Recent News
- (7/3/2008) Launching Search@ICS: I am glad to our research
prototype has been launched on the ICS Homepage
that can support interactive, fuzzy search for ICS people and general pages at ICS.UCI.EDU.
- (4/1/2008) Launching PSearch: I am glad to release
the PSearch Prototype to support interactive, fuzzy search for UCI Directory.
- (3/31/2008) This quarter I am teaching CS122B
and CS224.
- (2/22/2008) New SIGMOD08 paper: The conference has accepted
our paper titled "Cost-Based Variable-Length-Gram Selection for String Collections to
Support Approximate Queries Efficiently", a joint work with Bin Wang and Xiaochun
Yang when they visited our place last fall. The paper solves several open,
important problems not addressed in our VLDB07 VGRAM paper.
- (2/1/2008) New Visitor: I am glad that Guoliang Li from
Tsinghua University is visiting my research team for about four months.
- (12/12/2007) Today I attended a local computer industry forum
about the computer cluster workforce in Orange County. There is
an excellent survey
on the needs of computer cluster workforce in the county. One interesting
finding is that the county is facing the challenge of not being able
to find enough workers in the IT industry. The survey also gives
us some thoughts on how we design our education curriculum to meet the
need of the industry.
- (12/2007) I am looking for a motivated BS/MS student for an
independent research project. Requirements: strong java
programming skills. Please contact me if you are interested.
- (10/2007) New paper on approximate string matching: Our
recent paper titled "Efficient Merging and Filtering Algorithms for
Approximate String Searches" by Chen Li, Jiaheng Lu, and Yiming Lu
will appear in ICDE 2008. We developed new algorithms and indexing
structures that can significantly improve the performance of
approximate string search.
- (10/2007) New NSF Grant: We received an NSF grant of $95K
for our proposal titled "SGER: Answering Approximate String Queries
Using Variable-Length Grams."
- (8/2007) Visitors: Bin Wang and Xiaochun Yang are visiting our
team again this summer. We will continue working on topics related to
approximate query answering.
