Filtering words for tag cloud

Hello Knime Community,

I hope somebody can help me. I have filtered my words for my tag Cloud but there are still words I don’t want. Is there a node to filter selected words maybe a drag and drop filter or something like a blacklist or whitelist filter.

Thank you very much for your help.

Hi @CClausius,

You can use the Dictionary Filter node for this. This allows you to provide a dictionary table with all the words you want to filter. If the list is not too large, the easiest way to do this is to just take a Table Creator node and enter the terms manually.

Cheers,

Hi,

thanks for your help. I tried to use the dictionary filter but an errors shows up with “There have to be at least 1 columns containing DocumentCells !”. My filter ist between the Sorter node and my tag cloud.

That is correct, the text processing nodes in KNIME generally need a document column as input. This means that you have to apply the Dictionary Filter before you transform to a Bag of Words. If you want to share your workflow, I can give you some pointers how to set this up.

Cheers,
Roland
