In Importing, preprocessing and visualizing textual data as Tag Cloud, there’s an apparently empty preprocessor node. But the Abner Tagger can’t connect directly to either the Tag Filter or the Bag of Words Creator, it has to run through the preprocessor node. What’s going on?
Hi @Bart_Humphries -
What’s labeled as “Preprocessing” in the workflow isn’t actually an empty node, but rather a metanode containing a few simple filtering and stemming nodes- you can double click the metanode to go inside and see exactly what it’s doing.
I was able to connect the Abner Tagger downstream and bypass the Preprocessing metanode, but you don’t really want to do that as the metanode contains some useful cleanup functions. To make it work I had to open the configuration of the downstream Tag Filter and click OK before it would execute, even though I didn’t change any settings:
