Dados das cartas FC04 - C1 a C6 - ALiB

This dataset contains derived and structured linguistic data used in the article “RHOTICS AND THE DIALECTAL CONFIGURATION OF BRAZILIAN PORTUGUESE: FROM NASCENTES TO THE ALIB ”, obtained from the analytical extraction of maps F04 C1–C6 of the Atlas Linguístico do Brasil (ALiB). The data describe the distribution of rhotic segments in syllable coda position, organized by map, grammatical class, phonological context, Brazilian administrative region, and capital city. The dataset distinguishes between maps that indicate only presence or absence of the rhotic segment and those that specify its phonetic realizations. All data are aggregated and non-identifiable. No raw interview data or individual speaker information are included. The dataset enables the reproducibility of the analytical procedures described in the article without re-digitizing cartographic images.本数据集包含用于论文《巴西葡萄牙语的卷舌音与方言配置：从纳斯森特斯到ALiB》的衍生结构化语言数据，该数据源自对巴西语言地图集（Atlas Linguístico do Brasil，ALiB）中F04 C1–C6系列地图的分析提取。数据按地图、语法类别、音系语境、巴西行政区域及首府进行组织，描述了音节尾位置的卷舌音段（rhotic segments）的分布情况。 本数据集区分了两类地图：一类仅标注卷舌音段的存在与否，另一类则明确标注其语音实现形式。所有数据均经过聚合处理，无法识别个体信息，未包含原始访谈数据或单个说话者的相关资料。本数据集可复现论文中所述的分析流程，无需重新对制图图像进行数字化操作。
