Describes a method of text compression that works by replacing a substring with a pointer to an earlier occurrence of the same substring. Although it performs quite well, it does not provide a clear separation between modeling and coding.

    About the authors...

    Tim Bell reseived a B.Sc. (First Class Honours) and Ph.D. from the University of Canterbury, New Zealand. In 1987 he held a post-doctoral fellowship at the Knowledge Sciences Institute, University of Calgary, Canada. He currently teaches at the University of Canterbury. His interests include text compression, algorithms, and the use of computers for music performance, composition, and printing.

    Ian H. Witten is Professor of Computer Science at the University of Calgary, Canada. In the past he has worked on numerous aspects of man-machine systems, particularly speech synthesis and documentation graphics. His current research interests include prediction and modeling, machine learning, and office information systems. He has published around 80 papers and three books: Communication with Microcomputers (Academic Press,1980), Principles of Computer Speech (Academic Press,1982), and Talking with Computer (Prentice Hall,1986).

    John G.Cleary is Associate Professor of Computer Science at the University of Calgary, Canada. He received his Ph.D. in electrical engineering from the University of Canterbury, New Zealand.
