Book Description
With the ever increasing volume of data, data quality problems abound. Multiple, yet different representations of the same real-world objects in data, duplicates, are one of the most intriguing data quality problems. The effects of such duplicates are detrimental; for instance, bank customers can obtain duplicate identities, inventory levels are monitored incorrectly, catalogs are mailed multiple times to the same household, etc. Automatically detecting duplicates is difficult: First, duplicate representations are usually not identical but slightly differ in their values. Second, in principle all pairs of records should be compared, which is infeasible for large volumes of data. This lecture examines closely the two main components to overcome these difficulties: (i) Similarity measures are used to automatically identify duplicates when comparing two records. Well-chosen similarity measures improve the effectiveness of duplicate detection. (ii) Algorithms are developed to perform on very large volumes of data in search for duplicates. Well-designed algorithms improve the efficiency of duplicate detection. Finally, we discuss methods to evaluate the success of duplicate detection. Table of Contents: Data Cleansing: Introduction and Motivation / Problem Definition / Similarity Functions / Duplicate Detection Algorithms / Evaluating Detection Success / Conclusion and Outlook / Bibliography

Book Description
From the Pulitzer Prize-winning author of A Thousand Acres comes a brilliant literary thriller set in Manhattan that’s “as taut and chilling as anything Hitchcock put on film" (San Francisco Chronicle). “A first-rate cliffhanger.” —The New York Times Book Review Alice Ellis is a Midwestern refugee living in Manhattan. Still recovering from a painful divorce, she depends on the companionship and camaraderie of tightly knit circle of friends. At the center of this circle is a rock band struggling to navigate New York’s erratic music scene, and an apartment/practice space with approximately fifty key-holders. One sunny day, Alice enters the apartment and finds two of the band members shot dead. As the double-murder sends waves of shock through their lives, this group of friends begins to unravel, and dangerous secrets are revealed one by one. When Alice begins to notice things amiss in her own apartment, the tension breaks out as it occurs to her that she is not the only person with a key, and she may not get a chance to change the locks. Jane Smiley applies her distinctive rendering of time, place, and the enigmatic intricacies of personal relationships to the twists and turns of suspense. The result is a thriller that will keep readers guessing up to its final, shocking conclusion.

The Asia-Paci?c region has emerged in recent years as one of the fastest g- wing regions in the world in the use of Web technologies as well as in making signi?cant contributions to WWW research and development. Since the ?rst Asia-Paci?c Web conference in 1998, APWeb has continued to provide a forum for researchers, professionals, and industrial practitioners from around the world to share their rapidly evolving knowledge and to report new advances in WWW technologies and applications. APWeb 2004 received an overwhelming 386 full-paper submissions, including 375 research papers and 11 industrial papers from 20 countries and regions: A- tralia,Canada,China,France,Germany,Greece,HongKong,India,Iran,Japan, Korea, Norway, Singapore, Spain, Switzerland, Taiwan, Turkey, UK, USA, and Vietnam. Each submission was carefully reviewed by three members of the p- gram committee. Among the 386 submitted papers, 60 regular papers, 24 short papers, 15 poster papers, and 3 industrial papers were selected to be included in the proceedings. The selected papers cover a wide range of topics including Web services, Web intelligence, Web personalization, Web query processing, Web - ching, Web mining, text mining, data mining and knowledge discovery, XML database and query processing, work?ow management, E-commerce, data - rehousing, P2P systems and applications, Grid computing, and networking. The paper entitled “Towards Adaptive Probabilistic Search in Unstructured P2P - stems”, co-authored by Linhao Xu, Chenyun Dai, Wenyuan Cai, Shuigeng Zhou, and Aoying Zhou, was awarded the best APWeb 2004 student paper.
