Produktbeschreibung

Text and Context: Document Storage and Processing describes information processing techniques, including those which do not appear in conventional textbooks on database systems. It focuses on the input, storage, retrieval and presentation of primarily textual information, together with auxiliary material about graphic and video data. There are chapters on text analysis as a basis for lexicography, full-text databases and information retrieval, the use of optical storage for both ASCII text and scanned document images, hypertext and multi-media systems, abstract document definition, and document formatting and imaging. The material is treated in an informal way with an emphasis on real applications and software. There are, among others, case studies from Reuters, British Airways, St. Bartholomew's Hospital, Sony, and HMSO. Relevant industry standards are discussed including ISO 9660 for CD-ROM file storage, CCITT Group4 data compression, the Standard Generalised Markup Language and Office Document Architecture, and the Postscript language. Readers will benefit from the way Susan Jones has brought together this information, in a logical sequence, to highlight the connections between related topics. This book will be of interest to second and third year undergraduates and MSc students in computer science, to B/TEC HTD final year computing and information science students either specialising in IT or taking an IT option, and to students taking courses in IT and in business computing systems.
