Hi, everyone,
I am using rapidminer to do sentiment analysis according to the following website.
http://kmandcomputing.blogspot.com/2008/06/opinion-mining-with-rapidminer-quick.html.
I am using the latest version of rapidminer to do it.
Here is the codes:

The data set comes from this website: http://www.cs.cornell.edu/People/pabo/movie-review-data/
I downloaded polarity dataset v0.9 to use sentiment analysis.
However, the simulating process is more than 2 days and still continuing. What wrong is it? I cannot understand why the process is running for more than 2 days? Is it common? Look forward to hearing from you soon.
Many thanks,
Sunny
