Hello @WanRashid,

You can use the ‘Tagged Document Viewer’ node to visualize how the words are tagged in the product descriptions.

Since your use case requires tagging specific product keywords, I suggest the following steps:

  1. Create a dictionary with all the possible product values (e.g., Printer, Gun, Support) in a CSV or KNIME table format.
  2. Use the Dictionary Tagger node, providing it with the dictionary you created. This will tag the product values within your descriptions.

Once tagged, you can extract the relevant terms and review them using the ‘Tagged Document Viewer’ node for verification.

I hope this helps!

Best,
Keerthan
