counting a specific word in the text

KNIME Extensions

Hello,

I am trying to count a specific word “RT” in the text file I have. However, it needs to in capital so case-sensitive. I am trying the workflow that I attached but couldn’t quite sure which function to select in the dictionary tagger node for this. I also got error when I tried to export the output. I would be glad if you can help me with this. Thanks!

Hi,

If you have installed Python you can try with Python String.count() function (https://pythonexamples.org/python-count-occurrences-of-word-in-text-file/). There are a lot of functions in Python which you can use to count words frequency (https://www.w3resource.com/python-exercises/string/python-data-type-string-exercise-12.php).
