In February 2025, S. Beranek refactored the SpellingConversionJob in the rwth-i6/i6_core repository to support multi-mapping for lexicon conversions, addressing the need for more flexible and accurate data processing. Using Python, Beranek implemented logic to handle multiple mappings per lexicon entry, removed duplicate orthographic forms, and ensured syntactic information was correctly linked to lemmas. This work improved the consistency and reliability of lexicon management, particularly for downstream parsing and analysis tasks. The changes focused on data clean-up and structural improvements, demonstrating a solid understanding of both data processing and the complexities of lexicon management workflows.
