Term Grouper

Groups all terms of a document by their text and deletes all tags, conflicting tags only or combines all tags, accordant to the users settings.

Options

Preprocessing options

Tag policy

Specifies whether all tags of grouped terms will be kept "Keep all", all tags will be deleted "Delete all" or only these tags will be deleted which tag types conflict. For instance terms containing the same string with one "POS" assigned to each will be grouped and the tags are deleted, cause of the conflicting tag type (POS).

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.
