Abstract: Recommender systems play an important role in e-commerce. This paper discusses three classical methods - offline analytics, user study, and online experiment - to evaluate the performance of recommender systems and also analyzes their application scenarios. Some performance evaluation metrics of recommender systems are reviewed and summarized from four perspectives (machine learning, information retrieval, human-computer interaction and software engineering) combined with the above three evaluation methods. These evaluation methods and evaluation metrics summarized in the paper provide the designers with guidance for the comprehensive evaluation and selection of recommended algorithms.
