Social media platforms are rife with politically charged discussions. Therefore, accurately deciphering and predicting partisan biases using Large Language Models (LLMs) is increasingly critical. In this study, we address the challenge of understanding political bias in digitized discourse using LLMs. While traditional approaches often rely on finetuning separate models for each political faction, our work innovates by employing a singular, instruction-tuned LLM to reflect a spectrum of political ideologies. We present a comprehensive analytical framework, consisting of Partisan Bias Divergence Assessment and Partisan Class Tendency Prediction, to evaluate the model's alignment with real-world political ideologies in terms of stances, emotions, and moral foundations. Our findings reveal the model's effectiveness in capturing emotional and moral nuances, albeit with some challenges in stance detection, highlighting the intricacies and potential for refinement in NLP tools for politically sensitive contexts. This research contributes significantly to the field by demonstrating the feasibility and importance of nuanced political understanding in LLMs, particularly for applications requiring acute awareness of political bias.

通过使用大规模语言模型（LLMs）来准确解读和预测政治偏见在社交媒体平台上充斥的政治性讨论，本研究创新性地采用了一个指导调整的LLM，以反映一系列政治意识形态。我们提出了一个综合的分析框架，包括党派偏见差异评估和党派倾向预测，以评估模型在立场、情绪和道德基础等方面与现实政治意识形态保持一致。研究发现模型在捕捉情绪和道德细微差别方面的有效性，但在立场检测方面存在一些挑战，突显了NLP工具在政治敏感环境中精细化和改进的复杂性和潜力。此研究通过展示LLMs中细致的政治理解的可行性和重要性，特别适用于需要敏锐意识到政治偏见的应用，为该领域做出了重要贡献。
