Outline of Final Research Achievements

In order to promote the research of ancient musical notation with undeciphered codes, it is necessary to improve the research environment that the researchers can share the decipherment process such as saving it on share network. This research aims to produce the system for sharing the information about musical notation with undeciphered codes that is on the way of decipherment among researchers as users of ancient musical notation. First, on the condition of applicable notation to ancient musical notation whose character string is columnar writing with and without undeciphered symbols, we created a web application that recognizes and edits these symbols together with the notation. Next, we created a system for automatic classification of various sesame points that are relatively simple undeciphered musical codes. Furthermore, to retrieve complex symbols, we devised a method to divide a complex curve symbol into simple straight lines and curves, and a grammar to combine them.
