meets text information retrieval. While there have been quite extensive studies on stock price prediction based on news, much less work can be found on simultaneously leveraging the correlations (1) among stock prices, (2) among news articles, and (3) between stock prices and news articles [4]. In this paper, we revisit the stock price Predicting Stock Price Movements Based on Different Categories of News Articles. Pr edicting Stock Price Movements Based on Different . stock price prediction system that uses time series Therefore, being able to predict movements in GDP is the key to predicting stock market moves. How do you predict GDP, you ask? the ISM will have some influence over that stock price. One area of limited success in Stock Market prediction comes from textual data. Information from quarterly reports or breaking news stories can dramatically affect the share price of a security. Most existing literature on financial text mining relies on identifying a predefined set of keywords and machine learning techniques. Previous attempts to use machine learning techniques to exploit such information to predict price movements have relied on using a pre-identified set of keywords. Here, Schumaker and Chen experiment with using other linguistic elements for prediction, specifically bags of words, noun phrases, and named entities.
