Hi,

once you have imported your files via one of the various import operators or one of the import wizards (Files -> Import Data), you can concatenate example sets via the "Append" operator.

Thanks, I already imported the files from a database remotely + my local desktop.

I do not need to concatenate Example Sets, I need to concatenate actually text files as in file-concatenate.

I tell you why:

1. We want to associate a series of files to each other e.g. HR documents for one employee
2. We want to perform text classification on the entire series of documents, not just one
3. So I thought a crude setup would be to concatenate all the files for one employee and treat it as a single file

Hi,

to read multiple files for text classification, you can use the "Process Documents from Files" operator. There should be plenty of help available in the forums because text mining questions are pretty common

Hi,

I quickly created a process to read files, concatenate the contents and write to another file. See if you can adapt this to your needs.

enjoy,
Matthew

Thanx Matthew

It works! Impressed.

Could you kindly tell me how to make this a separate process by itself, like an IO box to use in other processes? I am not sure how to do this in general i.e. making my own processes from others

To make it a separate process - Save and call from your process using 'Execute Process' operator. I have not tried this though.
You can also add this to your process - just copy and paste to your process (at top level or inside a 'Subprocess' operator. Do this in the Process window, not in XML.
