The widespread adoption of social media platforms has led to an influx of data that reflects public sentiment, presenting a novel opportunity for market analysis. This research aims to quantify the correlation between the fleeting sentiments expressed on social media and the measurable fluctuations in the stock market. By adapting a pre-existing sentiment analysis algorithm, we refined a model specifically for evaluating the sentiment of tweets associated with financial markets. The model was trained and validated against a comprehensive dataset of stock-related discussions on Twitter, allowing for the identification of subtle emotional cues that may predict changes in stock prices. Our quantitative approach and methodical testing have revealed a statistically significant relationship between sentiment expressed on Twitter and subsequent stock market activity. These findings suggest that machine learning algorithms can be instrumental in enhancing the analytical capabilities of financial experts. This article details the technical methodologies used, the obstacles overcome, and the potential benefits of integrating machine learning-based sentiment analysis into the realm of economic forecasting.
社交媒体平台的广泛采用导致了反映公众情绪的数据大量涌入,为市场分析提供了一个新机会。本研究旨在量化社交媒体上表达的短暂情绪与股票市场可测量波动之间的相关性。通过采用预先存在的情绪分析算法,我们改进了一个专门用于评估与金融市场相关推文情绪的模型。该模型针对Twitter上与股票相关讨论的综合数据集进行了训练和验证,从而能够识别可能预测股价变化的微妙情绪线索。我们的定量方法和系统测试揭示了Twitter上表达的情绪与随后的股票市场活动之间存在统计学上的显著关系。这些发现表明,机器学习算法有助于提高金融专家的分析能力。本文详细介绍了所使用的技术方法、克服的障碍以及将基于机器学习的情绪分析整合到经济预测领域的潜在好处。
