Developed and delivered the SAOLhist Plus (v1.0) lexicon resource for the spraakbanken/metadata repository, providing comprehensive historical and modern Swedish vocabulary data spanning 1874 to 2015. Focused on lexicon curation and metadata management, the work involved creating lemmatized forms and detailed analyses, as well as refining metadata fields such as date ranges, resource statistics, and contributor information. Utilized YAML for precise file formatting and ensured the resource integrated smoothly with downstream NLP workflows. Enhanced repository documentation and governance artifacts to support reproducibility and discoverability, resulting in a well-structured, metadata-rich resource for linguistic and computational research applications.
