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.
