Link Columns

Hello everyone,

I’ve done some processing. Because I used “String to Document” for the preprocessing and “Sentence Extractor” to convert the column back to string, I lost the previously contained columns. I did these steps for 4 columns. If I now want to merge the columns again it somehow doesn’t work.

This is my workflow:

Did I anything wrong?

Cheers,

Sorry guys,

I found the Problem. In the Strings to Document node i have to set in the Configuration “Empty Strings”.

Cheers,
Canan
