Managing gigabytes

Compressing and indexing documents and images

Ian H. Witten, Alistair Moffat, Timothy C. Bell

600 pages, parution le 01/05/1999

Résumé

This volume describes state-of-the-art techniques for efficiently compressing, storing, and retrieving large documents comprising gigabytes of data. The challenges in managing such huge volumes of data are twofold: storing this data efficiently and providing fast access through keyword searches. For this, a tailor-made electronic index must be constructed, and traditional methodsd of compression and searching need to be adapted. These two topics are the focus of this book, and the end result of applying the techniques explained here is a computer system that can store millions of documents and retrieve the documents that contain any given combination of keywords in a matter of seconds or less.
