Text processing error: No column containing TermCells found! attempting to vectorize documents


Brand new KNIME user here!   I am trying to do text processing on Reuters data to do classification.  I have gotten as far as pre-processing.  Now in order to vectorize data I want to be able to use DF or IDF but I seem to be missing an intermediate processing step that will create TermCells - I'm not sure what that is and how I can create the.  Any help is appreciated.





to create TermCells, you have to use the Bag of Words creator. This node will give you an extra column containing one term per row. DF and IDF can be easily used by then.
