| Outline of Final Research Achievements |
The purpose of this research is to realize reprint of handwritten Japanese historical Kana text by combining pattern recognition and constraint solving, which was not achieved by the conventional methods. The system which our research aims selects appropriate character recognition results as a whole from combination of plural character recognition results of each character using a constraint solver. We implemented the constraint solver as a Web service and a system with a graphical user interface (GUI) which invokes the constraint solver. The system makes it possible to generate a constraint satisfaction problem (CSP) from character segmentation results, character reading order, and plural recognition results of each character specified via the GUI and to show solutions to the CSP visually.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は古文書の翻刻作業を支援する技術に関するものである。古文書には現行仮名だけでなくその異体字である変体仮名も使われている。さらにそれらが崩された形で書かれている。そのため現代の日本人が古文書を読むことが困難になっている。本研究の特徴は、全体として自然な文となるように一文字ずつの文字認識結果を補正する点にある。このような技術によって古文書の内容がコンピュータで活用しやすくなる。
