Abstract: : In this article we present a new compression method, called WLZW, which is a word-based modification of classic LZW. The modification is similar to the approach used in the HuffWord compression algorithm. Due to special using WLZW in text databases, some its features seem to be preferable in comparing to similar previous approaches. The algorithm is two-phase, it uses only one table for words and non-words, and a single data structure for lexicon is usable as text index. The compression ratio ... (Update)
