Internet and web technology penetrates many aspects of our daily life. Its importance as a medium for business transactions will grow exponentially during the next few years. In terms of the involved market volume, the B2B area will hereby be the most interesting area. Also, it will be the place, where the new technology will lead to drastic changes in established customer relationships and business models. In an era where open and flexible electronic commerce provides new types of services to its users, simple 1-1 connections will be replaced by n-m relationships between customers and vendors.
This new flexibility in electronic trading will generate serious challenges. The main problem stems from the heterogeneity of information descriptions used by vendors and customers, creating problems in both manual trading and in direct 1-1 electronic trading. In the case of B2B market places, it becomes too serious to be neglected. Product descriptions, catalog formats and business documents are often unstructured and non-standardized. Intelligent solutions that mechanize the structuring, standardizing, aligning, and personalizing process are a key requisite for successfully overcoming the current bottlenecks of B2B electronic commerce while enabling its further growth. Intelligent Information Integration in B2B Electronic Commerce discusses the main problems of information integration in this area and sketches several technological solution paths.
Intelligent Information Integration in B2B Electronic Commerce is designed to meet the needs of a professional audience composed of researchers and practitioners in industry and graduate level students in Computer Science.

 The dynamics of the digital economy in the US, Europe and Japan are rather different. Some EU countries come close to the USA as the leading OECD country in the new economy, but Japan faces particular problems in catching-up digitally. Information and communication technology will affect productivity growth, production, the financial system and trade. Setting adequate rules for the digital economy - at the national and international level - is a key challenge for industrialized countries. Moreover, cultural and organizational challenges will also have to be met.

After the dramatic failures of the dot coms in 2000 and 2001, many observers were quick to report on the death of electronic commerce. Investor confidence sagged, stock prices of technology firms in nearly all of the related sectors suffered. In reality, the picture is not nearly as dismal as the press would have us believe. E-commerce is not dead, but it has moved beyond its overhyped beginning stage. This book is an effort to sort through the hype, providing a realistic assessment of the state of electronic commerce today, and the important areas of opportunity and challenge for tomorrow. The book sees all kind of developments where e-business is becoming an integral part of 'traditional' business processes, with special emphasis on practical and policy importance. E-commerce scholars from a number of disciplines and countries contribute to assess the impact of the dot com bust and the current state of e-commerce.

Classifying objects into categories at different granularity levels, establishing links between known objects, and discovering clues between known and unknown objects are essential for new-generation semantic data models. This book introduces the Resource Space Model (RSM), which effectively organizes and correctly manages resources by normalizing classification semantics. This volume presents basic models of RSM and the Semantic Link Network (SLN), the relationship between the two, and an approach to integrating the two models and exploring their semantic-rich interconnection. Also detailed is a comprehensive theory of query operations on RSM and extensive coverage of the distributed RSM in parallel with the distributed relational database systems. This text is sure to be considered a substantial contribution to the field of Knowledge Grid by researchers in the areas of web, semantic web, and decentralized data engineering, as well as the emerging semantic and knowledge grid arena.

With the daily addition of million documents and new users, there is no doubt that the World Wide Web (WWW or Web shortly) is still expanding its global information infrastructure. Thanks to low-cost wireless technology, the Web is no more limited to homes or offices, but it is simply everywhere. The Web is so large and growing so rapidly that the 40 million page "WebBase" repository of Inktomi corresponds to only about 4% of the estimated size of the publicly indexable Web as of January 2000 and there is every reason to believe these numbers will all swell significantly in the next few years. This unrestrainable explosion is not bereft of troubles and drawbacks, especially for inexpert users. Probably the most critical problem is the effectiveness of Web search engines: though the Web is rich in providing numerous services, the primary use of the Internet falls in emails and information retrieval activities. Focusing in this latter, any user has felt the frustrating experience to see as result of a search query overwhelming numbers of pages that satisfy the query but that are irrelevant to the user.

This book presents a specific and unified approach framework to three major components: Search Engines Performance, Link Analysis, and User 's Web Behavior. The book can be used by researchers in the fields of information sciences, engineering (especially software), computer science, statistics and management, who are looking for a unified theoretical approach to finding relevant information on the WWW and a way of interpreting it from a data perspective to a user perspective.

Once the basic idea of hypertext had spread rapidly throughout the world via the Internet, the reception of hypertexts soon became subject of empirical research among psychologists, cognitive scientists, and educational researchers. As easy to use software for the writing of hypertexts (HTML editors) is now broadly available, there are no longer any technical obstacles for the use of hypertext production in teaching and learning. This book presents and analyses the learning effects that can be anticipated from the production of hypertexts. It includes laboratory experiments, studies on the production of hypertexts in the context of educational institutions, and reports on software environments designed for the production of hypertext. It includes theoretical, empirically and developmentally oriented contributions. The first three chapters link up directly with research on traditional writing while addressing aspects of the interaction between content and rhetoric during hypertext writing. The next three chapters focus on cooperative learning of students in and through the production of hypertexts. The following two chapters look at new technological possibilities, namely, a software environment for transforming textbooks into personalized hypertexts and the design of hypervideos. The final chapter discusses potential methods for further research.
