Domain-specific Insight Graph (DIG) is a technology that harvests and harmonizes millions of Web pages to extract key elements of knowledge (e.g., entities and relations). It integrates corporate databases with the extracted data across sources and modalities encoding implicit and purposefully obfuscated relationships. It offers a faceted content search interface and visualizations to support analysis.
