Keyword Based Classifier


Incorporates a keyword-based document classification algorithm, targeting classification for files that have repeatable titles.
Classifies a document based on a given training set, found in a specified file, if used inside the Classify Document Scope activity.
Enhances the training set to be used for classification, by writing learning data in a specified file, if used inside the Train Classifiers and Extractors scope activity.
This activity can only be used inside one of the Classify Document Scope and Train Classifiers Scope activities.



  • DisplayName - The display name of the activity.


  • LearningFilePath - The full path to the file containing the classifier data. This field supports only strings and String variables.


The activity does not automatically create a file at the specified location. A best practice is to create an empty .JSON file at that location.


  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
