The present invention provides a method used by a user to customize a recommendation
system in an online
system, and belongs to the technical fields of
data mining and
network application. The method aims at a problem that an
algorithm in a previous recommendation
system is fixed and therefore a personalized recommendation system that meets demand of each user cannot be constructed. According to the method, a user customizes a personalized recommendation engine; a policy that a system
algorithm self-adapts to a user is realized; moreover, relatively good recommendation diversity and relatively high recommendation accuracy are ensured; and the time period of a system in learning a user behavior is effectively shortened. The method comprises the following steps: step 1, according to a personal demand, a user starting setting of a recommendation engine in an online system; step 2, via a recommendation
engine configuration page designed by the system, the user setting a recommendation engine parameter to customize a personalized recommendation
algorithm that meets a personal preference of the user; and step 3, storing the configured recommendation engine and applying the configured recommendation engine in a recommendation system, so that according to the recommendation engine parameter set by the user, the system uses a combination policy to form a
hybrid recommendation algorithm through combination, so as to calculate a recommendation
list.
