Information Retrieval (IR) has concentrated on the development of information management systems to support user retrieval from large collections of homogeneous textual material. A variety of approaches have been tried and tested with varying degrees of success over many decades of research. Hypertext (HT) systems, on the other hand, provide a retrieval paradigm based on browsing through a structured information space, following pre-defined connections between information fragments until an information need is satisfied, or appears to be. Information Retrieval and Hypertext addresses the confluence of the areas of IR and HT and explores the work done to date in applying techniques from one area, to the other leading to the development of `hypertext information retrieval' (HIR) systems. An important aspect of the work in IR/HT and in any user-centred information system is the emergence of multimedia information and such multimedia information is treated as an integral information type in this text. The contributed chapters cover the development of integrated hypertext information retrieval models, and the application of IR and HT techniques in hypertext construction and the approaches that can be taken in searching HIR systems. These chapters are complemented by two overview chapters covering, respectively, information retrieval and hypertext research and developments. Information Retrieval and Hypertext is important as it is the first text to directly address the combined searching/browsing paradigm of information discovery which is becoming so important in modern computing environments. It will be of interest to researchers and professionals working in a range of areas related to information discovery.
Modern science is under the greatest and most successful attack in recent history. An industry of denial, abetted by news media and "info-tainment" broadcasters more interested in selling controversy than presenting facts, has duped half the American public into rejecting the facts of climate science--an overwhelming body of rigorously vetted scientific evidence showing that human-caused, carbon-based emissions are linked to warming the Earth. The industry of climate science denial is succeeding: public acceptance has declined even as the scientific evidence for global warming has increased. It is vital that the public understand how anti-science ideologues, pseudo-scientists, and non-scientists have bamboozled them. We cannot afford to get global warming wrong--yet we are, thanks to deniers and their methods. The Inquisition of Climate Science is the first book to comprehensively take on the climate science denial movement and the deniers themselves, exposing their lack of credentials, their extensive industry funding, and their failure to provide any alternative theory to explain the observed evidence of warming. In this book, readers meet the most prominent deniers while dissecting their credentials, arguments, and lack of objectivity. James Lawrence Powell shows that the deniers use a wide variety of deceptive rhetorical techniques, many stretching back to ancient Greece. Carefully researched, fully referenced, and compellingly written, his book clearly reveals that the evidence of global warming is real and that an industry of denial has deceived the American public, putting them and their grandchildren at risk.
Presented here is a model for intelligent databases based on five information technologies: databases, object-oriented programming, expert systems, hypertext and text management. This self-contained treatment actually shows how to construct an intelligent database on a microcomputer by building a shell much like the shells used to construct expert systems. A realistic intelligent database example is used throughout the book to illustrate ideas being discussed.
This activities-based tutorial is designed to help first-year undergraduate students develop their 3-D spatial visualization skills. Adopting a multidisciplinary approach, it progresses systematically through physical model activities, paper and pencil activities, and computer activities.
This text tells the story of how epidemiologists - those who investigate patterns of disease in populations - go about their work and the many successes they had in ferretting out the causes of disease and the consequences of treatment.
