting the
appropriate combination of recommender applications, businesses can
maintain their competitive advantage, retain customers, and increase
sales.
