Talk Title: Unifying Logic and Probability: A Progress Repo

rt

Talk Abstract:
Intelligent agents must be able to handle the comp

lexity and uncertainty of the real world. First-order logic is a good repre

sentation for complexity, and probabilistic graphical models for uncertain

ty. Unifying the two is a long-standing goal of AI. This talk samples the s

tate of the art in this area, in four parts: representation, inference,

learning, and applications. First, I will introduce Markov logic, a lang

uage that combines logic and probability by attaching weights to first-orde

r formulas and viewing them as templates for features of Markov random fiel

ds. Second, I will describe probabilistic theorem proving, an inference p

rocedure that combines theorem proving and graphical model inference. Third

, we look at statistical relational learning, with a focus on learning th

e structure and weights of Markov logic networks. Fourth, we apply these t

echniques to problems in natural language processing, including coreferenc

e resolution and semantic parsing. (Joint work with Jesse Davis, Vibhav Go

gate, Stanley Kok, Daniel Lowd, Aniruddh Nath, Hoifung Poon, Math Rich

ardson, Parag Singla, Marc Sumner, and Jue Wang.)
