hi, i was wondering what the pattern expresion for the row filter node was in order to get the top 10 frequent words,

 

i used bag of words, then TF, then Sorter. However once i get onto the row filter i do not know what the pattern is that needs to be entered in order to filter top 10 freuent terms,

Use a GroupBy (grouping on terms) after TF and than Sort. Does that help?

Alternatively use the Frequency Filter. This node allows you to filter the K most frequent words based on a frequency or score.

Cheers, Kilian
