In December 2024, Chris Manning updated the dataset splitting guidelines for the UniversalDependencies/docs repository, focusing on improving documentation quality and clarity. He refined recommendations for training, development, and test split sizes by analyzing total word count, and documented detailed data distribution rules for running text, domains and genres, overlapping treebanks, and multilingual parallel treebanks. Using Markdown and leveraging his technical writing and documentation skills, Chris ensured the guidelines addressed practical data management scenarios. He also identified and flagged a dead link for future remediation. The work demonstrated thorough attention to detail and addressed nuanced requirements for dataset preparation and documentation.
