On behalf of the Organizing Committee, we would like to welcome you to the proceedings of the 10th International Conference on Database Systems for - vanced Applications (DASFAA 2005). This conference provides an international forumfortechnicaldiscussionamongresearchers, developersandusersofdatabase systems from academia, business and industry. DASFAA focuses on research in databasetheory, andthedevelopmentandapplicationsofadvancedDBMSte- nologies. This was the second time that this conference has been held in China, the ?rst time was in Hong Kong in 2001. China is the third largest nation in terms of size, with the largest population in the world. The capital, Beijing, is a great metropolis, famous in Asia and throughout the world. We therefore were most privileged to host this conference in this renowned location. This volume contains papers selected for presentation and includes the three keynote talks, by Dr. Philip Yu, Prof. Elisa Bertino and Prof. Deyi Li. The conference also featured two tutorials: (1) Data Mining Techniques for MicroarrayDatasets, byLeiLiu, JiongYangandAnthonyTung, and(2)Pattern Management: Models, Languages, andArchitecturalIssues, byBarbaraCatania. ThetechnicalprogramoftheconferencewasselectedbyadistinguishedProgram Committee led by two PC Co-chairs, Lizhu Zhou and Beng Chin Ooi. The 89 members, half of whom reside outside Asia, made the committee a truly inter- tional one. They faced a di?cult task in selecting 67 regular papers and 15 short papersfrommanyverygoodcontributions.Thisyearthenumberofsubmissions, 302, was a record high for DASFAA conferences since the ?rst conference held in 1989 in Seoul, Korea. We wish to express our thanks to the Program Committee members, external reviewers, and all authors for submitting their papers to this co

This volume contains the papers selected for presentation at the Third Paci?c- Asia Conference on Knowledge Discovery and Data Mining (PAKDD-99)held in the Xiangshan Hotel, Beijing, China, April 26-28, 1999. The conference was sp- sored by Tsinghua University, National Science Foundation of China, Chinese Computer Federation, Toshiba Corporation, and NEC Software Chugoku, Ltd. PAKDD-99 provided an international forum for the sharing of original research results and practical development experiences among researchers and application developers from di?erent KDD-related areas such as machine lea- ing, databases, statistics, knowledge acquisition, data visualization, knowled- based systems, soft computing, and high performance computing. It followed the success of PAKDD-97 held in Singapore in 1997 and PAKDD-98 held in A- tralia in 1998 by bringing together participants from universities, industry, and government. PAKDD-99 encouraged both new theory/methodologies and real world - plications, and covered broad and diverse topics in data mining and knowledge discovery. The technical sessions included: Association Rules Mining; Feature Selection and Generation; Mining in Semi, Un-structured Data; Interestingness, Surprisingness, and Exceptions; Rough Sets, Fuzzy Logic, and Neural Networks; Induction, Classi?cation, and Clustering; Causal Model and Graph-Based Me- ods; Visualization; Agent-Based, and Distributed Data Mining; Advanced Topics and New Methodologies. Of the 158 submissions, we accepted 29 regular papers and 37 short papers for presentation at the conference and for publication in this volume. In addition, over 20 papers were accepted for poster presentation.
