Great public debates have sparked our imagination since the days of ancient Greece. This intellectual tradition will take on new life at the IBM think conference in San Francisco, when IBM Research (US) and Intelligence Squared U.S. host a live public debate on Monday, February 11 between a human and an AI.
At the center is IBM Project Debater (US), the first AI system that can debate humans on complex topics. To do this effectively, the system must gather relevant facts and opinions, form them into structured arguments, and then use precise language in a clear and persuasive way.
Project Debater’s first live public debate took place in June before a small audience. At think, Project Debater will face off against a champion debater in front of a large in-person audience, with many more watching via livestream (watch here (US) on Feb. 11 at 5 pm PT).
Harish Natarajan, Project Debater’s opponent at think 2019, is 2016 World Debating Championships Grand Finalist and 2012 European Debate Champion. Harish holds the world record for most debate competition victories.
Project Debater’s opponent is 2016 World Debating Championships Grand Finalist and 2012 European Debate Champion Harish Natarajan. Harish holds the world record for most debate competition victories. Each side has only 15 minutes to prep for the debate, during which they prepare arguments for and against a given thesis statement. Both sides will then present a four-minute opening statement, a four-minute rebuttal, and a two-minute summary. The exhibition promises to be lively, with attendees including top debaters from Bay Area schools and more than 100 journalists.
Harish is the highest caliber opponent Project Debater has faced, so we expect the technology will be pushed to its limits. Still, it may be that some in the audience don’t fully grasp the difficulty of preparing AI for such a challenge. Here’s more on what goes into a debate:
These capabilities have been developed over the course of the project and our team has published more than 30 research papers (US) to document and share what we’ve learned.
Though the format and challenge of debate have allowed us to shape Project Debater’s capabilities, we envision a future for the technology beyond the podium. It could be used, for instance, to promote more civil debates in online comment forums or by an attorney preparing for a trial where it could review legal precedents and test the strengths and weaknesses of a case using a mock legal debate. In the financial services industry, Debater could identify financial facts that either support or undermine an investment strategy. Or it could be applied as a voice interaction layer for various complex customer experiences, or even to improve critical thinking and critical writing skills of youngsters.
Debate is all about language. Mastering human language is one of the most ambitious goals of AI. Project Debater moves us one step closer in this journey. In the grand scheme, Project Debater reflects the mission of IBM Research to develop broad AI that learns across different disciplines to augment human intelligence. It absorbs large sets of information and perspectives in the quest for one simple goal: to help us make better and more informed decisions.
If you’re interested in experiencing the AI technology yourself, check out Project Debater – Speech by Crowd, which uses the core AI behind Project Debater to collect arguments from large audiences and automatically construct persuasive viewpoints to support or contest a topic such as, “we should ban the sale of violent video games to minors.” After Monday’s debate, we’ll post a new topic and hope you’ll make your voice heard.
