Random sampling of a large corpus

How can you pick a random sample from a large corpus for files to perform pre-processing and text mining with the text mining extension? Is there an operator that does that?

Hi frankc,

just a quick question. Do you want to read a random set of files or read all files and shuffle a random set of documents?

Cheers,
Helge

You should be able to use the Sample operator and select "use local random seed" to select a random sample, similar to a non-text data set.
