English(EN) Invisible to humans, visible to machines: a preregistered audit of Unicode fidelity across four biomedical bibliographic APIs

生物医学API的Unicode保真度不一致,影响LLM训练数据

最近对四个主要的生物医学文献API——PubMed E-utilities、Crossref、OpenAlex和Semantic Scholar——进行的审计显示,它们处理Unicode字符的方式存在显著不一致。研究发现,PubMed AbstractText字段经常未能保留印刷标点符号,而OpenAlex系统性地丢失了特殊空白字符。虽然数学符号和希腊字母通常得以保留,但这些字符级别的保真度问题直接影响文本挖掘、文献计量学以及生物医学大型语言模型训练语料库的构建。 AI

影响 生物医学API中不一致的数据保真度可能会损害专业LLM训练数据的质量和可靠性,从而影响它们在科学文本分析中的性能。
