Welcome to the SuziAI project, a collection of repositories targeting digitization and AI methods for ancient Chinese suzipu 俗字谱 notation.

Suzipu notation (literal translation: common character notation), also called banzipu 半字谱 notation (literal translation: half character notation) is a notation which was predominantly used in Song dynasty in China (960–1279). In addition, the notation is still used in the actively performed music tradition of Xi'an Guyue 西安鼓乐。

The largest historical source of music written in suzipu notation is Baishidaoren Gequ 白石道人歌曲 by Jiang Kui 姜夔, a collection of poetry firstly published in 1202.

The goal of SuziAI is to promote the preservation and understanding of cultural heritage through digitization. This is achieved by conducting research about suzipu notation using digitization and methods of artificial intelligence (AI) in several different aspects:

1. Creating digital machine-readable representations of suzipu notation.
2. Toolboxes for creating digitally represented music written in suzipu, e.g., via annotation or notation editor software.
3. Development of AI tools involving suzipu notation or its music.

The subprojects currently associated with SuziAI are:

1. gui-tools: The digital representation of suzipu notation and the annotation tool for creating databases suitable for the development of OMR techniques.
2. KuiSCIMA: A digital machine-readable corpus of both purely symbolic and OMR-oriented representations of the 17 suzipu pieces from Baishidaoren Gequ.
3. SuziOMR: The development of deep learning algorithms for optical music recognition (OMR) of suzipu notation.
4. HumanAnnotationBaselineStudy: Due to the suzipu notation's ambiguity, it is difficult to assess an OMR model's performance. For this, a user study was performed to compare the OMR model's accuracy and time against the performance of human users.

4. SuziGEN: The style-based generation of melodies to ci 词 poetry in suzipu notation.
