Hi,
the TF Nodes description is not quite accurate as there is an option, which is enabled by default, to count the absolute occurrence of words if it is disabled.
Computes the relative term frequency (tf) of each term according to eachdocument and adds a column containing the tf value. The value iscomputed by dividing the absolute frequency of a term according to adocument by the number of all terms of that document.
I’d also like to suggest to merge that tab with the first to increase visibility of that crucial option, hence both flags bug and feature-request.
PS: The node name “TF” might be worth changing to “TF - Term Frequency” to make it easier to distinguish especially for newcomers. Same goes for some of the other frequency node names too:
