The document discusses emerging technologies that will drive the next e-commerce revolution: big data, personalization using fashion profiles, small data from wearable devices, agile platforms for small retailers, and the semantic web. It provides examples like Dressipi using data to accurately predict best-selling items, Jawbone helping users change behaviors using precise data at the right time, and Tictail giving small retailers powerful e-commerce tools. The implication is that existing industry advantages may be swept away if companies can't make sense of growing data and the semantic web shifts where online information power sits. Retailers are challenged to assess if their current business has a defensible advantage in this changing environment.
