N Chars Filter

This Node Is Deprecated — This version of the node has been replaced with a new and improved version. The old version is kept for backwards-compatibility, but for all new workflows we suggest to use the version linked below.

Filters all terms consisting of words with altogether less than the specified number N characters.

Options

Preprocessing options

N Chars: Specifies the number of minimum characters of a term.

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.

Input Ports

: The input table which contains the terms to convert.

Output Ports
