首个萨丁尼亚即兴诗歌语料库，助力小语种语言保护与计算分析。
A Bolu: A Structured Dataset for the Computational Analysis of Sardinian Improvisational Poetry
- 构建首个萨丁尼亚方言即兴诗歌结构化语料库
- 包含2835节诗共141,321个词元，揭示重复模式规律
- 支持口头创作理论，推动小语种NLP工具发展
自然语言处理对少数语言的兴趣日益增长，但尚未弥补口头语言遗产保护的差距。特别是基于实时即兴创作、韵律修辞能力的即兴诗歌，仍是计算语言学中未被充分探索的领域。为此，研究者创建了首个针对萨丁尼亚语卡塔达·卢古多雷塞方言的即兴诗歌结构化语料库——A Bolu。该语料库包含2,835节诗，总计141,321个词元。研究通过描述性统计指标与计算语言学技术相结合，对诗歌文本特征进行多维度分析。结果表明，萨丁尼亚即兴诗人创作具有反复出现的模式，支持帕里与洛德的公式化理论。这一发现不仅为理解口头创造力提供了新视角，也对开发更包容、敏感于非主流语言特性的NLP工具具有重要意义。
原文摘要 · Abstract (English)
The growing interest of Natural Language Processing (NLP) in minority languages has not yet bridged the gap in the preservation of oral linguistic heritage. In particular, extemporaneous poetry - a performative genre based on real-time improvisation, metrical-rhetorical competence - remains a largely unexplored area of computational linguistics. This methodological gap necessitates the creation of specific resources to document and analyse the structures of improvised poetry. This is the context in which A Bolu was created, the first structured corpus of extemporaneous poetry dedicated to cantada logudorese, a variant of the Sardinian language. The dataset comprises 2,835 stanzas for a total of 141,321 tokens. The study presents the architecture of the corpus and applies a multidimensional analysis combining descriptive statistical indices and computational linguistics techniques to map the characteristics of the poetic text. The results indicate that the production of Sardinian extemporaneous poets is characterised by recurring patterns that support Parry and Lord's theory of formulaicity. This evidence not only provides a new key to understanding oral creativity, but also offers a significant contribution to the development of NLP tools that are more inclusive and sensitive to the specificities of less widely spoken languages.
