The rapid expansion of the digital world has propelled sentiment analysis into a critical tool across diverse sectors such as marketing, politics, customer service, and healthcare. While there have been significant advancements in sentiment analysis for widely spoken languages, low-resource languages, such as Bangla, remain largely under-researched due to resource constraints. Furthermore, the recent unprecedented performance of Large Language Models (LLMs) in various applications highlights the need to evaluate them in the context of low-resource languages. In this study, we present a sizeable manually annotated dataset encompassing 33,605 Bangla news tweets and Facebook comments. We also investigate zero- and few-shot in-context learning with several language models, including Flan-T5, GPT-4, and Bloomz, offering a comparative analysis against fine-tuned models. Our findings suggest that monolingual transformer-based models consistently outperform other models, even in zero and few-shot scenarios. To foster continued exploration, we intend to make this dataset and our research tools publicly available to the broader research community. In the spirit of further research, we plan to make this dataset and our experimental resources publicly accessible to the wider research community.

本研究通过33,605条孟加拉文新闻推文和Facebook评论创建了一个庞大的手动注释数据集，并对Flan-T5、GPT-4和Bloomz等多种语言模型进行了零指导和少量指导的上下文学习，与精细调优模型进行了比较分析。研究结果表明，在零指导和少量指导的场景下，单语言变换器模型始终优于其他模型。为了促进进一步的研究探索，我们打算向更广泛的研究社区公开提供这个数据集和我们的研究工具。
