Hi,
where exactly is your problem regarding the text plugin? Unfortunately the text plugin fills a complete two day training course, so that I cannot explain everything. In order to help you, you will have to be more detailed in your descriptions.

Dear Sebastian
The problem is how to classify texts.

I know that to learn RapidMiner we put the texts in folders. So every folder presents a class.

Now i want RapidMiner to classify texts. I mean i want to give it  a mixed collection of texts. After classification where is the Rapidminer put texts. Or may be it writes something in a  text as a  label.

Please help me

Thank you

regards

Hi,
Usually RapidMiner does not write the texts back in files. After classifying, you have an exampleSet, containing the TermVector and a predicted label. You have to keep track of the text yourself, hence keep it in the exampleSet as a special attribute. After all, you could write the texts back into files. Since a more complex process setup is needed to achieve this, you should make yourself familiar with the various operators available for attribute handling, macro definition within the process and meta operators. If you played around a bit, you will see, how to  solve any related problem.
