The empty result

In the chpater3’s examples of “from words to wisdom” material, why the result document column is empty after any processing?

Hi @ahmed_gomaa -

I assume you are referring to Chapter 3, Exercise 3 about filtering, stemming, and lemmatization?

Here the document only appears empty in the regular KNIME table view, because that view only displays the title, and not the document text or other associated meta information. If you use a Document Viewer or Tagged Document Viewer node, you will see that the documents are not actually empty. However, they have been trimmed down quite a lot because the Tag Filter node is removing nouns, verbs, and adjectives, which doesn’t leave much to display.
