Information Storage and Retrieval

The way information is stored, retrieved and displayed is changing. Simple bibliographic databases are giving way to unregulated and unorganized multimedia data repositories, which can give the user great difficulty when searching for information. A methodology is needed to keep all of this information in its various forms retrievable. This is the first modern survey of the field of information storage and retrieval to discuss how to work with information in all its varying forms. It shows information professionals how to handle full-text, graphics, video and audio, and how to distribute these massive databases over networks.

The most comprehensive and up-to-date treatment of information storage and retrieval in over a decade

Information Storage and Retrieval is an invaluable reference on the burgeoning field of information retrieval systems. Robert Korfhage addresses the many challenges facing today's IR professionals who are restructuring the bibliographic record to include multimedia documents and creating effective measures for document retrieval in boundless environments like the Internet.

In order to access data on demand, retrieval tools must be powerful enough for today's gigabit data sets and distributed environments, and at the same time responsive to each user's information needs. By focusing on new techniques like the use of visual or graphical interfaces as a means of structuring information presented to the user, Korfhage leads the way for a new approach to IR. This book provides:

* A look at the shortcomings of the "state of the art" in Internet browsing and searching

* Retrieval effectiveness measures for text, image, and sound

* Comprehensive overview of Visual Information Retrieval Interfaces (VIRIs)

* Forthright talk about economic, privacy, copyright, and security issues

* Special appendixes on string matching techniques and ?le structures

* Instructive exercises at the end of each chapter
