As the Internet revolution continues to unfold and transform telecommunications, pressure is building for faster, less expensive, and more widely accessible broadband service. Such a development would facilitate improved and less expensive traditional applications such as voice telephony and web browsing. It would also enable new and useful applications such as Internet-based television, videoconferencing, and software distribution. Broadband has great potential to improve efficiency and productivity, even to improve national security in some cases. Broadband service and affordability, however, have consistently lagged well behind demand and progress in information technology, with damaging results. The Internet revolution remains incomplete and threatens to stagnate if the situation continues. In The Broadband Problem, economist and technology entrepreneur Charles H. Ferguson explains the causes and ramifications of this damaging bottleneck, and he offers suggestions on improving the current state of affairs. He asserts that current telecommunications law and policy have not provided sufficient levels of new entry, competition, and innovation in the local telecom market. The continuing dominance of ILECs (incumbent local exchange carriers) in that market impedes the healthy, and much-needed, development of an efficient broadband market. The result of these policy and market failures is inadequate technological progress, innovation, and productivity in advanced Internet services and telecommunication services generally. The broadband problem is holding us back, and thus must be addressed and solved. With this important volume, Charles Ferguson has contributed mightily to that mission.

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.

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.

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.

The Semantic Web aims at machine agents that thrive on explicitly specified semantics of content in order to search, filter, condense, or negotiate knowledge for their human users. A core technology for making the Semantic Web happen, but also to leverage application areas like Knowledge Management and E-Business, is the field of Semantic Annotation, which turns human-understandable content into a machine understandable form. This book reports on the broad range of technologies that are used to achieve this translation and nourish 3rd millennium applications. The book starts with a survey of the oldest semantic annotations, viz. indexing of publications in libraries. It continues with several techniques for the explicit construction of semantic annotations, including approaches for collaboration and Semantic Web metadata. One of the major means for improving the semantic annotation task is information extraction and much can be learned from the semantic tagging of linguistic corpora. In particular, information extraction is gaining prominence for automating the formerly purely manual annotation task - at least to some extent.An important subclass of information extraction tasks is the goal-oriented extraction of content from HTML and / or XML resources.

Private online digital currency systems offer people accessible, convenient, and inexpensive everyday financial tools outside of traditional bank-owned and operated platforms. Digital currency systems facilitate local and international fund transfers, online and offline payments, and simple cash-to-digital everyday financial products without the need for a conventional bank account of any retail bank product. Over the past several years, Bitcoin has grown into an efficient person-to-person and person-to-business payment system without the backing of any bank or financial institution. This phenomenon is producing a new level of an on- and offline commerce and a society much more attuned to digital currency systems. The Digital Currency Challenge details how new 2007-2008 U.S. legal issues surrounding digital currency products forced companies from the U.S. market and caused the Treasury Department to enact stricter regulations. Mullan profiles new and innovative present day digital currency systems, such as Bitcoin, and illustrates how software designers and monetary theorists use new technology to circumvent current U.S. regulations. This work also explains how new digital currency systems are not just software products, but tools providing financial freedom to people in countries all around the world.

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.

In this book, the authors first address the research issues by providing a motivating scenario, followed by the exploration of the principles and techniques of the challenging topics. Then they solve the raised research issues by developing a series of methodologies. More specifically, the authors study the query optimization and tackle the query performance prediction for knowledge retrieval. They also handle unstructured data processing, data clustering for knowledge extraction. To optimize the queries issued through interfaces against knowledge bases, the authors propose a cache-based optimization layer between consumers and the querying interface to facilitate the querying and solve the latency issue. The cache depends on a novel learning method that considers the querying patterns from individual's historical queries without having knowledge of the backing systems of the knowledge base. To predict the query performance for appropriate query scheduling, the authors examine the queries' structural and syntactical features and apply multiple widely adopted prediction models. Their feature modelling approach eschews the knowledge requirement on both the querying languages and system. To extract knowledge from unstructured Web sources, the authors examine two kinds of Web sources containing unstructured data: the source code from Web repositories and the posts in programming question-answering communities. They use natural language processing techniques to pre-process the source codes and obtain the natural language elements. Then they apply traditional knowledge extraction techniques to extract knowledge. For the data from programming question-answering communities, the authors make the attempt towards building programming knowledge base by starting with paraphrase identification problems and develop novel features to accurately identify duplicate posts. For domain specific knowledge extraction, the authors propose to use a clustering technique to separate knowledge into different groups. They focus on developing a new clustering algorithm that uses manifold constraints in the optimization task and achieves fast and accurate performance. For each model and approach presented in this dissertation, the authors have conducted extensive experiments to evaluate it using either public dataset or synthetic data they generated.

'Securing Web Services' investigates the security-related specifications that encompass message level security, transactions, and identity management.

Electronic commerce is here to stay. No matter how big the dot-com crisis was or how far the e-entrepreneurs' shares fell in the market, the fact remains that there is still confidence in electronic trading. At least it would appear that investors are confident in e-companies again. However, not only trust of venture capitalists is of importance--consumers also have to have faith in on-line business. After all, without consumers there is no e-business. Interacting lawyers, technicians and economists are needed to create a trustworthy electronic commerce environment. To achieve this environment, thorough and inter-disciplinary research is required and that is exactly what this book is about. Researchers of the project Enabling Electronic Commerce from the Dutch universities of Tilburg and Eindhoven have chosen a number of e-topics to elaborate on trust from their point of view. This volume makes clear that the various disciplines can and will play a role in developing conditions for trust and thus contribute to a successful electronic market.
