股票市场的走势受到通过新闻文章、公司报告和社交媒体讨论分享的公共和私人信息的影响。分析这些庞大的数据来源可以为市场参与者提供获利的优势。然而,文献中的大多数研究都是基于传统的方法,在分析非结构化的,大量的文本数据不足。在这项研究中,我们提供了一个基于文本的股票市场分析的大量现有文献的回顾。我们介绍了输入数据类型,并涵盖了主要的文本数据源和变体。特征表示技术,然后提出。然后,我们涵盖了分析技术和创建一个分类的主要股票市场预测模型。重要的是,我们讨论了分类法中每个类别的代表性工作,分析了它们各自的贡献。最后,本文展示了未解决的开放问题的调查结果,并提出了未来工作的建议。本研究的目的是综述主要的股票市场分析模型、用于金融市场预测的文本表示技术、现有技术的不足,并提出未来研究的方向。

英文摘要:

Stock market movements are influenced by public and private information shared through news articles, company reports, and social media discussions. Analyzing these vast sources of data can give market participants an edge to make profit. However, the majority of the studies in the literature are based on traditional approaches that come short in analyzing unstructured, vast textual data. In this study, we provide a review on the immense amount of existing literature of text-based stock market analysis. We present input data types and cover main textual data sources and variations. Feature representation techniques are then presented. Then, we cover the analysis techniques and create a taxonomy of the main stock market forecast models. Importantly, we discuss representative work in each category of the taxonomy, analyzing their respective contributions. Finally, this paper shows the findings on unaddressed open problems and gives suggestions for future work. The aim of this study is to survey the main stock market analysis models, text representation techniques for financial market prediction, shortcomings of existing techniques, and propose promising directions for future research.
