Hello,
I would never do this analysis without including a Document ID (to be able to find everything back afterwards and to be able to link / map everything).
I wasn't even aware you could do this analysis without including a Document ID.
The procedure that is run in the background is PROC TEXTMINE.
PROC TEXTMINE has a DOC_ID Statement. I think that DOC_ID Statement is mandatory.
DOC_ID Statement
The DOC_ID statement specifies the variable that contains the ID of each document. In the input data table, each row corresponds to one document. The ID of each document must be unique; it can be either a number or a string of characters.
Kind regards,
Koen
