This book presents a review of traditional context-aware computing research, identifies its limitations in developing social context-aware pervasive systems, and introduces a new technology framework to address these limitations. Thus, this book provides a good reference for developments in context-aware computing and pervasive social computing. It examines the emerging area of pervasive social computing, which is a novel collective paradigm derived from pervasive computing, social media, social networking, social signal processing and multimodal human-computer interaction. This book offers a novel approach to model, represent, reason about and manage different types of social context. It shows how users' social context information can be acquired from different online social networks such as Facebook, LinkedIn, Twitter and Google Calendar. It further presents the use of social context information in developing innovative smart mobile applications to assist users in their daily life. The mix of both theoretical and applied research results makes this book attractive to a variety of readers from both academia and industry. This book provides a new platform for implementing different types of socially-aware mobile applications. The platform hides the complexity of managing social context, and thus provides essential support to application developers for the development of socially-aware applications. The book contains detailed descriptions of how the underlying platform has been implemented using available technologies such as ontology and rule engines, and how this platform can be used to develop socially-aware mobile applications using two exemplar applications. The book also presents evaluations of the proposed platform and applications using real-world data from Facebook, LinkedIn and Twitter. Therefore, this book is a syndication of scientific research with practical industrial applications, making it useful to researchers as well as to software engineers.

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.

Correcting the Great Mistake People often mistake one thing for another. That's human nature. However, one would expect the leaders in a particular ?eld of endeavour to have superior ab- ities to discriminate among the developments within that ?eld. That is why it is so perplexing that the technology elite - supposedly savvy folk such as software developers, marketers and businessmen - have continually mistaken Web-based graphics for something it is not. The ?rst great graphics technology for the Web, VRML, has been mistaken for something else since its inception. Viewed variously as a game system, a format for architectural walkthroughs, a platform for multi-user chat and an augmentation of reality, VRML may qualify as the least understood invention in the history of inf- mation technology. Perhaps it is so because when VRML was originally introduced it was touted as a tool for putting the shopping malls of the world online, at once prosaic and horrifyingly mundane to those of us who were developing it. Perhaps those ?rst two initials,"VR,"created expectations of sprawling, photorealistic f- tasy landscapes for exploration and play across the Web. Or perhaps the magnitude of the invention was simply too great to be understood at the time by the many, ironically even by those spending the money to underwrite its development. Regardless of the reasons, VRML suffered in the mainstream as it was twisted to meet unintended ends and stretched far beyond its limitations.

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.

DSSSL (Document Style Semantics and Specification Language) is an ISO standard (ISO/IEC 10179: 1996) published in the year 1996. DSSSL is a standard of the SGML family (Standard Generalized Markup Language, ISO 8879:1986), whose aim is to establish a processing model for SGML documents. For a good understanding of the SGML standard, many books exist including Author's guide[BryanI988] and The SGML handbook[GoldfarbI990]. A DSSSL document is an SGML document, written with the same rules that guide any SGML document. The structure of a DSSSL document is explained in Chapter 2. DSSSL is based, in part, on scheme, a standard functional programming language. The DSSSL subset of scheme along with the procedures supported by DSSSL are explained in Chapter 3. The DSSSL standard starts with the supposition of a pre-existing SGML document, and offers a series of processes that can be performed on it: * Groves The first process that is performed on an SGML document in DSSSL is always the analysis of the document and the creation of a grove. The DSSSL standard shares many common characteristics with another standard of the SGML family, HyTime (ISO/IEC 10744). These standards were developed in parallel, and their developers designed a common data model, the grove, that would support the processing needs of each standard.
