Feature Extraction of Palladian Text Classifier

Hi, I am trying to extract features which are the direct input of the classifier inside Palladian TextClassifier. I just know that those features (maybe some vectors) are pre-processed via n-gram, how can I collect them?

Cheers, TD

Hi TD,

the Palladian Text Classifier node requires input via a custom input port (which is indicated through the grey square ports). Following the standard KNIME principle, there is a Learner and a Predictor node, the first node is used for creating the model which is then passed to the Predictor node.

A working example workflow can be found here: https://tech.knime.org/book/text-classifier

Hope that helps, in case you have further questions let me know.

Best,
Philipp
