Spell Checker (simple)

Go to Product

Spell checker and corrector based on LanguageTool. LanguageTool is an Open Source proof­reading program for more than 25 languages. It finds many errors that a simple spell checker cannot detect.

This node automatically corrects the input text by applying all rules which LanguageTool detected (hence the appendix “simple”). In case, you need more control over the corrections (e.g. only correct certain categories of errors), use the “Spell Checker: Create Rules” node, inspect and filter the rules using standard KNIME nodes (e.g. “Row Filter”), and then finally apply your rules using the “Spell Checker: Apply Rules” node.

N-gram Data

Selected Directory
(Optional) Directory which contains an n-gram data set. This allows to detect errors with words that are often confused, like their and there. The n-gram data sets need to be downloaded separately and are available here. After downloading, unzip the file and put it in its own directory named “en”, “de”, “fr”, or “es”, depending on the language. The path you need to set in the configuration is the directory that the “en” etc. directory is in, not that directory itself. More information can be found here.
