In this research we have studied some recognition systems of continuous cursive scripts (Hiragana) by the conventional pattern recognition methods such as a k-NN rule and an artificial neural network. Also we have analyzed the characteristics of these continuous cursive scripts in historical documents to improve the character recognition performance. Moreover the one of comical and popular books published in Edo period in Japan, which was called as 'KI-BYOSHI', was examined, and then reported the frequency of scripts. The results of this research are as follows :1. The continuous cursive scripts data including each pixel information and category name were prepared.2. The character recognition system for the continuous cursive scripts was developed and the difficulty for correct recognition due to the continuous writing was discussed.3. The character recognition system based on the order of writing or writing procedure was proposed, and its performance of recognition rate was evaluated.4. The statistical analysis for the frequency of each script in the several historical documents in various periods was executed, then it was shown that the frequency of Hiragana had increased as the period became newer.

在本研究中，我们用传统的模式识别方法，如k-NN规则和人工神经网络，研究了一些连续草书(平假名)的识别系统。我们还分析了历史文献中这些连续草书的特点，以提高字符识别性能。此外，还考察了日本江户时代出版的一本名为《奇书》的漫画通俗读物，并报告了剧本出现的频率。研究结果如下：1.编制了包含每个像素信息和类别名称的连续草书数据。开发了连续草书的字符识别系统，并讨论了由于连续书写而导致的正确识别的困难。提出了基于书写顺序或书写顺序的字符识别系统，并对其识别率性能进行了评价。对不同时期的几部历史文献中每一种文字出现的频率进行了统计分析，发现平假名出现的频率随着时间的推移而增加。
