Building Watson: An Overview of the DeepQA Project

The IBM Watson system was designed to compete with humans on the Jeopardy! quiz show. This paper describes the DeepQA architecture that powers Watson, highlighting how it uses massive parallelism to analyze questions, gather evidence, and generate answers. The system integrates various AI techniques like natural language processing, information retrieval, knowledge representation, and machine learning to achieve human-level performance in question answering.
