Canterbury Corpus
Encyclopedia
The Canterbury Corpus is a collection of files
intended for use as a benchmark for testing lossless data compression
algorithms. It was created in 1997 at the University of Canterbury
, New Zealand
and designed to replace the Calgary Corpus

Computer file
A computer file is a block of arbitrary information, or resource for storing information, which is available to a computer program and is usually based on some kind of durable storage. A file is durable in the sense that it remains available for programs to use after the current program has finished...

Lossless data compression
Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be reconstructed, in exchange...

Calgary Corpus
The Calgary Corpus is a collection of text and binary data files, commonly used for comparing data compression algorithms. It was created by Ian Witten, Tim Bell and John Cleary from the University of Calgary in 1987 and was commonly used in the 1990s...
