Our paper "Lazy Updates: An Efficient Technique to Continuously Monitoring Reverse kNN" (with Muhammad Aamir Cheema, Xuemin Lin, Ying Zhang, and Wenjie Zhang) is accepted by VLDB 2009.
Mar 2009
Yi Chen, Xuemin Lin and I will give a three-hour tutorial
titled "Keyword Search on Structured and Semi-structured
Data" at the SIGMOD 2009 conference.

Our recent publications on Similarity Joins:
Top-k Set Similarity Joins (ICDE 2009), and Approximate
Entity Extraction with Edit Distance Constraints (SIGMOD
2009).

ARC-funded PhD Scholarship is available for the
"Effective and Efficient Video Search" project. Interested
candidates should contact me for further details.
My general research interests center around query processing and
optimization in database systems and novel data management
applications, including:
Similarity search (including kNN and top-k search) and
its applications (e.g., near duplicate object detection,
record linkage, and data archiving)
Integration of database and information retrieval
technologies (DB + IR) (e.g., effective and efficient keyword
search on the wikipedia data or freebase data)
Spatial, text, graph, and multimedia databases (e.g.,
indexing objects in high dimensional spaces)
Query processing issues in XML databases, Data Warehouses, and Data Mining
Below are a proper subset of projects that I
am working on. You can also find some general descriptions and
useful resources (paper, presentation/tutorial slides, prototype
systems, and datasets) there.

Selected Publications
So far, no system (Google Scholar, DBLP, MS Academic Search,
Arnetminer, CiteSeerX, or DBLife) can disambiguate publications of dozens of
"Wei Wang" well. This is dubbed the
Wei Wang challenge in DBLP.
Below is a list of my major publications and a fairly complete
list of publications can be found at My
