"[MOVED] Filter text from a list of word"

johan_CG

Hi everybody,

I build a process to search and count a list of keywords in thousands of files.
I built the keywords list from a Excel file after seraval operations in an example set with a keyword by example.

I would like to be able to do something like an inverse of "Filter stopwords (Dictionary)" using the attribute of my example set (or a word list if someone can explain me how to convert an example set attribute into a word list).

I found the following topics but I don't know if there is something new since:

• http://rapid-i.com/rapidforum/index.php/topic,2754.0.html
• http://rapid-i.com/rapidforum/index.php/topic,6330.0.html
• http://rapid-i.com/rapidforum/index.php/topic,3719.0.html
• http://rapid-i.com/rapidforum/index.php/topic,3493.0.html

In these topics they talk about using "Filter Tokens (by Content)" operator with "matches" and the words in the regular expression but I can't use this solution because I have tens of keywords list with hundreds of keywords each. They talk also about modify the source code "Filter stopwords (Dictionary)" operator, is somebody able to tell me where I can find the source code of the operator and how to install my own operator in RapidMiner?

Thanks in advance
Johan
