Ian Witten, Alistair Moffat, and Timothy Bell have updated their original work with this even more impressive second edition. This version adds recent techniques such as block-sorting, new indexing techniques, new lossless compression strategies, and many other elements to the mix. In short, this work is a comprehensive summary of text and image compression, indexing, and querying techniques. The history of relevant algorithm development is woven well with a practical discussion of challenges, pitfalls, and specific solutions.
This title is a textbook-style exposition on the topic, with its information organized very clearly into topics such as compression, indexing, and so forth. In addition to diagrams and example text transformations, the authors use "pseudo-code" to present algorithms in a language-independent manner wherever possible. They also supplement the reading with mg--their own implementation of the techniques. The mg C language source code is freely available on the Web.
Alone, this book is an impressive collection of information. Nevertheless, the authors list numerous titles for further reading in selected topics. Whether you're in the midst of application development and need solutions fast or are merely curious about how top-notch information management is done, this hardcover is an excellent investment. --Stephen W. Plain
Topics covered: Text compression models, including Huffman, LZW, and their variants; trends in information management; index creation and compression; image compression; performance issues; and overall system implementation.
It has been 8 years since it was published and I could see it is still one of the best in IR field. Without much long magic equations, it is not hard for common user to pick it up. Read morePublished on April 19, 2007 by Zhefu Zhang

This is one of those rare books that succeeds both on a theoretical and practical level. The theory underlying management and retrieval of large collections of mixed text and image... Read morePublished on September 17, 1999
I found MG exceedingly readable, and particularly useful. The ideas are very well explained, and the problems are solved in a stepwise fashion, leading from a simple, inefficient... Read morePublished on August 27, 1999 by firstname.lastname@example.org
