TITLE: Using Words from Daily News Headlines to Predict the
       Movement of Stock Market Indices


Stock market analysis is one of the biggest areas of interest for text mining. Many researchers proposed different approaches that use text information for predicting the movement of stock market indices. Many of these approaches focus either on maximising the predictive accuracy of the model or on devising alternative methods for model evaluation. On the seminar, we will describe a more descriptive approach focusing on the models themselves, trying to identify the individual words in the text that most affect the movement of stock market indices. Data from two sources will be used: the daily data for the Dow Jones Industrial Average index (“open” and “close” values for each trading day) and the headlines of the most voted 25 news on the Reddit WorldNews Channel for the previous “trading days” (data has been gathered for the past 8 years). By applying machine learning algorithms on these data and analysing individual words we will show that certain words have a "positive" effect on stock indices while other words have a clearly "negative" effect.
