What data is stored in Watson?
All of Watson’s data will be self-contained. Watson will perform without a connection to the web or any external resource. The vast majority of Watson’s data will be a wide variety of natural language text. Some structured (formal knowledgebase’s) and semi-structured data (tagged text) is also included mostly to help interpret text and refine answers. Exactly which data will be used for competing on Jeopardy! will be revealed at a later date, but the specific content and how to analyze and manage it are part of the research agenda.
