Text Analytics with RapidMiner Part 6 of 6 - Applying the Model to New Documents

After my last series, I got a lot of questions about how to apply a model to new data, so here is the real final installment in the series.

I show how to save a wordlist and model to the repository. I use them later to read the wordlist and model and apply them to new documents that RapidMiner hasn't seen before. It correctly labels 11 of the 12 documents.
