Imagine a commerce world where thematic and seasonal stores could automatically pop up and then disappear with minimal editorial work. Here we talk about the underlying platform that enables mining large-scale user behavior and query data to set up stores automatically based on themes of interest, and emerging and buzz-creating topics. We will describe the science and tools to build experiences that would drive commerce through custom experience and social media, and help sellers, shoppers, and the enthusiasts.
