Building Watson: An Overview of the DeepQA Project

Jeopardy also has categories of questions what exactly is being asked for and which elements that require special processing defined by the cate- of the clue are relevant in determining the answer. It Approach to Unstructured Information Processing in the is this team who are responsible for the work Corporate Research Environment. A requirement of the Jeopardy formance of a system based purely on text search, Challenge is that the system be self-contained and using terms in the question as queries and search does not link to live web search.

The threshold controls the task. Dimensions are on the x-axis and lf strength is on the y-axis.

We would like to acknowledge the talented team Dupee, M. This is because a player may decide to bet big trade-off between precision and percent answered, on Daily Double or Final Jeopardy questions.
