“The Sixth International Conference on Web-Age Information Management，2005”，中文名称“第六届网络时代信息管理国际会议”将在10月11――13日在杭州花港饭店举行。会议由中国计算机学会数据库专业委员会发起，自2000年起在上海、西安、北京、成都、大连已连续成功地召开了5届。会议邀请了Peter Buneman等知名教授，将进一步促进我校与国内国际同行的交流，扩大我校在国内国际数据库研究领域的影响。
10月11日在杭州花港饭店花港厅由Jian Pei博士和Klaus-Dieter Schewe1教授主讲的两场Tutorial，欢迎广大同学和教师参加。
注：参加Tutorial的同学学校有专车接送，10月11日上午8:40在学校正门内侧有专车等。
Tutorial 1
时间地点：杭州花港饭店花港厅 10月11日上午9:00-12:00
主讲人(Presenter)： Jian Pei (Simon Fraser University, Canada)
内容简介(Abstract)：
In many emerging data intensive applications, including applications in sensor networks, stock market analysis, network communication management and intrusion detection, a tremendous volume of data arrives in the form of continuous streams. Online mining of data streams for knowledge discovery has become a novel and rapidly growing research direction in the last couple of years. Recently, a few exciting results have been published in this area, while at the same time, even more challenging problems have been identified. The tutorial will present a brief overview of the inherent challenges in mining data streams, a survey on the latest results in this line of research, and an introduction to some real-life applications.
主讲人背景(Background)
Jian Pei received the Ph.D. degree in Computing Science from Simon Fraser University, Canada, in 2002, under Dr. Jiawei Han's supervision. He also received the B. Eng. and the M. Eng. degrees, both in Computer Science, from Shanghai Jiao Tong University, China, in 1991 and 1993, respectively. He is currently an Assistant Professor of Computing Science at Simon Fraser University, Canada. In 2002 - 2004, he was an Assistant Professor of Computer Science and Engineering at the State University of New York (SUNY) at Buffalo, USA.
His research interests can be summarized as developing effective and efficient data analysis techniques for novel data intensive applications. Particularly, he is currently interested in various techniques of data mining, data warehousing, online analytical processing, and database systems, as well as their applications in bioinformatics. His current research is supported in part by the Natural Sciences and Engineering Research Council of Canada (NSERC) and the National Science Foundation (NSF) of the United States.
Since 2000, he has published over 60 research papers in refereed journals, conferences, and workshops, has served in the organization committee and the program committee of over 50 international conferences and workshops, and has been a reviewer for leading academic journals. He is a member of the ACM, the ACM SIGMOD, the ACM SIGKDD, and the IEEE Computer Society.
Tutorial2
时间地点：杭州花港饭店花港厅 10月11日上午14:40-17:40
主讲人(Presenter)：Klaus-Dieter Schewe1 (Massey University, New Zealand)
内容简介(Abstract)：
The tutorial addresses reasoning problems in Web Information Systems (WISs) that arise from the desire to personalise such systems to the various needs of their users, to adapt systems to different environments and access channels, to ensure that the service expected from the systems is delivered, and to guarantee consistency and integrity of the systems.For this the tutorial first presents of overview of the co-design approach to WIS design, which specifies systems on different levels of abstraction. The tutorial will focus on two of these levels emphasising views of WISs as dialogue systems and as data-intensive applications, respectively. The first of these views leads to modelling a story space describing how users navigate through the system, actors, i.e. clases of users, and tasks. The story space gives rise to an assignment-free process algebra, while actors define obligations and rights and rights of roles in a propositional deontic logic as well as preference rules on the story space that indicate different user profiles. On a lower level of abstraction the co-design approach emphasises content and functionality modelling, which requires support by views on some underlying database and operations on these views. Furthermore, the tutorial will discuss two more extensions dealing with hierarchies that enable different presentation granularity,and cohesion that permits adaptivity to technical restrictions such as channel bandwidth or end-devices.
The story algebras can in fact be represented by Kleene algebras with tests (KATs), which enable a simple form of system personalisation. Preferences and goals of users that are modelled by equations on the KAT can be exploited for simple, but effective term rewriting for the purpose of simplifying the story space according to a user's needs. The propositional deontic logic can be used to reason about tasks, for which proof obligations can be formulated. Using higher-order dynamic logic the operations on the views give rise to various proof obligations for consistency with respect to static and dynamic constraints,personalisation
and satisfiability of goals.
