The book "Syllable-based Compression" by Jan Lánský offers a comprehensive analysis and innovative approaches to text compression, focusing on syllables as the alphabet. In today's digital world, where efficient data storage and transmission are crucial, this work serves as a valuable resource. It highlights the advantages of syllable-based compression, particularly for languages with rich morphology and for smaller files. The methods presented are not limited to syllables but can also be applied to words. The book discusses various compression techniques, including LZW and Huffman coding, and describes their optimization through the use of an initialized dictionary. Additionally, the XBW project is introduced, which enables a combination of several advanced compression methods to efficiently handle very large files. The research also includes the compression of non-well-formed XML files, thus providing a wide range of applications for professionals and researchers in the field of data compression.
