摘　　要：首先对DGP系统作了一个简单的介绍,在对DGP系统将要实现的功能有了一个大致的了解的基础上,然后通过对现有的分词技术的深入了解分析之后,决定将双向最大匹配法进行改进之后运用于DGP系统之中。对双向最大匹配法的改进主要是针对词典,方法就是根据词的长度将词典分成一个一个的块,每一块具有相同的词长。通过对双向最大匹配法的改进,提高了DGP系统分词效率和搜索的准确率,最后达到了优化DGP系统的目的。A brief introduction of DGP system is given first, and based on the conderstanding of the function of DGP system, an in-depth analysis of the word segmentation technique is done, and the dual-way maximum matching algorithm improved, and then this algorithm is applied to DGP system. The improvement of the dual-way maximum matching algorithm lies in the dictionary, that is according to the different length of the words, the dictionary is classified into different blocks and each word in the same block has the same length. With the improvement of the bual-way maximum matching algorithm, the efficiency of word segmentation and the accuracy of searching are raised, thus achieving the ultimate goal of DGP system optimization.
