The Indo-European Cognate Relationships (IE-CoR) dataset is an open-access relational dataset showing how related, inherited words ('cognates') pattern across 160 languages of the Indo-European family. IE-CoR is intended as a benchmark dataset for computational research into the evolution of the Indo-European languages. It is structured around 170 reference meanings in core lexicon, and contains 25731 lexeme entries, analysed into 4981 cognate sets. Novel, dedicated structures are used to code all known cases of horizontal transfer. All 13 main documented clades of Indo-European, and their main subclades, are well represented. Time calibration data for each language are also included, as are relevant geographical and social metadata. Data collection was performed by an expert consortium of 89 linguists drawing on 355 cited sources. The dataset is extendable to further languages and meanings and follows the Cross-Linguistic Data Format (CLDF) protocols for linguistic data. It is designed to be interoperable with other cross-linguistic datasets and catalogues, and provides a reference framework for similar initiatives for other language families.
印欧语系同源关系（IE-CoR）数据集是一个开放获取的关系型数据集，展示了印欧语系160种语言中相关的、继承而来的词汇（“同源词”）的分布模式。IE-CoR旨在作为印欧语系语言演化计算研究的基准数据集。它围绕核心词汇中的170个参考意义构建，包含25731个词位条目，被分析为4981个同源词集。使用新颖的专用结构对所有已知的水平转移情况进行编码。印欧语系所有13个主要的有文献记载的分支及其主要子分支都有很好的体现。还包括每种语言的时间校准数据以及相关的地理和社会元数据。数据收集由一个由89位语言学家组成的专家团队进行，参考了355个引用来源。该数据集可扩展到更多语言和意义，并遵循语言数据的跨语言数据格式（CLDF）协议。它旨在与其他跨语言数据集和目录实现互操作，并为其他语系的类似项目提供参考框架。
