Hi,

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.

 

regards,

Saip

    Dear Salip,

    simply replace the read Twitter operator with a Read Excel/CSV/Database operator. For databases you need to setup the connection in the Connections window.

    Hi,

     

    Firt time run, it's work well.

    Second time run with the same dataset, no result (...??) in polarity, subjectivity, polarity_confidence and subjectivity_confidence.

    Any suggestions?

    Hey,

    the AYLIEN offering has 1000 calls per day for free. If you run more than these thousand it will add missings (?-signs).
