Abstract EN
Recommender systems are used to make recommendations about products, information, or services for users.
Most existing recommender systems implicitly assume one particular type of user behavior.
However, they seldom consider user-recommender interactive scenarios in real-world environments.
In this paper, we propose a hybrid recommender system based on user-recommender interaction and evaluate its performance with recall and diversity metrics.
First, we define the user-recommender interaction.
The recommender system accepts user request, recommends N items to the user, and records user choice.
If some of these items favor the user, she will select one to browse and continue to use recommender system, until none of the recommended items favors her.
Second, we propose a hybrid recommender system combining random and k-nearest neighbor algorithms.
Third, we redefine the recall and diversity metrics based on the new scenario to evaluate the recommender system.
Experiments results on the well-known MovieLens dataset show that the hybrid algorithm is more effective than nonhybrid ones.
