Semantic Lossy Compression of XML Data - Cannataro, Carelli, Pugliese, Sacca   (4 citations)  (Correct)

.... Lossy compression allows to obtain significantly higher compression ratios preserving a representative subset of original data; interesting approaches to lossy compression are wavelet transformations [11] histograms [9, 12] and methods for the extraction of significant parts from a free text [13]. XML uses markups to identify and describe data; the schema related information is contained in documents themselves so the language is called self describing. Therefore, it is always possible to directly identify data through their paths; this feature becomes specially useful when when data ....
