Textual Information Retrieval: Latest State of the Art Techniques Used for Printed & Artificial Multimedia Text Retrieval.

This book describes straightforward techniques for printed & multimedia textual information retrieval that have been solidly established through extensive testing and are easy to apply. They are useful for many different types of text material, are viable for very large files, and gave the advantage that they do not require special skills or training for searching, but are easy for end users. The text retrieval methods described in this book have a sound theoretical basis, are well established by extensive testing, and the ideas involved are now implemented in some physically working systems. Testing done for the performance evaluation of techniques has, in particular, shown that the methods presented in the book work very well with full texts, not only title and abstracts, and with large files of texts containing more then three quarters of a million documents.
