A Quasi Word-Based Compression Method of English Text Using Byte-Oriented Coding Scheme

Abstract

In this paper we present a universal compression algorithm for English text, ERecode. The proposed scheme highlights the importance of pre-processing work for English text, and employs one or two bytes code values to recode the 511 most common used English words, sequences of symbols and ASCII codes based on their occurrence frequency. Acting as a pre-processing tool for English text by the popular compression utilities, ERecode can improve their compression ratio from 0.89% to 19.65%. The proposed method also is applicable to text files for other languages.
