I am currently working on this problem with one client. We are doing different sorts of market analysis, by analyzing products. In particular, we are looking at optimizing profits by choosing product titles more effectively, as well as optimizing profit by choosing price points more effectively. This can be used purely automatically, as black box decisions, or this information can be presented in a visualization interface for a human analyst. We've also talked about several other ways of turning historical sales data into actionable business intelligence. One thing we haven't looked at is doing market analysis based upon customer profiles. This is an interesting idea, and I have some thoughts on how to do it. Essentially, finding different ways to cluster users, and then "explaining" who these customer segments. The explainability is based upon figuring out the most important features they have in common, and exposing these features in plain English.
