J.-E. Dubois and N. Gershon This book was inspired by the Symposium on "Communications and Computer Aided Systems" held at the 14th International CODATA Conference in September 1994 in Chambery, France. It was conceived and influenced by the discussions at the symposium and most of the contributions were written following the Conference. This is the first comprehensive book, published in one volume, of issues concerning the challenges and the vital impact of the information revolution (including the Internet and the World Wide Web) on science and technology. Topics concerning the impact of the information revolution on science and technology include: • Dramatic improvement in sharing of data and information among scientists and engineers around the world • Collaborations (on-line and off-line) of scientists and engineers separated by distance . • Availability of visual tools and methods to view, understand, search, and share information contained in data • Improvements in data and information browsing, search and access and • New ways of publishing scientific and technological data and information. These changes have dramatically modified the way research and development in science and technology are being carried out. However, to facilitate this information flow nationally and internationally, the science and technology communities need to develop and put in place new standards and policies and resolve some legal issues.

This volume is based on the contributions to the International Workshop on the Web and Databases (WebDB’98), held in Valencia, Spain, March 27 and 28, 1998, in conjunction with the Sixth International Conference on Extending Database Technology (EDBT’98). In response to the workshop call for papers, 37 manuscripts were submitted to the program committee. The review process was conducted entirely by- mail. While the quality of submissions was generally high, only 16 papers could be accepted for presentation within the limited time allowed by the workshop schedule. Authors of workshop papers were invited to submit extended versions oftheirpapersforpublicationinthesepost-workshopproceedings.The13papers appearing in this volume were submitted and selected after a second round of reviews. We would like to thank the program committee of WebDB’98, all those who submitted their work, all additional reviewers, and the conference o?cials of EBDT’98 for their invaluable support. Special thanks go to Paolo Merialdo, who actively participated in the organization of the workshop.

Mining the World Wide Web: An Information Search Approach explores the concepts and techniques of Web mining, a promising and rapidly growing field of computer science research. Web mining is a multidisciplinary field, drawing on such areas as artificial intelligence, databases, data mining, data warehousing, data visualization, information retrieval, machine learning, markup languages, pattern recognition, statistics, and Web technology. Mining the World Wide Web presents the Web mining material from an information search perspective, focusing on issues relating to the efficiency, feasibility, scalability and usability of searching techniques for Web mining. Mining the World Wide Web is designed for researchers and developers of Web information systems and also serves as an excellent supplemental reference to advanced level courses in data mining, databases and information retrieval.

With the development of the World-Wide Web, data management problems have branched out from the traditional framework in which tabular data is processed under the strict control of an application, and address today the rich variety of information that is found on the Web, considering a variety of ?exible envir- ments under which such data can be searched, classi ed , and processed. Da- base systems are coming forward today in a new role as the primary backend for the information provided on the Web. Most of today’s Web accesses trigger some form of content generation from a database, while electronic commerce often triggers intensive DBMS-based applications. The research community has begun to revise data models, query languages, data integration techniques, - dexes, query processing algorithms, and transaction concepts in order to cope with the characteristics and scale of the data on the Web. New problems have been identi ed , among them goal-oriented information gathering, management of semi-structured data, or database-style query languages for Web data, to name just a few. The International Workshop on the Web and Databases (WebDB) is a series of workshops intended to bring together researchers interested in the interaction between databases and the Web. This year’s WebDB 2000 was the third in the series, and was held in Dallas, Texas, in conjunction with the ACM SIGMOD International Conference on Management of Data.

The past 50 years have witnessed a revolution in computing and related communications technologies. The contributions of industry and university researchers to this revolution are manifest; less widely recognized is the major role the federal government played in launching the computing revolution and sustaining its momentum. Funding a Revolution examines the history of computing since World War II to elucidate the federal government's role in funding computing research, supporting the education of computer scientists and engineers, and equipping university research labs. It reviews the economic rationale for government support of research, characterizes federal support for computing research, and summarizes key historical advances in which government-sponsored research played an important role. Funding a Revolution contains a series of case studies in relational databases, the Internet, theoretical computer science, artificial intelligence, and virtual reality that demonstrate the complex interactions among government, universities, and industry that have driven the field. It offers a series of lessons that identify factors contributing to the success of the nation's computing enterprise and the government's role within it.

This book is about using the Internet as a teaching tool. It starts with the psychology of the learner and looks at how best to fit technology to the student, rather than the other way around. The authors include leading authorities in many areas of psychology, and the book takes a broad look at learners as people. Thus, it includes a wide range of materials from how the eye "reads" moving graphs on a Web page to how people who have never met face-to-face can interact on the Internet and create "communities" of learners. The book considers many Internet technologies, but focuses on the World Wide Web and new "hybrid" technologies that integrate the Web with other communications technologies. This book is essential to researchers is psychology and education who are interested in learning. It is also used in college and graduate courses in departments of psychology and educational psychology. Teachers and trainers at any level who are using technology in their teaching (or thinking about it) find this book very useful. Key Features * Distinguished authors with considerable expertise in their fields * Broad "intra-disciplinary" perspective on learning and teaching on the Web * Focus on the Web and emerging Web-based technologies * Special attention to conducting educational research on-line * Emphasis on the Social and Psychological Context * Analyses of effective Web-based learning resources * Firmly grounded in contemporary psychological research and theory

This text provides an explanation of CGI and related techniques for people who want to provide their own information servers on the Web. It explains the value of CGI and how it works, and looks at the subtle details of programming. The accompanying CD-ROM
