Help with Punctuation Erasure

[josechavez]

Hello everyone…

I want to delete all the rows with punctuation marks using the “punctuation erasure” node but when configuring I cannot select the “Term” column obtained from “BoW”. I am new to this, I would appreciate your help please.

Thanks,
Jose

@josechavez welcome to the knime forum. I can offer this somewhat older collection of articles about knime and text Processing.

In general your text will be converted into a document data format and then all manipulation steps will be added on top. So the punctuation erasure will be done on your document column.
