Error in Chi-square Keyword Extractor result

#1

Hi all,

In attached knime workflow I am simply reading data about movie reviews. If I set document title as “empty string” or “row ID” results are changing. Odd thing about this, anyways I am filtering title to empty string even if I set it as row ID with Number Filter.

C4_E2.knwf (22.2 KB)

Why and how are results changing? I think it should not change.

Thank you for discussion…

Hi @asenkron,

that sounds interesting…
Would it be possible to share also the data that you use in the workflow?
I’m not 100% sure that i fully understand what are the 2 alternative scenarios. Could you maybe add two parallel branches in a workflow doing slightly different processing and highlight what is different between the branches? This would help to start debugging faster.

Cheers,
Mischa

Best regards,
