Experience
PHP/MySQL Web Service
(Sep 2006 current)
We developed a web service with PHP/MySQL to provide online RSVP and other functions.
Construction and Visualization of Chinese Phrases
(Master project in Dept. of Computer Science, University of Pittsburgh, May Aug 2006)
We developed a grammar in visual language for the construction of Chinese phrases in this project.
Chinese characters, phrases and sentences can be generated by the syntactic rules in the grammar. Their
meanings can be captured by the semantic rules defined in this grammar.
Core Vocabulary for Chinese Mandarin
(Project with Semantic Compaction Systems, May Aug 2006)
We designed criteria to evaluate different corpora for linguistic and speech research work on
Chinese Mandarin and selected the most suitable corpus for Minspeak system. Based on this corpus, we
developed a Minspeak-Application-Program word list.
Speech Act Classification in Emails
(Summer Intern, Institute of Creative Technology (ICT), USC, May Jul 2005)
We used several machine learning methods to classify different emails into several speech act
categories, which are used for detecting people s roles in communication. We also designed and
implemented a user interface with PHP/MySQL that allows new annotations added into the database in
the future.

Phrase-based Joint Probability Model for Machine Translation
(Course project in Dept. of Computer Science, University of Pittsburgh, Jan Apr 2005)
We implemented a phrase-based joint probability model and applied it to Chinese-English
translation in this project.
Email Summarization
(Intern, Microsoft Research Asia, Beijing, China, Jan Apr 2004)
We focused on extracting email summaries from information in email thread reply chains. Our
approach considered both the titles and contents of individual emails and the key words in a set of
emails within one reply chain.
Semantic Cohesion Computation between Chinese Words
(Master project in CS Dept., Tsinghua University, China, Sep 2001 Jan 2004)
We implemented three sub-projects in this work: classifying each word in collocations into its
semantic class; selecting appropriate representations for semantic classes based on HowNet system; and
building a semantic template bank.
Part-time Translator (Feb May 2003)
English-Chinese translation for part of the textbook Artificial Intelligence: A Modern Approach
(by Stuart Russell and Peter Norvig)
Identifying Chinese Chunk based on Maximum Entropy Model
(Research Assistant, Artificial Intelligence Lab, CS Dept., Tsinghua University, Jan Jul 2001)
We built a Chinese chunk analysis system based on maximum entropy model. This system divides
a sentence (with POS tag labels on each word) into several chunks and decides the type of each chunk.
Mini C++ Compiler
(Course Project in CS Dept, Tsinghua University, China, Sep.2000 Jan.2001)
We implemented a mini compiler for a simplified version of C++. The simplified language includes
most basic features of object-oriented language but has limited operations and expressions.
Teaching Experience
Aug. 2004 Aug. 2006, Teaching Assistant, Dept. of Computer Science, University of Pittsburgh
I was the TA for the following courses: Advanced Operating Systems (CS2510), Advanced System
Software (CS1651), Artificial Intelligence (CS1571) and Intermediate Programming Using Java
(CS0401).
Sep. 2002 Jan. 2003, Teaching Assistant, Dept. of Computer Science, Tsinghua University
I was the TA for an undergraduate course: Introduction to Artificial Intelligence.
