Oscar Filter

DeprecatedKNIME Textprocessing Plug-in version 4.3.0.v202011212014 by KNIME AG, Zurich, Switzerland

Filters all terms contained in the given bag of words (input table) with chemical named entities tags assigned, (not) specified in the dialog. The terms are filtered out of the bag of words and the documents as well if deep preprocessing is checked.
To detect chemical named entities, the OSCAR framework version 4.1.2 is used (see https://bitbucket.org/wwmm/oscar4/overview for details).
A term is kept if at least one of its assigned chemical tags is a valid tag. If strict filtering is set, all assigned chemical tags of a term have to be valid.

Options

Preprocessing options

Strict filtering: If strict filtering is checked, terms need to have all specified tags applied. If not checked, at least one tag has to be applied.
Filter matching: If checked, terms which have the specified tags are filtered, otherwise they are kept. If strict filtering is checked, all tags must match to filter or keep a term.
Tags: The tags to filter for.

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 filter.

Output Ports

: The output table which contains the filtered terms.
