Title:       Model Structure, Data, and Learning Bias in Weakly-Supervised
Natural
              Language Processing

Abstract:

I will discuss some of my recent research in weakly-supervised natural
language processing, focusing on inducing shallow syntax (parts of speech)
and lexical semantics (word sense). Common themes include: (1) designing
models to capture intuitions about the linguistic phenomena of interest,
(2) leveraging large corpora of unannotated data, and (3) biasing learning
for the given dataset and task. Tools used to achieve these goals include
word embeddings, Brown clusters, "deficient" probabilistic modeling, and
models of sentence corruption based on n-gram language models. The result
is state-of-the-art performance on standard part-of-speech and word sense
induction tasks.

This is joint work with Mohit Bansal, Jing Wang, and several collaborators
from Carnegie Mellon.

Research at TTIC Seminar Series

TTIC is hosting a weekly seminar series presenting the research currently
underway at the Institute. Every week a different TTIC faculty member will
present their research.  The lectures are intended both for students
seeking research topics and adviser, and for the general TTIC and
University of Chicago communities interested in hearing what their
colleagues are up to.

To receive announcements about the seminar series, please subscribe to the
mailing list: https://groups.google.com/a/ttic.edu/group/talks/subscribe
