| Outline of Final Research Achievements |
In this research, I have designed and implemented information technologies for crossover searching of digital archives of historical character images. The technologies, accepting character pattern images as the search key, have been provided by a web site of Nara National Research Institute for Cultural Properties. The targets of the searching are the digital archives of the institute and Historiographical Institute, The University of Tokyo. In our evaluation experiment, 936,932 image keys have been used for the searching in about 19 months. The number is about two times as large as that of the keys of the search method using character codes as the keys. The results show that the new technologies satisfy the needs for information searching of the digital archives.
