> Can I perform the preprocessing steps and then save the file so that we can apply it with other tools also like R, Python etc. You mean like using the "Save" button in the Explorer? Usually, it is recommended to wrap any preprocessing steps into the FilteredClassifier to avoid any information leakage (eg class information) and generating overly optimistic cross-validation results. The StringToWordVector, though listed under the "unsupervised" package, can act like a supervised one depending on some of its options.
