Kuhlen Stemmer

This node allows you to reduce terms to their stem. The used stemming algorithm is the Kuhlen stemmer. The stemmed terms are stored in the outgoing DataTable, as well as the documents containing these terms. Be aware that the Kuhle stemmer stems only english words correctly.

Options

Deep preprocessing options

Deep preprocessing

If deep preprocessing is checked, the terms contained inside the documents are preprocessed too, this means that the documents themselves are changed too, which is more time consuming.

Document column

Specifies the column containing the documents to preprocess.

Append unchanged documents

If checked, the documents contained in the specified "Original Document column" are appended unchanged even if deep preprocessing is checked. This helps to keep the original documents in the output data table without the agonizing pain of joining.

Original Document column

Specifies the column containing the original documents which can be attached unchanged.

Ignore unmodifiable tag

If checked unmodifiable terms will be preprocessed too.
