Spacy Lemmatizer

The node converts all tokens to their root form (lemma), removing cases, plurals, conjugations, etc. Not all spaCy models contain lemmatizer.

If a model doesn't provide this functionality, a corresponding error is displayed upon configuration of the node.

Options

Select column: Select a Document column that will be affected by lemmatization.
Replace column: If checked, the document column will be replaced by the new preprocessed documents. Otherwise the preprocessed documents will be appended as a new column.
Append column: The name of the newly appended column, containing the preprocessed documents.

Python

use default Python environment for the Redfield NLP nodes
