Facutly from the Viterbi School of Engineering Information Sciences Institute are among scientists from eight universities who worked with IBM to advance the Question Answering (QA) technology behind the IBM Watson computing system.
Watson decisively beat the Jeopardy! quiz show’s two most successful and celebrated human contestants — Ken Jennings and Brad Rutter — in three segments that aired February 14–16, 2011.
“IBM Watson is the first step in how computers will be designed and built differently and will be able to learn and with the help of USC, we will continue to advance the QA technologies that are the backbone of this system,” said David Ferrucci, leader of the IBM Watson project team.
Watson's ability to understand the meaning and context of human language, and rapidly process information to find precise answers to complex questions, holds enormous potential to transform how computers help people accomplish tasks in business and their personal lives. Watson will enable people to rapidly find specific answers to complex questions. The ongoing research collaborations will help advance Watson's ability to improve all kinds of industries such as healthcre, banking, goverment, etc.
Viterbi School scientists are developing theories and computational techniques to help systems understand texts at a deeper level than is possible today. This work includes linguistic analysis of sentences, the collection of large amounts of background knowledge from the web, and the application of reasoning engines that draw conclusions from facts extracted from questions and possible answers.
“We believe the development of Watson is one of the most exciting illustrations of the power of modern computational technology to understand language, and foretells a lot more advances in the ability to answer complex questions, create summaries, and assist people looking for information,” said Eduard Hovy, director of the Information Science Institute’s Human Language Technology group. Other senior members of the ISI team are Jerry Hobbs and Hans Chalupsky.
"For the first time," Hovy continued, "there is a computing system that analyzes natural language and other language complexities in which humans excel at understanding and computers do not. In this case, IBM has designed a learning system that can analyze information and respond to questions. It's the next stage in computing." Hovy was quoted in reports on Watson that appeared in the L.A. Times, Wall Street Journal, and other media.
Massachusetts Institute of Technology (MIT), University of Texas, Rensselaer Polytechnic Institute (RPI), University at Albany (UAlbany), University of Trento, University of Massachusetts and Carnegie Mellon University also are working with IBM on the development of a first-of-its-kind open architecture that enables researchers to efficiently collaborate on underlying QA capabilities and then apply them to IBM’s Watson system.
The University of Southern California's Viterbi School of Engineering is a leading research institution, with scholars, students, and visitors from around the world. Its Information Sciences Institute has one the world's strongest programs in artificial intelligence.
