With an increasing use of data mining tools and techniques, we envision that a Knowledge Discovery and Data Mining System (KDDMS) will have to support and optimize for the followi...
— High-speed Internet access in subway and railway systems has been receiving more and more attention in recent years. A critical issue for such application is the ground to trai...
We develop a query algebra that supports efficient assertion retrieval--a natural extension of instance retrieval. The algebra is based on previously developed techniques for index...

Bitmap indices are efficient data structures for processing complex, multi-dimensional queries in data warehouse applications and scientific data analysis. For high-cardinality at...
In this paper, we study the problem of processing multiple queries in a wireless sensor network. We focus on multiquery optimization at the base station level to minimize the numb...
