Hi
Thanks for reading my post
I work on my master thesis and I find same my problem here in this link
http://community.rapidminer.com/t5/RapidMiner-Studio/SOLVED-Filter-text-from-a-list-of-word/td-p/21459
He solve the problem by changing the code for filterstopword(dictionary)
I read the document "How to extend rapidminer"
I prepare the envirmonet by downloding Java and Eclipse Java Neon
I know now how to create my own operator but I don't know how to copy existing operator code and modify it ?
Thank you again
