Dear faculty and students,

We look forward to seeing you this Tuesday, February 23rd, at noon in NSH
3305 for AI lunch. To learn more about the seminar and lunch, or to
volunteer to give a talk, please visit the AI Lunch webpage
<http://www.cs.cmu.edu/~aiseminar/>.

On Tuesday, Professor Scott Fahlman <http://www.cs.cmu.edu/~sef/> will give
a talk titled "Knowledge-Based AI Using Scone."

*Abstract*: In the early days of the AI field, the focus was mostly on
symbolic knowledge, reasoning, and search, plus a little bit of machine
learning to gather the necessary knowledge. More recently, the focus has
shifted almost completely to ML, Big Data, and Deep Learning, and there has
been some exciting progress in these areas. I will argue that for
human-like, human-level AI, we are going to need both approaches: the ML
stuff to handle the sensory-motor tasks, and the symbolic stuff for
semantics, complex reasoning, and "conscious" thought.

In the remainder of the talk, I will give a high-level overview of the
open-source Scone knowledge-base system, which my research group has been
working on for most of the last decade. I will describe how Scone handles
inheritance of information through the "is a" hierarchy, default reasoning
with exceptions, and statements about statements, and how we scale the
system up to millions of entities and statements -- on a laptop.

Perhaps the most unusual feature of Scone is its multiple-context
mechanism, which allows us to represent many slightly different
world-models within the same knowledge base. Scone's contexts are used for
modeling and reasoning about information that changes from one time-point
to another; hypotheses and counter-factuals; the different knowledge-states
and belief-states of various characters; lies and deception; and in many
other ways. Contexts are our secret weapon and our Swiss Army Knife.

Finally, I will give a quick overview of the Scone project's current status
and what we are working on, now and in the future.

Best,

Ellen and Ariel
