Evaluating Shortest Edit Script Methods for Contextual Lemmatization (2024.lrec-main)
Copied to clipboard
| Challenge: | Modern contextual lemmatizers often rely on automatically induced Shortest Edit Scripts (SES) supervised contextual methods are used to perform lemma classification tasks. |
| Approach: | They propose to use masked language encoders to compute shortest edit Scripts (SES) SES is the number of edit operations to transform a word form into its lemma . |
| Outcome: | The proposed model outperforms language-specific models in all evaluation settings with seven languages of different morphological complexity. |
Lemma Dilemma: On Lemma Generation Without Domain- or Language-Specific Training Data (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large language models (LLMs) can generate lemmas in context without prior fine-tuning. |
| Approach: | They compare in-context lemma generation with traditional fully supervised approaches . they use encoder-only supervised methods and cross-lingual methods . |
| Outcome: | The proposed model outperforms the traditional fully supervised approach in the context of lemmatization tasks. |
