01_​Frequencies

01_Frequencies and other Measures Computation

After creating BoW we can compute frequencies and other important measures based on terms, characters, co-occurences, etc.
The nodes applied are TF, IDF, ICF, Term Document Entropy, DF, Term o-ccurance counter, and NGram creator. Moreover, the workflow shows how to compute the tf*idf measure and an application of the computed frequencies and measures.
All nodes preceding the computation of the frequencies and the other measures have been encapsulated in components, to make the workflow better readable.
