SANDWiCH: Semantical Analysis of Neighbours for Disambiguating Words in Context ad Hoc (2025.naacl-long)
Copied to clipboard
| Challenge: | Recent studies show that language understanding offered by chat-based Large Language Models is limited and far from human-like performance. |
| Approach: | They propose a framework for multilingual Word Sense Disambiguation using group algebra. |
| Outcome: | The proposed framework surpasses the performance of current alternatives even in low-resource languages while reducing the parameter count by 72%. |
Back to the Basics: A Quantitative Analysis of Statistical and Graph-Based Term Weighting Schemes for Keyword Extraction (2021.emnlp-main)
Copied to clipboard
| Challenge: | Term weighting schemes are widely used in Natural Language Processing and Information Retrieval. |
| Approach: | They perform an exhaustive and large-scale empirical comparison of term weighting methods in the context of keyword extraction using tf-idf. |
| Outcome: | The proposed methods have advantages over tf-idf, and qualitative differences between them. |
