Definition generation for lexical semantic change detection (2024.findings-acl)
Copied to clipboard
| Challenge: | a number of studies have attempted to bridge the gap between lexical semantic change detection and sense-based LSCD methods. |
| Approach: | They propose a sense distribution based LSCD method which uses contextualized word definitions as 'senses' they argue that the method preserves interpretability and allows to inspect the reasons behind a specific shift in terms of discrete definitions-as-sense. |
| Outcome: | The proposed method outperforms previous sense-based methods on five datasets and three languages and preserves interpretability and allows to inspect the reasons behind a specific shift in terms of discrete definitions-as-senses. |
Enriching Word Usage Graphs with Cluster Definitions (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing word usage graphs lack human interpretability of senses. |
| Approach: | They propose to enrich existing word usage graphs with cluster labels functioning as sense definitions. |
| Outcome: | The proposed dataset matches the definitions chosen from WordNet by two baseline systems. |
Explaining novel senses using definition generation with open language models (2025.findings-emnlp)
Copied to clipboard
| Challenge: | We apply definition generators based on open-weights large language models to create explanations of novel senses. |
| Approach: | They apply open-weights large language models to create explanations of novel senses using target word usages as input. |
| Outcome: | The proposed definition generators perform on par with decoder-only models. |
