Abstract

Can we create a system that can learn to understand political speeches well enough to determine the speakers' viewpoints? Can we improve information retrieval by using link analysis, as is famously done in Web search, if we are dealing with documents that don't contain hyperlinks? And how can these two questions form the basis of a coherent talk? Answer: graphs! Joint work with Oren Kurland, Bo Pang, and Matt Thomas.
