Abstract

We present the results of our participation in the DIACR-Ita shared task on\nlexical semantic change detection for Italian. We exploit Average Pairwise\nDistance of token-based BERT embeddings between time points and rank 5 (of 8)\nin the official ranking with an accuracy of .72. While we tune parameters on\nthe English data set of SemEval-2020 Task 1 and reach high performance, this\ndoes not translate to the Italian DIACR-Ita data set. Our results show that we\ndo not manage to find robust ways to exploit BERT embeddings in lexical\nsemantic change detection.\n
