Research Interests/Experience
Exploring
hybrid approaches to natural language processing (NLP) that make use of both
statistical and knowledge-based techniques is my primary interest, although
this is a general topic that can have many different applications.
I am also
interested in semi-supervised machine learning methods, especially in relation
to understanding natural language. We
started to investigate the tip of this iceberg in Tom Mitchell’s first Read the Web course
and are currently still exploring it.
Previously, I worked with Teruko Mitamura and Eric Nyberg on using such an approach to classify questions in terms of their expected
answer type for the JAVELIN II
project. Before that, we worked on extending
the KANTOO machine translation system
to make use of lexical information in VerbNet and
before that, to facilitate knowledge acquisition in the HALO project.
As an
undergraduate, I worked with Irene Langkilde-Geary
(who started the BYU NLP lab) on the topic addressed by the
corresponding paper below.
