In this paper, we propose a method of text retrieval from document images using a similarity measure based on an N-Gram algorithm.

该程序基于Bi-Gram模型算法思想对一训练文本中的词汇建立语言模型，而后对测试文本中的语句进行预测出现概率-The program is based on Bi-Gram model algorithm ideas on a training text vocabulary build language model, and then the text of the statement of the test to predict the probability of occurrence
