報(bào)告內(nèi)容: Recommending the right product at the right time for consumers is the goal of modern online recommendation systems. However, consumers who shop in e-commerce often complain about a phenomenon that the product which you just bought is recommended again. There are two possibilities for this kind of complaint. First, the recommended items do not need to be purchased repeatedly. Second, the recommended item is repurchable, but the recommendation time is not proper. To optimize current recommendation systems and improve consumer’s satisfactions, this paper studies the following problems:

1. Why recommend products that you just purchased?

2. What type of products are prone to repurchase? What type of products are not prone to repurchase?

3. What is an optimal time interval for the recommendation?

4. Can we optimize the current recommendation system so that we can reduce customer complaints while still keep the purchase rate?

To this end, we introduce the consumer-based analysis which has been well studied in the marketing science into the machine-learning-based recommendation systems to handle the above problems.
