Random sampling of a large corpus
frankc
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,

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.
