| 摘 要： | 现有的基于字典的压缩方法,其字典无论是静态字典还是动态生成,均处在本地。本文提出基于网络字典的无损数据压缩方法,是将各种类型的字典保存在专用服务器中,通过全文直接压缩或者分块压缩的方式进行压缩,其理想压缩效率接近100%,与现有压缩算法相比,其压缩时间主要取决于网络速度和匹配算法,随着网络速度的不断提高和匹配算法的不断改进,该方法必将带来压缩史上的一次革命性变化。

| Abstract: | The present compression schemes based on static and dynamic dictionaries can only be stored locally.This paper proposes that the lossless compression schemes based on online dictionaries can store different dictionaries in the special server.The dictionaries can be compressed in full or in section,whose effectiveness can reach almost 100%.Because such losses compression schemes depend mainly on net speed and match algorithm in contrast to the present compression algorithm,the schemes must lead to a revolution in compression field given the development of net speed and match algorithm. |
