摘要：本文针对几种常用的文本压缩算法进行总结,并对压缩率进行了一个比较且对这几种算法的优缺点进行了分析.由此针对中文文本的压缩算法提出改进,设计并实现了一种改进的LZSS压缩算法.通过测试,可以确认,提出的改进算法是有效的：相对于标准LZSS压缩算法,压缩效率有了很大幅度的提高,对于中文文本长文件,其最大压缩比已经达到20左右；对于英文文本文件的压缩效果也好LZSS算法.关键词：数据压缩； 文本压缩；压缩率；LZSS；字典

Answer 1

Summary:This text aim at a few in common use text origin compress calculate way to carry on summary,and to compress the rate carried on a comparison and to this the merit and shortcoming of a few calculate way carried on analysis.Aim at Chinese text from here origin of compress calculate way to put forward an improvement,design and realization a kind of improvement of LZSS compress calculate way.Pass a test,can confirm,put forward of improvement calculate way is valid:Opposite in standard LZSS compress calculate way,compress the efficiency had very significant of exaltation,for Chinese text origin long document,it being the biggest compress is orer so than having already attain 20;To the compress of English text file's effect all right LZSS calculate way.Keyword:The data compress; Text origin compress;Compress a rate;LZSS;Dictionary
