A Systematic Comparison of Contextualized Word Embeddings for Lexical Semantic Change

1 code implementation19 Feb 2024 Francesco Periti, Nina Tahmasebi

Our evaluation is performed across different languages on eight available benchmarks for LSC, and shows that (i) APD outperforms other approaches for GCD; (ii) XL-LEXEME outperforms other contextualized models for WiC, WSI, and GCD, while being comparable to GPT-4; (iii) there is a clear need for improving the modeling of word meanings, as well as focus on how, when, and why these meanings change, rather than solely focusing on the extent of semantic change.

Challenges for Computational Lexical Semantic Change

no code implementations19 Jan 2021 Simon Hengchen, Nina Tahmasebi, Dominik Schlechtweg, Haim Dubossarsky

The computational study of lexical semantic change (LSC) has taken off in the past few years and we are seeing increasing interest in the field, from both computational sciences and linguistics.

SemEval-2020 Task 1: Unsupervised Lexical Semantic Change Detection

2 code implementations SEMEVAL 2020 Dominik Schlechtweg, Barbara McGillivray, Simon Hengchen, Haim Dubossarsky, Nina Tahmasebi

Lexical Semantic Change detection, i. e., the task of identifying words that change meaning over time, is a very active research area, with applications in NLP, lexicography, and linguistics.

Parameter Transfer across Domains for Word Sense Disambiguation

no code implementations RANLP 2017 Sallam Abualhaija, Nina Tahmasebi, Diane Forin, Karl-Heinz Zimmermann

Word sense disambiguation is defined as finding the corresponding sense for a target word in a given context, which comprises a major step in text applications.
