本文提出了一种算法，检查旋律相似性和音乐摘要系统称为“Papipuun。”首先，我们开发了一个数据结构，用于表示基于时间跨度减少生成理论的音调音乐（GTTM）和演绎面向对象的数据库（DOOD）的复调。一个最小的上限操作被引入到我们的方法中所表示的多音素的相似性检查。接下来，Papipuun以类似于在划痕记录上的手写笔跳过的方式执行快速收听，但是跳过正确地发生在音乐短语的标点处，而不是任意地。Papipuun可以通过符号化的方式产生高质量的音乐摘要，通过与用户的互动反映整个作品的氛围。在Papipuun的预处理阶段，用户使用称为TS编辑器的专用工具通过时间跨度缩减来分析输入片段。对于实时阶段，用户与主系统Summarizer交互以执行音乐摘要。摘要器通过相似性检查来确定文章结构。当用户确定要跳过的片段时，Summarizer会删除它们并连接其余的片段。
This paper presents an algorithm that checks for melodic similarity and a music summarization system called “Papipuun.” First, we developed a data structure for representing polyphony based on a time-span reduction in the generative theory of tonal music (GTTM) and the deductive object-oriented database (DOOD). A least upper bound operation is introduced to check the similarity of polyphonies represented in our method. Next, Papipuun performs quick listening in a manner similar to stylus skipping on a scratched record, but the skipping occurs correctly at punctuations of musical phrases, not arbitrarily. Papipuun can produce a music summary of good quality with a symbolic approach, reflecting the atmosphere of an entire piece through interaction with the user. In a pre-processing phase of Papipuun, a user analyzes an input piece by time-span reduction, using a dedicated tool called TS-Editor. For the real-time phase, the user interacts with the main system, Summarizer, to perform music summarization. The summarizer ascertains a piece structure by similarity checking. When the user identifies fragments to be skipped, Summarizer deletes them and concatenates the rest.
