It has prominent impacts in e-commercerelated applications by facilitating users' experience in online platforms and supporting business organizations' decision-making. Among all the techniques and applications, user profiling and recommender systems are two representative and effective ones, which have also obtained growing attention. In view of its wide applications, researchers and practitioners should improve user modeling from two perspectives: (1) more effort should be devoted to obtain more user data via techniques like sensing devices and develop more effective ways to manage complex data; and (2) improving the ability of learning from a limited number of data samples (e.g., few-shot learning) has become an increasingly hot topic for researchers.enginfo:eu-repo/semantics/restrictedAccessArticle4000052894360003410.1016/j.elerap.2020.100955Data managementFew-shot learningLearning with limited dataRecommender systemsUser modelingUser profilingUser profiling2-s2.0-85079555814
