The Web has become the world’s largest database, with search being the main tool that allows organizations and individuals to exploit its huge amount of information. Search on the Web has been traditionally based on textual and structural similarities, ignoring to a large degree the semantic dimension, i.e., understanding the meaning of the query and of the document content. Combining search and semantics gives birth to the idea of semantic search. Traditional search engines have already advertised some semantic dimensions. Some of them, for instance, can enhance their generated result sets with documents that are semantically related to the query terms even though they may not include these terms. Nevertheless, the exploitation of the semantic search has not yet reached its full potential. In this book, Roberto De Virgilio, Francesco Guerra and Yannis Velegrakis present an extensive overview of the work done in Semantic Search and other related areas. They explore different technologies and solutions in depth, making their collection a valuable and stimulating reading for both academic and industrial researchers. The book is divided into three parts. The first introduces the readers to the basic notions of the Web of Data. It describes the different kinds of data that exist, their topology, and their storing and indexing techniques. The second part is dedicated to Web Search. It presents different types of search, like the exploratory or the path-oriented, alongside methods for their efficient and effective implementation. Other related topics included in this part are the use of uncertainty in query answering, the exploitation of ontologies, and the use of semantics in mashup design and operation. The focus of the third part is on linked data, and more specifically, on applying ideas originating in recommender systems on linked data management, and on techniques for the efficiently querying answering on linked data.

As the complexity of today’s networked computer systems grows, they become increasingly difficult to understand, predict, and control. Addressing these challenges requires new approaches to building these systems. Adaptive, Dynamic, and Resilient Systems supplies readers with various perspectives of the critical infrastructure that systems of networked computers rely on. It introduces the key issues, describes their interrelationships, and presents new research in support of these areas. The book presents the insights of a different group of international experts in each chapter. Reporting on recent developments in adaptive systems, it begins with a survey of application fields. It explains the requirements of such fields in terms of adaptation and resilience. It also provides some abstract relationship graphs that illustrate the key attributes of distributed systems to supply you with a better understanding of these factors and their dependencies. The text examines resilient adaptive systems from the perspectives of mobile, infrastructure, and enterprise systems and protecting critical infrastructure. It details various approaches for building adaptive, dynamic, and resilient systems—including agile, grid, and autonomic computing; multi-agent-based and biologically inspired approaches; and self-organizing systems. The book includes many stories of successful applications that illustrate a diversified range of cutting-edge approaches. It concludes by covering related topics and techniques that can help to boost adaptation and resilience in your systems.

The Missing Link to Toyota-Style Success—LEAN LEADERSHIP Winner of the 2012 Shingo Research and Professional Publications Award “This great book reveals the secret ingredient to lean success: lean leadership. Not only is it a pleasure to read, but it is also deep and enlightening. This book is an absolute must-read for anyone interested in lean: it’s both an eye opener and a game changer.” —Michael Ballé, Ph.D., coauthor of The Gold Mine and The Lean Manager “This will immediately be recognized as the most important book ever published to understand and guide ‘True North Lean’ and the goal of perpetual business excellence.” —Ross E. Robson, President and CEO, DnR Lean, LLC, and the original Director of The Shingo Prize “An excellent book that will shape leadership development for decades to come.” —Karen Martin, Principal, Karen Martin & Associates, and author of The Kaizen Event Planner About the Book: TOYOTA. The name signifies greatness— world-class cars and game-changing business thinking. One key to the Toyota Motor Company’s unprecedented success is its famous production system and its lesser-known product development program. These strategies consider the end user at every turn and have become the model for the global lean business movement. All too often, organizations adopting lean miss the most critical ingredient—lean leadership. Toyota makes enormous investments in carefully selecting and intensively developing leaders who fit its unique philosophy and culture. Thanks to the company’s lean leadership approach, explains Toyota Way author Jeffrey Liker and former Toyota executive Gary Convis, the celebrated carmaker has set into motion a drive for continuous improvement at all levels of its business. This has allowed for: Constant growth: Toyota increased profitability for 58 consecutive years—slowing down only in the face of 2008’s worldwide financial difficulties, the recall crisis, and the worst Japanese earthquake of the century. Unstoppable inventiveness: Toyota’s approach to innovative thinking and problem solving has resulted in top industry ratings and incredible customer satisfaction, while allowing the company to weather these three crises in rapid succession and to come out stronger. Strong branding and respect: Toyota’s reputation was instrumental in the company’s ability to withstand the recalls-driven media storm of 2010. But what looked to some to be a sinking ship is once again running under a full head of steam. Perhaps the Toyota culture had weakened, but lean leadership was the beacon that showed the way back. In fact, writes Liker, the company is “as good and perhaps a better model for lean leadership than it ever has been.” of innovation and growth. Yet, Industry Week reports that just 2 percent of companies using lean processes can likewise claim to have had long-term success. What the other 98 percent lack is unified leadership with a common method and philosophy. If you want to get lean, you have to take it to the leadership level. The Toyota Way to Lean Leadership shows you how.

In this new collection of essays, Andrew Feenberg argues that conflicts over the design and organization of the technical systems that structure our society shape deep choices for the future. A pioneer in the philosophy of technology, Feenberg demonstrates the continuing vitality of the critical theory of the Frankfurt School. He calls into question the anti-technological stance commonly associated with its theoretical legacy and argues that technology contains potentialities that could be developed as the basis for an alternative form of modern society. Feenberg's critical reflections on the ideas of Jürgen Habermas, Herbert Marcuse, Jean-François Lyotard, and Kitaro Nishida shed new light on the philosophical study of technology and modernity. He contests the prevalent conception of technology as an unstoppable force responsive only to its own internal dynamic and politicizes the discussion of its social and cultural construction. This argument is substantiated in a series of compelling and well-grounded case studies. Through his exploration of science fiction and film, AIDS research, the French experience with the "information superhighway," and the Japanese reception of Western values, he demonstrates how technology, when subjected to public pressure and debate, can incorporate ethical and aesthetic values.

Nationwide, more and more entrepreneurs are committing themselves to creating and running "third places," also known as "great good places." In his landmark work, The Great Good Place, Ray Oldenburg identified, portrayed, and promoted those third places. Now, more than ten years after the original publication of that book, the time has come to celebrate the many third places that dot the American landscape and foster civic life. With 20 black-and-white photographs, Celebrating the Third Place brings together fifteen firsthand accounts by proprietors of third places, as well as appreciations by fans who have made spending time at these hangouts a regular part of their lives. Among the establishments profiled are a shopping center in Seattle, a three-hundred-year-old tavern in Washington, D.C., a garden shop in Amherst, Massachusetts, a coffeehouse in Raleigh, North Carolina, a bookstore in Traverse City, Michigan, and a restaurant in San Francisco.
