Informationen zum Autor Ian H. Witten is a professor of computer science at the University of Waikato in New Zealand. He directs the New Zealand Digital Library research project. His research interests include information retrieval, machine learning, text compression, and programming by demonstration. He received an MA in Mathematics from Cambridge University, England; an MSc in Computer Science from the University of Calgary, Canada; and a PhD in Electrical Engineering from Essex University, England. He is a fellow of the ACM and of the Royal Society of New Zealand. He has published widely on digital libraries, machine learning, text compression, hypertext, speech synthesis and signal processing, and computer typography. He has written several books, the latest being Managing Gigabytes (1999) and Data Mining (2000), both from Morgan Kaufmann. Professor Gori's research interests are in the field of artificial intelligence, with emphasis on machine learning and game playing. He is a co-author of the book “Web Dragons: Inside the myths of search engines technologies,? Morgan Kauffman (Elsevier), 2007. He was the Chairman of the Italian Chapter of the IEEE Computational Intelligence Society, and the President of the Italian Association for Artificial Intelligence. He is in the list of top Italian scientists kept by VIAAcademy (http://www.topitalianscientists.org/top_italian_scientists.aspx). Dr. Gori is a fellow of the IEEE, ECCAI, and IAPR. A recent Forrester Research survey found more users had used a search engine in the last four weeks than had used email, making web search the Internet's new killer app. And while we know nothing about search engine technology of the particular flavor of engine we use, we nevertheless count on the authority and trustworthiness of the information we receive. In fact, we are so trusting of it that we use the web to build our own knowledge structure--and we do it in public, too, rather than in the privacy of our own library. In the meantime we are witnessing a radical convergence of online and print information, and of commercial and non-commercial sources, as new online distribution initiatives are begun every day. This book introduces the changing ways in which we locate information on the Web, and how what is presented to us as a result of our search is determined. It is critical, in part, in its presentation of the problems of web spam and of the current centralized approach to web searching--and presents solutions that give power to users rather than the advertisers and the search engines. ...

Report
"It is not a resource on how search engines work, but rather what ideas and ideals have been realized in the development of search engines, the political and human challenges they face and problems and opportunities they present to humans and to the nature of knowledge and information. The book is written in a clear, simple fashion, making it accessible to all readers. The broad swath it cuts, however, does not detract from its use as an academic course resource." --Choice, June 2007
"If you've ever searched the web for information and wondered what's going on behind that query box, I recommend you read Web Dragons. It puts Internet search engines in context-part of a legacy of information access dating back thousands of years. It explains in plain language how search engines work, and points out potential pitfalls that thoughtful searchers should consider. Web Dragons is clear and engaging. Given the amount of time and trust we all invest in search engines, if you pay attention to the web I highly recommend redirecting some of that attention to this book." --Craig Nevill-Manning, Engineering Director, Google
"Search technology is changing the way people understand and interact with the world. Web Dragons takes a revealing look at the evolution of search and how it will shape the future of information technology." --Prabhakar Raghavan, Head of Yahoo! Research
"Witten, Gori and Numerico steadily bring the web into sharper and sharper focus. A daunting expanse is revealed to have structure. The structure enables the knowledgeable to navigate it to their benefit and allows the unscrupulous or careless to create pitfalls and traps. Search engines will be critical tools for most people living today. What could be more important than understanding how these technologies work and where they are going?" --Jonathan Grudin, Microsoft Research
