Abstract
Some text compression methods take advantage from using more complex compression units than characters. The synchronization between coder and decoder then can be done by transferring the unit dictionary together with the compressed message.
We propose to use a dictionary compression method based on a proper ordering of nodes of the tree-organized dictionary. This reordering allows achieving of better compression ratio.
The proposed dictionary compression method has been tested to compress dictionaries for word- and syllable-based compression methods. It seems to be effective for compressing dictionaries of syllables, and promising for larger dictionaries of words.
