This repository contains the TradeMiner RapidMiner extension that performs Stock Price Change Prediction using Text Mining, and the respective experiments, according:
Beckmann, M., Ebecken, N.F.F., De Lima, B.S.L.P, 2017, PhD Thesis: Stock Price Change Prediction using News Text Mining, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil. https://www.researchgate.net/publication/313473231_Stock_Price_Change_Prediction_Using_News_Text_Mining/comments
Let me know if you have any question to setup and run the experiments.
Later on I'll prepare a setup and run manual for this.
Glad to help,
