This book is intended for those in the library community with an
understanding of library processes and a desire to actually make
use of scientific management techniques. The emphasis is on
presenting insights into which tool may be appropriate for
particular problems, not on the isolated understanding of
theoretical issues. It does not require an extensive mathematical
background. It shows well-developed examples of solving library
problems and features chapter summaries and questions for further
study.
This will be the third edition of the highly successful ???Text
Information Retrieval Systems???. The book's purpose is to teach
people who will be searching or designing text retrieval systems
how the systems work. For designers, it covers problems they will
face and reviews currently available solutions to provide a basis
for more advanced study. For the searcher its purpose is to
describe why such systems work as they do. The book is primarily
about computer-based retrieval systems, but the principles apply to
nonmechanized ones as well. The book covers the nature of
information, how it is organized for use by a computer, how search
functions are carried out, and some of the theory underlying these
functions. As well, it discusses the interaction between user and
system and how retrieved items, users, and complete systems are
evaluated. A limited knowledge of mathematics and of computing is
assumed.
This third edition will be updated to include coverage of the WWW
and current search engines. In many cases, examples of non-web
searching will be replaced with web-based illustrations. Coverage
of interfaces, various features available to assist searchers, and
areas in which search assistance is not available will also be
covered. In addition, the book will have a web dimension which will
include relevant material available online, to be used in
conjunction with the text.
*Follow-up to the award winning 2nd Edition
*Focuses on computer-based sytem but basic principles can be
applied to any information seeking context
