"Text Mining - How to?"
Contributor I
Hi I am very new to Rapid-I / Rapid Miner and was hoping someone might be able to help me get my head around some text mining issues.
I have a data set which is all free text responses to a question. Each answer is on a separate line. I am wanting to do some clustering/visualisation/analysis of the key themes that come out in the question responses. I can successfully import my text (although it seems to make it all the heading of the columns with no actual data).
Can someone give me an idea of how I might format my data accordingly such that it imports fine for text mining.
Also any additional tips on how I might be able to use it for visualisation would be a great help.
Thanks in advance

the Text Mining Plugin provides some very usefull example processes. If you visit the download section of the text plugin on source forge, there is a file called rapidminer-text-4.3-examples.zip which providing them. It might help if you take a look in the tutorial, too. It is available on the same download page.
Greetings,
