Xin (Luna) Dong
I am currently a researcher in the Data Management Department at
AT&T Labs - Research. I received my Ph.D. in
Computer Science and Engineering at
Univ. of Washington. Before coming to the United States, I
obtained a M.S. in Computer Science at
Peking University, and a B.S. in Computer Science at
Nankai University in China.
You can find my C.V.
here.
Research Interest
The goal of my research is to help people organize, access, and
search information effectively and efficiently. My research aims at
answering the following questions:
- The amount of information produced in the world increases by
30% every year and this rate will only go up. On the one hand,
how can we take the full advantage of the abundant information
to improve quality of data? On the other hand, how can we help
users find the answers that address their questions without
overwhelming them by the huge amount of relevant information?
- Nowadays more and more data-management applications need to
integrate a large volume of heterogeneous data, but data
integration often requires significant upfront efforts and
technical expertise. How can we enable data sharing with a
minimum cost and how can we still guarantee quality of the
shared data?
- Data exist in various forms: structured, semi-structure, and
unstructured. How to realize the full potential of structure
explicitly or implicitly existing in data to best fulfill
people's information needs?
- The world contains rich associations: between real-world
entities, between data sources, and between data items. How to
discover and leverage such associations to facilitate search?
- How to help non-technical-savvies to best organize, access,
and understand information?
In particular, my current research interests include
- Data integration
- Data cleaning
- Web search
- Record linkage
- Personal information management, community information
management, enterprise data management.
Projects
Currently my research focuses on two directions:
source-dependence discovery for data cleaning and data integration,
and data integration with uncertainty.
 Solomon---Detecting
dependence between data sources
The Internet accelerates the rate of information being
produced and eases duplication and transmission of data across
data sources. Solomon aims at discovering dependencies between
data sources and leveraging such knowledge for deciding truth
from conflicting information and for efficiently answering
queries over a set of data sources. [Vision
paper][Talk]
 UDI---Data
Integration with Uncertainty
As the scope of data integration applications broadens, data
integration systems need to handle uncertainty at various levels
and do so in a principled fashion. Our goal in the project is to
build a system that can quickly provide search services over a
set of heterogeneous data sources without requiring strenuous
work on setting up the precise mappings between the sources. [Talk][DBClip]
My recent projects include
-
Semex---Personal information management system
-
Woogle---Web-service search engine
-
Piazza---Peer data management system
