[ChimeText] 16 Jul (tomorrow!): Xiong Deyi / Linguistically Annotated BTG for Statistical Machine Translation

[Min-Yen Kan]

Hi all:

A reminder of our next CHIME Text Processing Seminar tomorrow
afternoon.  Don't forget about Prof. Doug Oard's talk on Thursday as
well.  Finally, stay tuned for our post SIGIR Yahoo! Research Lab
talks on 25 July Friday morning.

See you there!

Title: Linguistically Annotated BTG for Statistical Machine Translation
Date: Wednesday, 16 Jul, 3-4pm
Venue: Seminar Room 3 (COM1 02-12)

ABSTRACT:

Bracketing Transduction Grammar (BTG) is a natural choice for
effective integration of desired linguistic knowledge into statistical
machine translation (SMT). In this talk, we introduce a Linguistically
Annotated BTG (LABTG) for SMT. It conveys linguistic knowledge of
source-side syntax structures to BTG hierarchical structures through
linguistic annotation. From the linguistically annotated data, we
learn annotated BTG rules and train linguistically motivated phrase
translation model and reordering model. We also present an annotation
algorithm that captures syntactic information for BTG nodes. The
experiments show that the LABTG approach significantly outperforms a
baseline BTG-based system and a state-of-the-art phrase-based system
on the NIST MT-05 Chinese-to-English translation task. Moreover, we
empirically demonstrate that the proposed method achieves better
translation selection and phrase reordering.

BIODATA:

Xiong Deyi received his Ph.D. from the Institute of Computing
Technology of Chinese Academy of Sciences. His research interests
include statistical machine translation, Chinese language processing,
information extraction, and statistical parsing. He is currently a
research fellow at the Institute for Infocomm Research of Agency for
Science, Technology and Research (I2R,A-STAR).
