OP-IMS @ DIACR-Ita: Back to the Roots: SGNS+OP+CD still rocks Semantic Change Detection
This demonstrates that established methods remain highly effective for semantic change detection in Italian, though it is an incremental application to a specific domain.
The authors tackled lexical semantic change detection for Italian using a traditional type-based approach combining Skip-Gram with Negative Sampling, Orthogonal Procrustes alignment, and Cosine Distance, achieving near-perfect accuracy of 0.94 and winning the DIACR-Ita shared task.
We present the results of our participation in the DIACR-Ita shared task on lexical semantic change detection for Italian. We exploit one of the earliest and most influential semantic change detection models based on Skip-Gram with Negative Sampling, Orthogonal Procrustes alignment and Cosine Distance and obtain the winning submission of the shared task with near to perfect accuracy .94. Our results once more indicate that, within the present task setup in lexical semantic change detection, the traditional type-based approaches yield excellent performance.
