Sentiment Analysis using AYLIEN
I am new user of RapidMiner. I am interested to do research using twitter data for sentiment analysis. I follow tutorial from this link : http://blog.aylien.com/building-a-twitter-sentiment-analysis-process-in/
From my understanding, this process is using real time data from twitter. Does anyone know how to read data from database (e.g. excel, csv, SQLite) and apply Sentiment Analysis from that data.
Thank for your help.
