An enhanced recommendation scheme for online grocery shopping

Online grocery shopping becomes more and more popular in recent years. To facilitate the purchase process, many online stores provide a shopping recommendation system for their consumers. So far, the generic recommendation systems mainly consider preferences of a consumer based on his/her purchase histories. Nevertheless, it is noted that there is nothing to do with the right timing to purchase a product from the view point of product replenishment or economic purchasing. Hence, we develop a new recommendation scheme especially for online grocery shopping by incorporating two additional considerations, i.e., product replenishment and product promotion. We believe that such a new scheme should be able to provide a better recommendation list which fit consumer desires, needs, and budget considerations and finally boost transactions.
