Some Interesting Papers of ACM SIGMOD Conference 2009Posted: August 8, 2009 Filed under: Research | Tags: database, paper, SIGMOD 3 Comments
ACM SIGMOD Conference 2009 was held in Providence, Rhode Island from June 29 through July 2. Then, the electronic proceedings are available online. Among many nice papers, I tried to choose some interesting papers as follows:
MapReduce & Hadoop
- “A Comparison of Approaches to Large Scale Data Analysis,” Andrew Pavlo, Samuel Madden, David DeWitt, Michael Stonebraker, Alexander Rasin, Erik Paulson, Lakshmikant Shrinivas and Daniel Abadi.
Some of the authors are members of vertica, a parallel database. Prof. Dwitt strongly attacked MapReduce (MapReduce: A major step backwards, MapReduce II). So, I wonder how did they benchmark both architectures.
- “Minimizing the Communication Cost for Continuous Skyline Maintenance,” Zhenjie Zhang, Reynold Cheng, Dimitris Papadias, Anthony K. H. Tung.
- “Scalable Skyline Computation Using Object-based Space Partitioning,” ZHANG Shiming, Nikos Mamoulis, David Cheung.
- “Kernel-Based Skyline Cardinality Estimation,” Zhenjie Zhang, Yin Yang, Ruichu Cai, Dimitris Papadias, Anthony and K. H. Tung.
Since I first met the skyline problem, I have been always interested in skyline queries. Considering multi-criteria, Skyline queries retrieve the best tuples among multi-dimensional objects.
Graph Query Processing
- “3-HOP: A High-Compression Indexing Scheme for Reachability Query,” Ruoming Jin, Yang Xiang, Ning Ruan, and Dave Fuhry.
Rechability query is to compute whether two given vertices are rechable, or not. Rechability query is one of the most fundamental operations in graph querying. it can be usually used in a primitive operation for complex graph queries.
RDF Query Processing
- “Scalable Join Processing on Very Large RDF Graphs,” Thomas Neumann and Gerhard Weikum.
The issue with which I’m primarily concerned is RDF query processing. As linked data are gaining attention, this issue will be more dealt with in the database community.
Spatial Query Processing
- “Quality and Efficiency in High Dimensional Nearest Neighbor Search,” Yufei Tao, Ke Yi, Cheng Sheng and Panos Kalnis.
- “Continuous Obstructed Nearest Neighbor Queries in Spatial Databases,” Yunjun Gao and Baihua Zheng.
- “A Revised R*-tree in Comparison with Related Index Structures,” Norbert Beckmann and Bernhard Seeger.
While I was taking M.S. program, I studied many spatial query processing issues. Hence, I try to keep in touch with recent spatial database issues.
They are seem to be very interesting. Later, I will post paper reviews about above papers.
