In April 2025, Adam McDonald enhanced the UniversalDependencies/docs repository by developing comprehensive documentation for Old Irish tokenization and word segmentation. He focused on clarifying the distinctions between diplomatic and critical editions, addressing common ambiguities faced by researchers and improving annotation consistency. Using Markdown, Adam updated the index to include recent academic resources, thereby increasing the discoverability and reproducibility of Old Irish treebank research. His work leveraged skills in documentation, linguistics, and natural language processing to deliver clear, traceable guidance that supports both new and experienced annotators. The depth of the updates reflects a thoughtful approach to scholarly documentation standards.
