What is IBM Watson?

Watson is an IBM supercomputer that combines artificial intelligence (AI) and sophisticated analytical software for optimal performance as a “question answering” machine. The supercomputer is named for IBM’s founder, Thomas J. Watson.

The Watson supercomputer processes at a rate of 80 teraflops (trillion floating-point operations per second). To replicate (or surpass) a high-functioning human’s ability to answer questions, Watson accesses 90 servers with a combined data store of over 200 million pages of information, which it processes against six million logic rules. The device and its data are self-contained in a space that could accommodate 10 refrigerators.

Watson's key components include:
       - SUSE Enterprise Linux Server 11, the fastest available Power7 processor operating system.

       -  15 terabytes of RAM.
  • 500 gigabytes of preprocessed information.
IBM'sDeepQA software, which is designed for information retrieval that incorporates natural language processing and machine learning.
