Rhyme, Syllabic, and Repetition Dataset of English Nursery Rhymes (RSR)

The Rhyme, Syllabic, and Repetition Dataset of English Nursery Rhymes (RSR) provides document-level structural measurements for 308 English nursery rhymes. Each nursery rhyme is represented by twelve structural features covering three linguistic dimensions: rhyme, syllabic structure, and repetition. Rhyme is represented by Rhyme Participation Rate, Rhyme Density, Number of Rhyme Classes, Perfect Rhyme Lines, Perfect Rhyme Pairs, and Rhyme Scheme. Syllabic structure is represented by Mean Syllable Count, SD Syllable Count, and Syllabic CV. Repetition is represented by Word Repetition Rate, Phrase Repetition Rate, and Line Repetition Rate. The repository also includes line-level processing records, pronunciation and out-of-vocabulary audits, syllable-estimation records, repetition audits, consistency checks, and supporting files for dataset validation and computational reproducibility. The dataset is intended to support structural analysis of English nursery rhymes and may be used for comparative analysis, clustering, classification, and other computational linguistics or natural language processing applications.英语童谣韵脚、音节与重复数据集（Rhyme, Syllabic, and Repetition Dataset of English Nursery Rhymes，缩写RSR）为308首英语童谣提供文档级结构量化表征。每首英语童谣均通过覆盖三大语言维度的12项结构特征进行表征，三大维度分别为韵脚、音节结构与重复模式。韵脚维度涵盖韵脚参与率、韵脚密度、韵脚类别数、完全韵脚行数、完全韵脚对与韵式共六项特征；音节结构维度涵盖平均音节数、音节数标准差及音节CV结构三项特征；重复模式维度涵盖词汇重复率、短语重复率与行级重复率三项特征。该数据集仓库还包含行级处理记录、发音与未登录词（out-of-vocabulary）审核记录、音节估算记录、重复模式审核记录、一致性校验文件，以及用于数据集验证与计算可复现性的配套辅助文件。本数据集旨在支撑英语童谣的结构分析工作，亦可应用于对比分析、聚类、分类等计算语言学或自然语言处理相关任务。
