Abstract

Data quality can be defined as the fitness for the intended use. Data quality control becomes one of major challenges for the modern information society. In this talk, we will introduce the concept of data quality from organizational, architectural and computational angles. After a brief overview of key components of computational data quality research including data linking, data constraints and data uncertainty, we will discuss the recent work from the database research community on data provenance and lineage.

Professor Xiaofang Zhou is a Professor of Computer Science at the University of Queensland. He is the Head of the Data and Knowledge Engineering Research Division at UQ, and the Convenor of Australian Research Council (ARC) Research Network in Enterprise Information Infrastructure. He received his BSc and MSc degrees in Computer Science from Nanjing University, China, and PhD in Computer Science from the University of Queensland. Before joining UQ in 1999, he worked as a researcher in CSIRO, leading its Spatial Information Systems group. His research focus is to find effective and efficient solutions for managing, integrating and analyzing very large amount of complex data for business and scientific applications. He has been working in the area of spatial and multimedia databases, data quality, high performance query processing, Web information systems and bioinformatics, co-authored over 150 research papers with many published in top journals and conferences such as SIGMOD, VLDB, ICDE, ACM Multimedia, The VLDB Journal, ACM Transactions and IEEE Transactions. He was the Program Committee Chair of IFIP Conference on Visual Databases (VDB 2002), Australasian Database Conferences (ADC 2002 and 2003), International Conference on Web Information Systems Engineering (WISE 2004), Asia Pacific Web Conferences (APWeb 2003 and 2006), International Conference on Databases Systems for Advanced Applications (DASFAA 2009), and a Vice Program Committee Chair for International Conference on Data Engineering (ICDE 2009). He has been on the program committees of over 100 international conferences, including SIGMOD, VLDB, ICDE and WWW. He is on the editorial board of World Wide Web Journal, Information Processing Letters, Encyclopedia of Database Systems and Web Information System Engineering book series by Springer.
