AI总结:

本研究评估了多种BERT变体在尼泊尔语句子级主题分类中的性能,发现印度语模型MuRIL-large表现最佳,F1分数达90.60%。

摘要:

基于Transformer的模型如BERT在许多语言的自然语言处理(NLP)中取得了显著进展。然而,尼泊尔语作为一种书写在德文纳里 script 上的低资源语言,仍然相对未被探索。本研究对多语言、印度语、印地语和尼泊尔语的BERT变体进行基准测试,以评估其在尼泊尔语主题分类中的有效性。十种预训练模型,包括mBERT、XLM-R、MuRIL、DevBERT、HindiBERT、IndicBERT和NepBERTa,在平衡的尼泊尔语数据集上进行了微调和测试,该数据集包含25,006个句子,涵盖五个概念领域。性能通过准确率、加权精度、召回率、F1分数和AUROC指标进行评估。结果表明,印度语模型,特别是MuRIL-large,取得了90.60%的最高F1分数,优于多语言和单语言模型。NepBERTa也表现出竞争力,F1分数为88.26%。总体而言,这些发现为未来文档级分类和更广泛的尼泊尔语NLP应用建立了稳健的基准。

英文摘要:

Transformer-based models such as BERT have significantly advanced Natural Language Processing (NLP) across many languages. However, Nepali, a low-resource language written in Devanagari script, remains relatively underexplored. This study benchmarks multilingual, Indic, Hindi, and Nepali BERT variants to evaluate their effectiveness in Nepali topic classification. Ten pre-trained models, including mBERT, XLM-R, MuRIL, DevBERT, HindiBERT, IndicBERT, and NepBERTa, were fine-tuned and tested on the balanced Nepali dataset containing 25,006 sentences across five conceptual domains and the performance was evaluated using accuracy, weighted precision, recall, F1-score, and AUROC metrics. The results reveal that Indic models, particularly MuRIL-large, achieved the highest F1-score of 90.60%, outperforming multilingual and monolingual models. NepBERTa also performed competitively with an F1-score of 88.26%. Overall, these findings establish a robust baseline for future document-level classification and broader Nepali NLP applications.
