Abstract: The integration of pretrained language models (PLMs) like BERT and GPT has
revolutionized NLP, particularly for English, but it has also created
linguistic imbalances. This paper strategically identifies the need for
linguistic equity by examining several knowledge editing techniques in
multilingual contexts. We evaluate the performance of models such as Mistral,
TowerInstruct, OpenHathi, Tamil-Llama, and Kan-Llama across languages including
English, German, French, Italian, Spanish, Hindi, Tamil, and Kannada. Our
research identifies significant discrepancies in normal and merged models
concerning cross-lingual consistency. We employ strategies like 'each language
for itself' (ELFI) and 'each language for others' (ELFO) to stress-test these
models. Our findings demonstrate the potential for LLMs to overcome linguistic
barriers, laying the groundwork for future research in achieving linguistic
inclusivity in AI technologies.
