Abstract
There are many ways of text compression, but they are all grouped by two large yl oups: lossless and lossy compression, and from that alone, the lossless method can '111 be divided imo two types: Statistical Compression and Dictionary-based compression. This project will examine the effectiveness of these two methods, which .me IS more effective for compressing lext files. Shannon - Fano Algorithm is used to '''present Statistical Compre ssion and Lempel-Ziv 1977(LZ77) algorithm is used to I'!present dictionary-based compression. The final result is, the program is able to compress using the two Iforemencioned algorithms and generate the output file. But the file generation cannot ;Jork In rhe graphical mode, only in fexr mode. And rhe LZ77-compressed file always 'las smaller file size than the Shannon-Fano-compressed one. iv ABSTRACT There
