QMUL-SDS @ DIACR-ITA2020: Evaluating Unsupervised Diachronic Lexical
Semantics Classification in Italian
International Workshop on Evaluation of Natural Language and Speech Tools for Italian (NLSTI), 2023

Abstract
In this paper, we present the results and main findings of our system for the DIACR-ITA 2020 Task. Our system focuses on using variations of training sets and different semantic detection methods. The task involves training, aligning and predicting a word's vector change from two diachronic Italian corpora. We demonstrate that using Temporal Word Embeddings with a Compass C-BOW model is more effective compared to different approaches including Logistic Regression and a Feed Forward Neural Network using accuracy. Our model ranked 3rd with an accuracy of 83.3\%.
