All day, every day, Americans seek information. We research major purchases. We check news and sports. We visit government Web sites for public information and turn to friends for advice about our everyday lives. Although the Internet influences our information-seeking behavior, we gather information from many sources: family and friends, television and radio, books and magazines, experts and community leaders.
The ability to manage knowledge has become increasingly important in today’s knowledge economy. Knowledge is considered a valuable commodity, embedded in products and in the tacit knowledge of highly mobile individual employees. Knowledge management (KM) represents a deliberate and systematic approach to cultivating and sharing an organization’s knowledge base. It is a highly multidisciplinary field that encompasses both information technology and intellectual capital.
Cartographic maps have guided our explorations for centuries, allowing us to navigate the world. Science maps have the potential to guide our search for knowledge in the same way, helping us navigate, understand, and communicate the dynamic and changing structure of science and technology. Allowing us to visualize scientific results, science maps help us make sense of the avalanche of data generated by scientific research today.
Information retrieval is the foundation for modern search engines. This text offers an introduction to the core topics underlying modern search technologies, including algorithms, data structures, indexing, retrieval, and evaluation. The emphasis is on implementation and experimentation; each chapter includes exercises and suggestions for student projects. Wumpus--a multiuser open-source information-retrieval system developed by one of the authors and available online--provides model implementations and a basis for student work.
The healthcare industry has been slow to join the information technology revolution; handwritten records are still the primary means of organizing patient care. Concerns about patient privacy, the difficulty of developing appropriate computing tools and information technology, high costs, and the resistance of some physicians and nurses have hampered the use of technology in health care. In 2009, the U.S. government committed billions of dollars to health care technology. Many questions remain, however, about how to deploy these resources.
Advances in information and communication technology are transforming the way scholarly research is conducted across all disciplines. The use of increasingly powerful and versatile computer-based and networked systems promises to change research activity as profoundly as the mobile phone, the Internet, and email have changed everyday life. This book offers a comprehensive and accessible view of the use of these new approaches--called “e-Research”--and their ethical, legal, and institutional implications.
Information retrieval in the age of Internet search engines has become part of ordinary discourse and everyday practice: "Google" is a verb in common usage. Thus far, more attention has been given to practical understanding of information retrieval than to a full theoretical account.
Service-Oriented Applications and Architectures (SOAs) have captured the interest of industry as a way to support business-to-business interaction, and the SOA market grew by $4.9 billion in 2005. SOAs and in particular service-oriented computing (SOC) represent a promising approach in the development of adaptive distributed systems. With SOC, applications can open themselves to services offered by third parties and accessed through standard, well-defined interfaces.
Service-Oriented Computing (SOC) promises a world of cooperating services loosely connected, creating dynamic business processes and agile applications that span organizations and platforms. As a computing paradigm, it utilizes services as fundamental elements to support rapid, low-cost development of distributed applications in heterogeneous environments. Realizing the SOC promise requires the design of Service-Oriented Architectures (SOAs) that enable the development of simpler and cheaper distributed applications.
In recent decades we have witnessed the creation of a communication system that promises unparalleled connectedness. And yet the optimistic dreams of Internet-enabled engagement and empowerment have faded in the face of widespread Internet commercialization. In Liberating Voices, Douglas Schuler urges us to unleash our collective creativity--social as well as technological--and develop the communication systems that are truly needed.
