This paper surveys the field of financial analysis using news data, and also the authors' own considerable work regarding movie gross analysis to show the predictive power of news data. Since the 1990s, linguistic sources such as news have been continuously proved to carry extra and meaningful information beyond traditional quantitative finance data, and thus they can be used as predictive indicators in finance. In the first half of this paper, the authors analyze and compare important previous research in terms of targets, methodologies, and results.
