Quote: XRAY compression for large text/nontext files, random access, and new data; efficient; training phase, testing phase to adjust the phrase model, and coding phase

Quotation Skeleton

We propose a new compression scheme [XRAY] that can compress large files, permits random access to compressed … nontext collections. Our scheme is a phrase-based technique … [with] origins in the Ziv-Lempel family … [p. 331] The XRAY scheme has several phases: first … dictionary; second, a testing phrase where the model … coding phase, where the complete collection is compressed … With these heuristics, we have used XRAY to … [ref] … only GZIP is typically faster in decompression than … we show that [XRAY] achieves better compression than … [ref] … and marginally worse compression than BZIP2   Google-1   Google-2
