Tree Structure Compression with RePair
Larsson and Moffat’s RePair algorithm is generalized from strings to trees. The new algorithm (TreeRePair) produces straight-line linear context-free tree (SLT) grammars which a...

The Context Trees of Block Sorting Compression
Abstract. The Burrows-Wheeler transform (BWT) and block sorting compression are closely related to the context trees of PPM. The usual approach of treating BWT as merely a permutat...

Dynamic Markov Compression Using a Crossbar-Like Tree Initial Structure for Chinese Texts
This paper proposes the use of a crossbar-like tree structure to use with Dynamic Markov Compression (DMC) for the compression of Chinese text files. DMC had previously been found...

Efficient memory representation of XML document trees
Implementations that load XML documents and give access to them via, e.g., the DOM, suffer from huge memory demands: the space needed to load an XML document is usually many times...
