I will briefly discuss the main features of GeoDec and show some demonstrations of the system. Then, I will focus on one specific decision making query type within GeoDec that we introduced recently, termed “Spatial Skyline Queries (SSQ)”. Given a set of data points P and a set of query points Q, an SSQ retrieves those points of P which are not dominated by any other point in P considering their distances to query points in Q. I present one of our algorithms, VS2, to address SSQ and show some experimental results. The main intuition and novelty behind our approach is that we exploit the geometric properties of the SSQ problem space to avoid the exhaustive examination of all the point pairs in P and Q. Bio. Cyrus Shahabi is currently an Associate Professor and the Director of the Information Laboratory (InfoLAB) at the Computer Science Department and also a Research Area Director at the NSF's Integrated Media Systems Center (IMSC) at the University of Southern California. He received his B.S. in Computer Engineering from Sharif University of Technology in 1989 and then his M.S. and Ph.D. degrees in Computer Science from the University of Southern California in May 1993 and August 1996, respectively. He has two books and more than hundred articles, book chapters, and conference papers in the areas of databases, GIS and multimedia. Dr. Shahabi's current research interests include Geospatial and Multidimensional Data Analysis, Peer-to-Peer Systems and Streaming Architectures. He is currently an associate editor of the IEEE Transactions on Parallel and Distributed Systems (TPDS) and on the editorial board of ACM Computers in Entertainment magazine. He is also a member of the steering committees of IEEE NetDB and the general co-chair of ACM GIS 2007. He serves on many conference program committees such as VLDB 2008, ACM SIGKDD 2006 to 2008, IEEE ICDE 2006 and 2008, SSTD 2005 and ACM SIGMOD 2004. Dr. Shahabi is the recipient of the 2002 National Science Foundation CAREER Award and 2003 Presidential Early Career Awards for Scientists and Engineers (PECASE). In 2001, he also received an award from the Okawa Foundations. -- ----------------------------------------------------------------------- 中野 美由紀 東京大学 生産技術研究所 喜連川研究室 Miyuki NAKANO Institute of Industrial Science, Univ. of Tokyo miyuki [at] tkl.iis.u-tokyo.ac.jp
