Sentiment Analysis using Machine Learning
1)I have, hence, added a "Sentiment" column in the excel file where I've stored the data after fetching it from Twitter. But this column is automatically getting removed after I use the Process Documents from Data operator. I can't understand why.
2) I can't understand how to analyse the sentiment using any Machine Learning Algorithm after the pre processing of data.
Please the find the .rmp process and the dataset attached below. Can anyone please help me find a solution to my problem? Urgent help is needed.
