This document discusses how unlocking insights from "dark data" can provide competitive advantages. It notes that only a small fraction of available data is currently used and that cognitive technologies are needed to unlock the potential in all data, including unstructured data sources like social media, IoT sensors, images and video. Specifically, it describes how visual insights from photos and video can provide customer segmentation insights and how combining diverse data sources like transactions, interactions and external events can provide a more complete understanding of customers.
