摘　　要：传统的XML压缩算法对XMPP通信中产生的XML数据压缩虽然能达到很高的压缩率,但是还有改进的余地,文中利用XMPP通信中产生的XML数据特点、社区矫正通信应用场景时产生和使用的数据具有相似性的特点对已有算法进行了优化;另外,还对传统压缩算法大多是针对英文,未考虑中文的特点做了相应的改善,使其更好地压缩中文信息。结果表明,改进后的压缩算法相比传统压缩算法,在社区矫正通信系统中压缩率更高。The traditional XML compression algorithm can achieve a high compress ratio on the XML data generated in XMPP communication,but there is room for the improvement. In this paper,the traditional compression algorithm is optimized by using the characteristics of XML data generated in XMPP communication and the similarity of data generated and used in community correction communication application scene. In addition to the traditional compression algorithm is mostly for English,it did not consider the characteristics Chinese, the paper proposes a method to do a corresponding improvement to make it better to compress Chinese information. The results show that the improved compression algorithm is better than the traditional compression algorithm in community correction communication system.
