Introduction to Modern Information Retrieval

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. This book covers topics in information storage and retrieval, including: users of IR and IR options; database technology; bibliographic formats; and abstracts and indexing. 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.

It is recognized that today's information professionals need to concentrate their efforts on learning the techniques of computerized information retrieval. However, it is this book's contention that it also benefits them to learn in depth the theory, techniques and tools that constitute the traditional approaches to the organization and processing of information.The text is one of the first to blend together the traditional and the new, and to give the student of information studies a comprehensive view of information retrieval. Unique in its scope, it covers the whole spectrum of information storage and retrieval.Illustrated with many examples and comprehensively referenced for an international audience, this is a textbook for students of library and information studies undertaking courses in information retrieval, information organization, information use and knowledge-based systems at both undergraduate and postgraduate level.
