Information retrieval technology has been central to the success of the web. The goal of information retrieval is to provide users with those documents that will satisfy their information need. With the large volume of data available in the web, retrieving relevant information becomes a difficult task. The Semantic Web area has seen rapid development nowadays. Semantic Web also offers a powerful practical approach to gain over multitude of information and services. It requires new data representations that improve our ability to capture and share knowledge. This book explores the perspective of information retrieval in semantic web which is a powerful way to access, use and share information.

This study was conceived with the aim of investigating the availability and utilization of information and communication technology for accessing health information by medical professionals in Kenya. The study started from the premise that access to relevant information and knowledge is critical to the delivery of effective healthcare services. Although most of the health information is continuously being delivered electronically, many healthcare professionals in developing countries including Kenya are disadvantaged because of limited access to and use of ICT. The research was exploratory in nature and used Kenyatta National Hospital as a case study.
This book examines the effectiveness of communication between chief information officer (CIO) and chief executive officer (CEO) and its impact on the role of information technology (IT) in an organization. The book is empirically based on interviews with CIO/CEO pairs from twelve organizations in the manufacturing and retail industries. It examines how CIOs and CEOs can achieve effectiveness in their communication, including insights into antecedents and consequences of communication effectiveness. Based on the interview data the authors develop a CIO/CEO communication model with which CIOs and CEOs can gain new insights into the efficiency of their interactions, likely resulting in higher levels of shared understanding regarding the role of IT in their organization.
Despite its explosive growth over the last decade, the Web remains essentially a tool to allow humans to access information. Semantic Web technologies like RDF, OWL and other W3C standards aim to extend the Web´s capability through increased availability of machine-processable information. Davies, Grobelnik and Mladenic have grouped contributions from renowned researchers into four parts: technology; integration aspects of knowledge management; knowledge discovery and human language technologies; and case studies. Together, they offer a concise vision of semantic knowledge management, ranging from knowledge acquisition to ontology management to knowledge integration, and their applications in domains such as telecommunications, social networks and legal information processing. This book is an excellent combination of fundamental research, tools and applications in Semantic Web technologies. It serves the fundamental interests of researchers and developers in this field in both academia and industry who need to track Web technology developments and to understand their business implications.
Communications and personal information that are posted online are usually accessible to a vast number of people. Yet when personal data exist online, they may be searched, reproduced and mined by advertisers, merchants, service providers or even stalkers. Many users know what may happen to their information, while at the same time they act as though their data are private or intimate. They expect their privacy will not be infringed while they willingly share personal information with the world via social network sites, blogs, and in online communities. The chapters collected by Trepte and Reinecke address questions arising from this disparity that has often been referred to as the privacy paradox. Works by renowned researchers from various disciplines including psychology, communication, sociology, and information science, offer new theoretical models on the functioning of online intimacy and public accessibility, and propose novel ideas on the how and why of online privacy. The contributing authors offer intriguing solutions for some of the most pressing issues and problems in the field of online privacy. They investigate how users abandon privacy to enhance social capital and to generate different kinds of benefits. They argue that trust and authenticity characterize the uses of social network sites. They explore how privacy needs affect users´ virtual identities. Ethical issues of privacy online are discussed as well as its gratifications and users´ concerns. The contributors of this volume focus on the privacy needs and behaviors of a variety of different groups of social media users such as young adults, older users, and genders. They also examine privacy in the context of particular online services such as social network sites, mobile internet access, online journalism, blogs, and micro-blogs. In sum, this book offers researchers and students working on issues related to internet communication not only a thorough and up-to-date treatment of online privacy and the social web. It also presents a glimpse of the future by exploring emergent issues concerning new technological applications and by suggesting theory-based research agendas that can guide inquiry beyond the current forms of social technologies.
Sensor Data Fusion is the process of combining incomplete and imperfect pieces of mutually complementary sensor information in such a way that a better understanding of an underlying real-world phenomenon is achieved. Typically, this insight is either unobtainable otherwise or a fusion result exceeds what can be produced from a single sensor output in accuracy, reliability, or cost. This book provides an introduction Sensor Data Fusion, as an information technology as well as a branch of engineering science and informatics. Part I presents a coherent methodological framework, thus providing the prerequisites for discussing selected applications in Part II of the book. The presentation mirrors the author´s views on the subject and emphasizes his own contributions to the development of particular aspects. With some delay, Sensor Data Fusion is likely to develop along lines similar to the evolution of another modern key technology whose origin is in the military domain, the Internet. It is the author´s firm conviction that until now, scientists and engineers have only scratched the surface of the vast range of opportunities for research, engineering, and product development that still waits to be explored: the Internet of the Sensors.
Follow step-by-step guidance to craft a successful security program. You will identify with the paradoxes of information security and discover handy tools that hook security controls into business processes.

Die ´´Einführung in die Kybernetik´´ ist eines der Standardwerke der jungen Wissenschaft Kybernetik, nicht zuletzt durch des Autors didaktisches Geschick der Grundlagenvermittlung. Ashby vermeidet es, für den Laien unnötig verwirrende Bereiche der Elektronik und der höheren Mathematik in seine Einführung einzubeziehen und verwendet satt dessen allgemeinverständliche Beispiele aus dem Alltag. Im ersten Teil geht es um Systeme im allgemeinen, um ihre schematische Darstellung durch Transformation, um Stabilität, Unabhängigkeit und Rückkoppelung. Im zweiten Teil des Buches befaßt sich Ashby mit ´´Information´´ im Zusammenhang mit der grundlegenden Theorie Shannons. Zur Erläuterung von Information und Codierung etc. werden zahlreiche Beispiele aus dem Bereich biologischer Forschung herangezogen. Der dritte Teil zeigt Verwendungsmöglichkeiten von Mechanismen und Information für die Regelung und Kontrolle von Systemen. Dabei geht es ebenso um natürliche Systeme (wie das menschliche Hirn), die Gegenstand der Physiologie sind, wie auch um künstliche, das heißt um die Konstruktion von Maschinen, die in ihrer Funktion der des Hirns vergleichbar sind.
