Abstract

This paper presents a multilingual approach to hope speech detection using both traditional machine learning (Ridge Classifier with TF-IDF) and transformer-based models (LaBSE). We evaluate performance across four languages English, Spanish, Urdu, and German using the PolyHope dataset. Experimental results demonstrate that LaBSE consistently outperforms the Ridge baseline, particularly in low-resource settings like Urdu. Our findings highlight the effectiveness of multilingual transformers in capturing nuanced expressions of hope across diverse linguistic and cultural contexts.
