This book was released on 2007-08-20 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intelligent information Retrieval comprehensively surveys scientific information retrieval, which is characterized by growing convergence of information expressed in varying complementary forms of data - textual, numerical, image, and graphics; by the fundamental transformation which the scientific library is currently being subjected to; and by computer networking which as become an essential element of the research fabric. Intelligent Information Retrieval addresses enabling technologies, so-called `wide area network resource discovery tools', and the state of the art in astronomy and other sciences. This work is essential reading for astronomers, scientists in related disciplines, and all those involved in information storage and retrieval.

Available in PDF, EPUB and Kindle. Book excerpt: Although a large number of natural language database interfaceshave been developed, there have been few empirical studies of theirpractical usefulness. This paper presents the design and results of afield evaluation of a natural language system - NLS - used for dataretrieval .A balanced, multifactorial design comparing NLS with a referenceretrieval language, SQL, is described. The data are analyzed on twolevels: work task (n=87) and query (n=1081). SQL performed betterthan NLS on a variety of measures, but NLS required less effort touse. Subjects performed much poorer than expected based on theresults of laboratory studies. This finding is attributed to thecomplexity of the field setting and to optimism in grading laboratoryexperiments.The methodology developed for studying computer languages in realwork settings was successful in consistently measuring differences intreatments over a variety of conditions.

Available in PDF, EPUB and Kindle. Book excerpt: An information retrieval (IR) system is designed to analyse, process and store sources of information and retrieve those that match a particular user's requirements. A bewildering range of techniques is now available to the information professional attempting to successfully retrieve information. It is recognized that today's information professionals need to concentrate their efforts on learning the techniques of computerized IR. However, it is this book's contention that it also benefits them to learn the theory, techniques and tools that constitute the traditional approaches to the organization and processing of information. In fact much of this knowledge may still be applicable in the storage and retrieval of electronic information in digital library environments. The fully revised third edition of this highly regarded textbook has been thoroughly updated to incorporate major changes in this rapidly expanding field since the second edition in 2004, and a complete new chapter on citation indexing has been added. Unique in its scope, the book covers the whole spectrum of information storage and retrieval, including: users of IR and IR options; database technology; bibliographic formats; cataloguing and metadata; subject analysis and representation; automatic indexing and file organization; vocabulary control; abstracts and indexing; searching and retrieval; user-centred models of IR and user interfaces; evaluation of IR systems and evaluation experiments; online and CD-ROM IR; multimedia IR; hypertext and mark-up languages; web IR; intelligent IR; natural language processing and its applications in IR; citation analysis and IR; IR in digital libraries; and trends in IR research. Illustrated with many examples and comprehensively referenced for an international audience, this is an indispensable textbook for students of library and information studies. It is also an invaluable aid for information practitioners wishing to brush up on their skills and keep up to date with the latest techniques.
