IBM's Watson: 'Jeopardy!' Win Just the Beginning
NEW YORK -- After soundly defeating its human competition in two "Jeopardy" quiz show matches, IBM's "Watson" computer is ready to move on to bigger and better things.
Watson beat two of the show's most successful and celebrated contestants - Ken Jennings and Brad Rutter - to win a $1 million grand prize that IBM donated to charity.
At an IBM event here Feb. 16 for press and analysts to view the airing of the final match, Katherine Frase, vice president of IBM Research, said, "It's not about the game." Frase noted that the Jeopardy game was just a way for IBM to showcase some of the advances it has made in computer science.
However, the Watson experiment indicates how truly important artificial intelligence and natural language processing can be for all kinds of business uses, including health care, law, call centers and a lot more, Frase said.
"After four years, our scientific team believes that Watson is ready for this challenge based on its ability to rapidly comprehend what the Jeopardy clue is asking, analyze the information it has access to, come up with precise answers, and develop an accurate confidence in its response," said David Ferrucci, the scientist leading the IBM Research team that created Watson. "Beyond our excitement for the match itself, our team is very motivated by the possibilities that Watson's breakthrough computing capabilities hold for building a smarter planet and helping people in their business tasks and personal lives."
"We think about it as decision support," Frase said of the application of the Watson technology to business uses. "We can say to the end user here is a recommended answer."
IBM's Watson signals a new era in computing, where computers will increasingly be built and optimized for specific tasks and be able to learn.
"Ultimately this was an empirical study," Ferrucci said of Watson and the Jeopardy game. "We used it to grow more context. It's a workload optimized system."
That system consists of: 10 racks (about 90) of IBM Power 750 servers with 2880 Power7 cores capable of running at 80 teraflops, 500 GB per second on-chip bandwidth, a 10 GB Ethernet network, 15 terabytes of memory and 20 TBs of clustered disk storage. Watson evaluated the equivalent of 200 million pages of content - or about 1 million books' worth - written in natural human language to find correct responses to the complex Jeopardy clues.
IBM created Watson as part of the company's effort to help business make sense of the explosion of data. Watson can analyze the meaning and context of human language and rapidly process information to find more precise answers to questions posed in natural language. IBM maintains that this holds enormous potential to transform how computers help people accomplish tasks in business, communities and their personal lives.
Meanwhile, Bernie Spang, director of strategy and marketing at IBM Software group, said with Watson's ability to understand natural language - unprecedented in history - its analytics technology is able to analyze massive amounts of data and arrive at the correct answer to a staggering variety of difficult questions across multiple industries.
As such, IBM and Nuance Communications on Feb. 17 announced a research agreement to explore, develop and commercialize Watson's advanced analytics capabilities in the health care industry.
"IBM is going to start moving beyond Jeopardy and we're announcing a partnership with Nuance where we're going to be making a commercial offering, based on Watson, available in the next 24 months," IBM's Ferrucci said.

The research and technology initiative will combine IBM's Deep Question Answering (QA), Natural Language Processing, and Machine Learning capabilities with Nuance's speech recognition and Clinical Language Understanding (CLU) solutions for the diagnosis and treatment of patients that provide hospitals, physicians and payers access to critical and timely information. The two companies expect the first commercial offerings from the collaboration to be available in 18 to 24 months.
Additionally, Columbia University Medical Center and the University of Maryland School of Medicine are contributing their medical expertise and research to the project, IBM said. For example, physicians at Columbia University are helping identify critical issues in the practice of medicine where the Watson technology may be able to contribute, and physicians at the University of Maryland are working to identify the best way that a technology like Watson could interact with medical practitioners to provide the maximum assistance.
"We are excited at the prospect of applying the Watson analytics technology to help create the next generation of electronic medical record systems and the next generation of computer diagnostic and decision support tools," Eliot Siegel, director of the Maryland Imaging Research Technologies Laboratory (MIRTL) University of Maryland School of Medicine, said in a statement. "We believe that this has the potential to usher in a new era of computer-assisted personalized medicine into health care to improve diagnostic accuracy, efficiency and patient safety."
In its press release on the partnership, IBM said Watson's ability to analyze the meaning and context of human language, and quickly process information to find precise answers can assist decision makers, such as physicians and nurses, unlock important knowledge and facts buried within huge volumes of information, and offer answers they may not have considered to help validate their own ideas or hypotheses.
"Combining our analytics expertise with the experience and technology of Nuance, we can transform the way that health care professionals accomplish everyday tasks by enabling them to work smarter and more efficiently," John E. Kelly III, senior vice president and director of IBM Research, said in a statement. "This initiative demonstrates how we plan to apply Watson's capabilities into new areas, such as health care with Nuance."
For example, a doctor considering a patient's diagnosis could use Watson's analytics technology, in conjunction with Nuance's voice and CLU solutions, to rapidly consider all the related texts, reference materials, prior cases and latest knowledge in journals and medical literature to gain evidence from many more potential sources than previously possible. This could help medical professionals confidently determine the most likely diagnosis and treatment options, IBM said.
"The combination of Nuance's speech recognition and existing Clinical Language Understanding solutions with the power of IBM's Watson technology will introduce unmatched clinical information and analytic technological advancements for healthcare," Paul Ricci, chairman and CEO of Nuance, said in a statement. "The initiative represents a logical step in Nuance's evolution, one that expands our capabilities from recognizing what was said to understanding the intent and providing guidance. The solutions we are developing with IBM will transform the capture, flow and use of clinical data, empowering health care organizations to drive smarter, more efficient clinical and business decisions."
Under the agreement, IBM and Nuance will jointly invest in a multi-year research initiative targeted to the applications of the Watson technology to assist in the diagnosis and treatment of patients in combination with Nuance's voice and clinical language solutions. In addition, IBM has licensed access to the Watson technology to Nuance. IBM and Nuance are currently engaged in a five-year joint-research initiative designed to advance next-generation natural language speech technologies, the results of which will be commercialized by Nuance. IBM also named Nuance its Preferred Business Partner for speech technologies and related professional services, aimed at complementing IBM's Industry Solutions portfolio.
Meanwhile, industry analysts view Watson as breakthrough technology that will go down in history.
Jonathan Yarmis, an independent industry analyst known as Doctor Disruptive for his focus on disruptive technologies, likens IBM's Jeopardy success with Watson to President John F. Kennedy's pledge of putting a man on the moon.
"When President Kennedy said we're going to put a man on the moon, what he did was took a series of disconnected efforts and gave them a focus and a deadline. That's what IBM did with Watson and the 'Jeopardy!' game. IBM did something that is remarkable and will have manifestations in both predictable and unpredictable ways. The science behind it is remarkable and this was an amazing engineering effort."
Moreover, Yarmis said, "The health care announcement with Nuance is just Step 1. Given Moore's law, in five to seven years this [Watson-like capabilities] is something your standard desktop computer will do. And two years after that it'll be on your tablet and on your cell phones the following year."
David Hill, an analyst with the Mesabi Group, said:
"On the surface, IBM's Jeopardy!-playing computer system Watson is impressive in its ability to answer complex, ambiguous questions expressed in natural language. In fact, Watson will likely be a centerpiece for IBM's centennial celebration in June. But Watson is more than just an impressive computing system. In fact, in the future after Watson's technology is used and deployed in multiple ways, we expect this week's 'Jeopardy!' matches will be seen as a historic event in information technology and big data and analytics that also portends much for society in general."
