The development of the automatical system with a reasoning function which recognizes the character of the excavated written sources such as Wooden Tablets

自1961年在平城宫遗址出土第一个木碑（木碑）以来，奈良国立文化遗产研究所对木碑进行了超过20万次的研究。本项目将木碑档案与文字识别、信息技术等最新信息技术相结合，重点研究了木碑信息易数字化系统、木碑文字图像数据库、木碑阅读数据库、木碑文字自动识别系统等四个方面的内容。并建立了木碑上文字形象数据库“木碑记事”和木碑上文字阅读辅助系统“木碑店”。“Mokkan Jiten”包含1200个字符类别/ 20,000个字符模式的彩色/单色/红外/草图图像。“木馆店”由提取木碑墨迹部分的图像处理系统、破损纹样的文字识别系统、最新的历史地点/人物/产品名称数据库的语境处理系统组成，提高了木碑解码的价值。最后，我们成功地实现了一种创新的自动识别系统，该系统可以在部分缺陷/严重损坏/不完美的木片上读取字符模式。“木馆馆”和“木馆馆”是构建木碑等出土史料中心的有效组成部分，具有推动历史考古研究进步的潜力。为了公开我们的项目成果和其他木碑信息，我们在奈良国立文化遗产研究所的网站上制作了一个网页“木馆Hiroba”。此外，我们还出版了《日本kohon Kodai Mokkan JIten》，介绍了“平州球Mokkans”作为“Mokkan JIten”的纸质版本。

Since the first wooden tablets(Mokkan was excavated at Heijo palace site in 1961, over 200,000 wooden tablets have been researched in Nara National Research Institute for Cultural Properties. In this project, we linked the archive of wooden tablets with the latest information technology e.g. character recognition and information technology, made four core researches on 1) an easily-digitization system of the information of wooden tablets 2) a database of the character images on wooden tablets 3) databases to support reading wooden tablets 4) an automatic recognition system for characters written on wooden tablets, and built "Mokkan Jiten" that is a database of character images on wooden tablets and "Mokkan Shop' that is a support system to read characters on wooden tablets."Mokkan Jiten" contains color/monochrome/infrared/sketched images for 1,200 character categories / 20,000 character patterns. "Mokkan Shop" consisting of an image processing system to extract ink parts of wooden tablets, a character recognition system for damaged character patterns and a context processing system with the newest database of historical place/person/product name enhanced the value of decoding wooden tablets. Finally, we succeeded in practical realization of an innovative automanc-recognition-system to read character patterns on partially defective/too much damaged/imperfect condition wooden tablets."Mokkan Jiten" and "Mokkan Shop" that are the effective components to build the COE for wooden tablets and other Excavated Historical Documents, and they have the potential to make the progress of the research in history and archaeology.In order to open our achievements of this project and other information of wooden tablets, we made a web page "Mokkan Hiroba" in the web site of Nara National Research Institute for Cultural Properties. Also, we published "Nihon Kodai Mokkan JIten" that introduces the "Heijo-kyu Mokkans" as the paper-version of "Mokkan Jiten".
