Text Classification using Text Plugin

Hi,

I am trying to classify texts stored in a database. I'd like to describe some of the problems I experienced and questions that came up. Since they adress different topics I decided to split the post into three parts. In this one I ask for your opinion: How would you design an experiment for text classification with RapidMiner? If anyone has built a similar experiment I would be very grateful if he could describe the setup he used.

The setup I have in mind at the moment is something like this:














<参数键=“prune_below”值="3"/>


































This is just the part for learning the model. Of course normally a part where the model is applied to unlabeled data would follow. Later on I'd like to create the wordlist from the database entries (at the moment I work with a given wordlist) and use the UpdateModel operator to update the model incrementally with new labeled data. More about this in my other posts in "Problems and Support".
