Worked on enhancing linguistic documentation for the UniversalDependencies/docs repository, focusing on Occitan language relations. Improved the clarity and accuracy of acl:relcl and aux:pass documentation by providing precise definitions and usage examples sourced from UD_Occitan-CorAG. Removed outdated notes, such as advcl:cleft, to reduce confusion and align documentation with current Universal Dependencies data. Emphasized traceability and reproducibility by maintaining detailed commit records. Utilized Markdown for documentation and applied skills in linguistics and natural language processing to ensure the updates would support both contributors and downstream tooling. The work addressed documentation gaps and improved guidance for future development efforts.
