The standards for usability and interaction design for Web sites and software are well known. While not everyone uses those standards, or uses them correctly, there is a large body of knowledge, best practice, and proven results in those fields, and a good education system for teaching professionals "how to." For the newer field of Web application design, however, designers are forced to reuse the old rules on a new platform. This book provides a roadmap that will allow readers to put complete working applications on the Web, display the results of a process that is running elsewhere, and update a database on a remote server using an Internet rather than a network connection.

While e-commerce has experienced meteoric growth recently, security risks have similarly grown in scope and magnitude. Three major factors have driven the security risks in e-commerce: the growing reliance on the electronic medium for a company's core business, the growing complexity of the software systems needed to support e-commerce, and the value of the digital assets brought online to an inherently insecure medium - the Internet. While security has long been a primary concern in e-commerce, more recently privacy has also grown in importance to consumers. Many of the same Internet technologies that make e-commerce possible also make it possible to create detailed profiles of an individual's purchases, to spy on individual Web usage habits, and even to peer into confidential files that reside on an individual's machine. E-Commerce Security and Privacy is the first volume to pull together leading researchers and practitioners in diverse areas of computer science and software engineering to explore their technical innovations to problems in security and privacy in e-commerce. The information is drawn from selected papers presented at the first Workshop on Security and Privacy in E-Commerce (WSPEC'00) held in Athens, Greece, November 4, 2000. As such, E-Commerce Security and Privacy introduces both practitioners and researchers to innovations in secure and private e-commerce. Practitioners will gain great insight from the case studies, and researchers will learn about state-of-the-art protocols in secure and private e-commerce that will serve as the basis for future innovations in applied e-commerce technologies. E-Commerce Security and Privacy is suitable as a secondary text for agraduate level course, and as a reference for researchers and practitioners in industry.

The Web is growing at an astounding pace surpassing the 8 billion page mark. However, most pages are still designed for human consumption and cannot be processed by machines. This book provides a well-paced introduction to the Semantic Web. It covers a wide range of topics, from new trends (ontologies, rules) to existing technologies (Web Services and software agents) to more formal aspects (logic and inference). It includes: real-world (and complete) examples of the application of Semantic Web concepts; how the technology presented and discussed throughout the book can be extended to other application areas.

The Social Web (including services such as MySpace, Flickr, last.fm, and WordPress) has captured the attention of millions of users as well as billions of dollars in investment and acquisition. Social websites, evolving around the connections between people and their objects of interest, are encountering boundaries in the areas of information integration, dissemination, reuse, portability, searchability, automation and demanding tasks like querying. The Semantic Web is an ideal platform for interlinking and performing operations on diverse person- and object-related data available from the Social Web, and has produced a variety of approaches to overcome the boundaries being experienced in Social Web application areas.

After a short overview of both the Social Web and the Semantic Web, Breslin et al. describe some popular social media and social networking applications, list their strengths and limitations, and describe some applications of Semantic Web technology to address their current shortcomings by enhancing them with semantics. Across these social websites, they demonstrate a twofold approach for interconnecting the islands that are social websites with semantic technologies, and for powering semantic applications with rich community-created content. They conclude with observations on how the application of Semantic Web technologies to the Social Web is leading towards the "Social Semantic Web" (sometimes also called "Web 3.0"), forming a network of interlinked and semantically-rich content and knowledge.

The book is intended for computer science professionals, researchers, and graduates interested in understanding the technologies and research issues involved in applying Semantic Web technologies to social software. Practitioners and developers interested in applications such as blogs, social networks or wikis will also learn about methods for increasing the levels of automation in these forms of Web communication.

This visionary book presents an interdisciplinary and cogent approach to the issue of Internet governance and control. By examining five critical areas in which the tension between freedom and control is most palpable--fair competition and open access, free expression, intellectual property, privacy rights, and security--Spinello guides the reader on a tour of the emerging body of law and public policy that has attempted to control the anarchy of cyberspace. In so doing, he defends the credo of Internet self-regulation, asserting that the same powerful and flexible architectures that created the Internet as we know it today can be relied upon to aid the private sector in arriving at a workable, decentralized regulatory regime. Except in certain circumstances that require government involvement, self-regulation is not only viable but is a highly preferred alternative to the forced uniformity that centralized structures tend to impose.

Beginning with an exploration of the Internet's most important values, including universality, free expression, and open access, as well as its promise as a democratizing force, Spinello considers how we can most effectively preserve those values and fulfill that promise while curtailing the social harms that vex Internet users. How do we arrive at the right mixture of technology and policy so that the Internet does not lose its promise as a liberating technology? In examining this question, Spinello evaluates such architectures of control as filters and rights management protocols, which attempt to keep out unwanted information and protect intellectual property, respectively. He explores how these and other technologies can be designed and used responsibly so that online social order can be sustained with a minimal amount of government intervention.

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.
