v
Team
leader of UMD’s participation in the High Accuracy Retrieval of Documents
(HARD) track of Text REtrieval Conference (TREC) 2003. TREC is organized by the
National Institute of Standards and Technology (NIST), and is the most
prestigious gathering of the best scientists and teams in the world that are
working on problems/techniques in information retrieval (IR).
Ø
Responsible
for the design of the overall approach taken by the UMD HARD team.
Ø
Designed
and implemented several key components of the system, including the automatic
query expansion module, the document re-ranking module, and the ranked-list
merging module.
Ø
Led
effort in analyzing results, and writing report about the effort of the UMD
HARD team.
Ø
Participated
in the TREC conference to present the work of the team.
v
Team
leader of the Cross Language Information Retrieval (CLIR) team in UMD’s
participation in the surprise language experiment and dry-run of Translingual
Information Detection, Extraction, and Summarization (TIDES) project, which is
a research project funded by the Defense Advanced Research Projects Agency
(DARPA).
Ø
Responsible
for the overall design of a rapidly retargetable CLIR interactive system
(called MIRACLE) for processing previous unseen languages.
Ø
Led
the team to complete the implementation of the MIRACLE system for Hindi
language within a month. MIRACLE was the first interactive CLIR system for
Hindi in the world.
Ø
Led
the team to complete the design and implementation of the batch CLIR systems
for Hindi language within a month and for Cebuano language within 10 days.
Initial test results showed that our batch CLIR systems achieved comparable
results to monolingual Hindi retrieval.
Ø
Wrote
a journal paper presenting the UMD CLIR team’s effort in surprise language
experiment. Listed as the first author of the paper.
v
Team
leader of the CLIR team in UMD’s participation in the interactive track of the
Cross Language Evaluation Forum (iCLEF) in the past two years. iCLEF is a TREC
equivalent conference in Europe, and is a specialized gathering for CLIR
researchers.
Ø
Responsible
for the overall design of the experiments run by the UMD team, and conducted
major parts of the experiments.
Ø
Responsible
for the design and extension of the user-assisted query translation approach
for interactive Cross Language Information Retrieval (CLIR), which was the main
theme of UMD’s participation in iCLEF in the past two years.
Ø
Led
the effort in analyzing results, and wrote reports and presentations about
UMD’s iCLEF effort in the past two years. Listed as the first author of the
reports.
v
Team
leader of the UMD team’s participation in the Topic Detection and Tracking (TDT) track of TREC 2002.
Ø
Responsible
for the overall design and implementation of a topic tracking system using
language modeling and information retrieval techniques. The system achieved
comparable tracking results to the state of art in TDT 2002 experiment.
Ø
Led
effort in analyzing results, wrote reports, and presented at the TDT workshop
of TREC conference. Listed as the first author of the report.
Research
Fellow (7/99 -
2/02)
School of
Computing, The Robert Gordon University, Aberdeen, UK.
v
Responsible
for the design of a Web user context learning model that uses both the user’s
personal search history and collaborative information from people who share the
same interests to improve search effectiveness. Responsible for the
implementation of the key context learning components in a Web search
engine. Published several conference
papers on this topic.
v
Researched,
surveyed, and compared theories and models about context, context information
of users, and context models in communication, linguistic process, and
information retrieval. Wrote a white paper about the outcome of the research,
and based on the report, extended a context learning model in traditional
information retrieval to a context learning model in Web information retrieval.
v
Responsible
for the design of a role-based context model for modeling the user in
information retrieval. The role model extends traditional context model by
viewing the user’s actions from task-oriented view.
v
Conducted
text mining in several Web search log collections. Identified the problem of
lacking sensible session boundaries in Web logs, which is a problem for context
learning for Web information retrieval.
v
Designed
and implemented time interval based session identification method. Conducted
experiments to test the method on several Web log collections. The results show
that the method can provide reasonable boundaries for our context learning
purpose. Wrote several conference papers about this work.
v
Designed
and implemented an evidence combination method, based on Dempster-Shafer
theory, for Web search session identification. The method uses the outcome of
time interval method and that of the search pattern method for Web search
session identification as input, and generates statistical based inference
about the possibility of having session delimiters at a given point. Conducted
an experiment and demonstrated the effectiveness of the method. A journal
paper, which I am the first author, was published on one of the most
prestigious journals of IR research.

Research Assistant
(12/95 - 7/01)

v
Designed
a computational model for interpreting English referring expressions in
intelligent multimodal interfaces. The model is designed to handle reference
ambiguities that could involve attributes of objects in the application domain
and/or attributes of graphic icons on the screen. This kind of reference ambiguities,
which I called “source ambiguities”, had been mentioned before in the
literature, but it was my model that provides a computational means for
resolving them for the first time.
v
Designed
a logical meaning representation language (MRL) to represent the meaning of
natural language sentences. The advantages of the MRL is that it was designed
to handle source ambiguity, and it provides a uniform meaning representation
from the phase before the ambiguities are resolved all the way to the phase
that the ambiguities have been solved. This again was the first MRL for
handling source ambiguities.
v
Developed
an intelligent multimodal dialogue system to demonstrate the ability of the
computational model for handling source ambiguities. I conducted experiment
that involves human subjects to interact with the system. The results show that
there was statistically significant difference concerning the user’s experience
with the system with the ability of resolving source ambiguity and that
without. The former is much preferred by the user.
v
Researched,
surveyed, and compared different theories and models in intelligent multimodal
systems. Identified source ambiguities as an important and interesting problem
that had not been fully studied in the literature. This work motivated me to
work on resolving source ambiguities.

v
Designed
a resolving method for three-value logical equations, and constructed a
computational model for detecting hazards in combinational circuits. The design
was published in a journal paper, where I am the first author.
v
Built
a software system that identifies potential hazards existing in a combinational
circuit based on the logical description of the circuit. The software was given
the second place award in FengRu Cup student research competition in 1995.
v
Researched,
surveyed, and compared existing theories and methods in resolving three-value logical
equations, and its application to detecting hazards.
v

dissertation that discusses the above designs and implementations received an
excellent grade.
